The '''MIM-104 Patriot''' is a mobile interceptor missile [[surface-to-air missile]] (SAM) system, the primary such system used by the [[United States Army]] and several allied states. It is manufactured by the U.S. defense contractor [[Raytheon]] and derives its name from the [[radar]] component of the weapon system. The AN/MPQ-53 at the heart of the system is known as the "Phased Array Tracking Radar to Intercept on Target",<ref name=":1">{{Cite news |date=December 14, 2012 |title=US sends 400 troops with Patriot missile batteries to Turkish frontier |work=Daily Telegraph}}</ref> which is a [[backronym]] for "Patriot". In 1984, the Patriot system began to replace the [[Nike Hercules]] system as the U.S. Army's primary [[high to medium air defense]] (HIMAD) system and the [[MIM-23 Hawk]] system as the U.S. Army's medium tactical air defense system.<ref name=":0">{{Cite news |date=November 13, 1984 |title=Patriot missile ready for field |work=United Press International |quote=The first deployment to Western Europe of the Army's new Patriot anti-aircraft missile will begin later this month, six months later than scheduled because of testing problems, the Army said Tuesday.

Patriot uses an advanced aerial interceptor missile and high-performance radar systems. Patriot was developed at [[Redstone Arsenal]] in [[Huntsville, Alabama]], which had previously developed the [[Safeguard Program|Safeguard]] ABM system and its component [[LIM-49A Spartan|Spartan]] and [[hypersonic speed|hypersonic]] [[Sprint (missile)|Sprint]] missiles. The symbol for Patriot is a drawing of a [[American Revolutionary War|Revolutionary War]]–era [[Minutemen (militia)|minuteman]].

The MIM-104 Patriot has been widely exported. Patriot was one of the first tactical systems in the U.S. Department of Defense (DoD) to employ [[Lethal autonomous weapon|lethal autonomy]] in combat.<ref>{{cite web|url=http://www.css.ethz.ch/en/services/digital-library/articles/article.html/976797da-7b8b-4e86-84f4-4052f394d2e1|title=Patriot Wars: Automation and the Patriot Air and Missile Defense System|last=Hawley|first=John K.|date=February 8, 2017|archive-url=https://web.archive.org/web/20180612143306/http://www.css.ethz.ch/en/services/digital-library/articles/article.html/976797da-7b8b-4e86-84f4-4052f394d2e1|archive-date=June 12, 2018|url-status=dead|access-date=June 11, 2018}}</ref> The system saw poor performance in the 1991 [[Gulf War]], without any confirmed interceptions of Iraqi [[Scud missiles]], but made successful intercepts in the 2003 [[Iraq War]].

In August 2014 batteries first downed [[UAVs]] when [[Israeli Air Defense Command]] engaged two [[Hamas]] drones during [[Operation Protective Edge]]. In September 2014, Patriot first shot down a crewed aircraft, when an Israeli battery intercepted a [[Syrian Air Force]] [[Sukhoi Su-24]] .<ref name="ynetnews.com" /> Since 2023, Patriot systems have been used by Ukraine in the [[Russo-Ukrainian war (2022–present)|Russo-Ukrainian war]], downing Russian [[Sukhoi Su-34|Su-34]] and [[Sukhoi Su-35|Su-35]] fighters, [[Mil Mi-8|Mi-8]] helicopters, and [[Kh-47M2 Kinzhal|Kinzhal]] ballistic missiles.

==Introduction==
Prior to the Patriot, Raytheon was involved in a number of surface to air missile programs, including FABMDS (Field Army Ballistic Missile Defense System), AADS-70 (Army Air-Defense System – 1970) and SAM-D (Surface-to-Air Missile – Development).<ref>{{cite book|last=Delaney|first=William P.|title=Perspectives on Defense Systems Analysis|url=https://books.google.com/books?id=S7K2CAAAQBAJ&pg=PA64|year=2015|publisher=MIT Press|isbn=978-0-262-02935-3|page=64}}</ref> In 1975, the SAM-D missile successfully engaged a drone at the [[White Sands Missile Range]]. In 1976, it was renamed the PATRIOT Air Defense Missile System. The MIM-104 (Mobile Interceptor Missile 104) Patriot combined several new technologies, including the MPQ-53 [[passive electronically scanned array]] radar and [[track-via-missile]] guidance.

Full-scale development of the system began in 1976 and it was deployed in 1984.<ref name=":0" /> Patriot was used initially as an anti-aircraft system. In 1988, it received an upgrade providing limited capability against [[tactical ballistic missile]]s (TBM), designated PAC-1 (Patriot Advanced Capability 1). The most recent upgrade by manufacturer Lockheed Martin, designated PAC-3, is a nearly total system redesign of the interceptor missiles, this time designed from the outset with the capability to engage and destroy tactical ballistic missiles.<ref>{{cite news|url=https://missilethreat.csis.org/system/patriot/|title=CSIS Missile Threat Defense Project: Patriot|author=CSIS|access-date=October 3, 2024}}</ref> The Army plans to upgrade the Patriot system as part of the [[Integrated Air and Missile Defense]] system designed to tie into a broader air defense architecture using an Integrated Battle Command System (IBCS).<ref name="DefNews4924" />

===Patriot equipment===
[[File:Soldiers from the 31st Air Defense Artillery Brigade at work.jpg|thumb|left|Soldiers from the 31st Air Defense Artillery Brigade conducting reload from a Guided Missile Transporter (GMT)]]
The Patriot system has four major operational functions: communications, command and control, radar surveillance, and missile guidance. The four functions combine to provide a coordinated, secure, integrated, mobile air defense system.

The Patriot system is modular and highly mobile. A [[#Patriot battalion|battery]]-sized element can be installed in less than an hour. All components, consisting of the fire control section (radar set, engagement control station, antenna mast group, electric power plant) and launchers, are truck- or trailer-mounted. The radar set and launchers (with missiles) are mounted on M860 semi-trailers, which are towed by [[Oshkosh Corporation|Oshkosh]] M983 [[Heavy Expanded Mobility Tactical Truck|HEMTTs]].

[[File:Operator in de ICC (Information Coordination Central center) van een Nederlandse Patriot-batterij bij Brakstadt in Noorwegen (2009 D040309-C1204).jpg|thumb|right|An operator in the Information Coordination Central (ICC) monitors the actions of the battery via his display]]
Missile reloading is accomplished using a [[Heavy Expanded Mobility Tactical Truck|M985 HEMTT]] truck with a Hiab crane on the back. This crane is larger than the standard Grove cranes found on regular [[Heavy Expanded Mobility Tactical Truck|M977 HEMTT]] and M985 HEMTT cargo body trucks. The crane truck, known as a Guided Missile Transporter (GMT), removes spent missile canisters from the launcher and replaces them with fresh missiles. Because the crane nearly doubles the height of the HEMTT when not stowed, crews informally refer to it as the "scorpion tail". A standard M977 HEMTT with a regular-sized crane is sometimes referred to as the Large Repair Parts Transporter (LRPT).{{citation needed|date=December 2022}}

The heart of the Patriot battery is the fire control section, consisting of the AN/MPQ-53 or −65/65A Radar Set (RS), the AN/MSQ-104 or −132 Engagement Control Station (ECS), the OE-349 Antenna Mast Group (AMG), and the EPP-III Electric Power Plant (EPP). The system's missiles are transported on and launched from either the M901 Launching Station (LS), which can carry up to four PAC-2 missiles; the M902 LS, with sixteen PAC-3 missiles; or the M903 LS, which can be configured to carry PAC-2, PAC-3, and MSE/SkyCeptor missiles in various combinations. A Patriot [[battalion]] is also equipped with the Information Coordination Central (ICC), a command station designed to coordinate the launches of a battalion and uplink Patriot to the [[Joint Tactical Information Distribution System|JTIDS]] or [[Multifunctional Information Distribution System|MIDS]] network.{{citation needed|date=December 2022}}

====AN/MPQ-53, -65 and -65A Radar Set====
The AN/MPQ-53/65 Radar Set is a [[passive electronically scanned array]] radar equipped with [[Identification friend or foe|IFF]], electronic counter-countermeasure (ECCM), and [[track-via-missile]] (TVM) guidance subsystems.
The AN/MPQ-53 Radar Set supports PAC-2 units, while the AN/MPQ-65 Radar Set supports PAC-2 and PAC-3 units. The main difference between these two radars is the addition of a second [[travelling-wave tube]] (TWT), which gives the −65 radar increased search, detection, and tracking capability. The radar antenna array consists of over 5,000 elements that "deflect" the radar beam many times per second.

The radar antenna array contains an IFF interrogator subsystem, a TVM array, and at least one "sidelobe canceller" (SLC), which is a small array designed to decrease interference that might affect the radar. Patriot's radar is somewhat unusual in that it is a "detection-to-kill" system, meaning that a single unit performs all search, identification, track, and engagement functions. Most other SAM systems, by contrast, require several different radars to perform all functions necessary to detect and engage targets.

[[File:JASDF Patriot RS(RadarSet) tsuiki 20121028 113836.jpg|thumb|A detailed view of an AN/MPQ-53 Radar Set]]
The beam created by the Patriot's flat phased array radar is comparatively narrow and highly agile compared to that of a moving dish. This characteristic gives the radar the ability to detect small, fast targets like ballistic missiles, or low [[radar cross-section]] targets such as [[stealth aircraft]] or [[cruise missile]]s. The power and agility of Patriot's radar is also highly resistant to countermeasures, including [[electronic countermeasures|ECM]], radar jamming, and use of [[radar warning receiver|RWR]] equipment. Patriot is capable of quickly changing frequencies to resist jamming. However, the radar can suffer from "blind spots."<ref name="DefNews4924" />

[[File:Raytheons GaN-based AESA Radar Prototype.jpg|thumb|An AN/MPQ-65A AESA radar set]]
The Army is planning upgrades to the Patriot system's radar components, including a new digital processor that replaces the one used since the system's introduction. In 2017, the Patriot got a new AN/MPQ-65A [[active electronically scanned array]] (AESA) radar that has greater range and sharper discrimination.<ref>{{cite web |url=http://breakingdefense.com/2015/08/army-missile-defense-must-step-up-its-game-heidi-shyu/ |first=Sydney J.

In October 2017, the Army announced Raytheon's Lower-Tier Air and Missile Defense System (LTAMDS) radar had been selected as the Patriot system's new radar. Unlike the previous radar which could only watch one part of the sky at a time primarily to detect ballistic missiles, the LTAMDS has 360-degree coverage to detect low flying and maneuvering drones and cruise missiles.<ref name="DefNews4924" /> The design has one large main array flanked by two smaller arrays, with the main panel still focused on high-altitude threats and the side panels, which are half the size with twice the power of the previous radar set, able to detect slower threats from considerable distance. Raytheon was awarded a {{US$|383}}{{nbsp}}million contract to build the first six radars to enter service in 2022.<ref>[https://breakingdefense.com/2019/10/ltamds-raytheon-to-build-linchpin-of-army-air-missile-defense/ LTAMDS: Raytheon To Build Linchpin Of Army Air & Missile Defense].

The AN/MSQ-104 or AN/MSQ-132 Engagement Control Station (ECS) is the nerve center of the Patriot firing battery, costing approximately {{US$|6}}{{nbsp}}million per unit.<ref>{{cite web |title=Harpoon database encyclopedia |url=http://www.harpoondatabases.com/encyclopedia/entry1493.aspx |access-date=October 5, 2012 |url-status=dead |archive-url=https://web.archive.org/web/20140730051438/http://www.harpoondatabases.com/encyclopedia/entry1493.aspx |archive-date=July 30, 2014 }} (a database for the computer game [[Harpoon (series)|Harpoon]])</ref>{{Unreliable source?|date=September 2014}} The ECS consists of a shelter mounted on the bed of an [[M939 Truck#Models|M927 5-Ton Cargo Truck]] or on the bed of a [[Light Medium Tactical Vehicle]] (LMTV) cargo truck. The main subcomponents of the ECS are the Weapons Control Computer (WCC), the Data Link Terminal (DLT), the [[Ultra high frequency|UHF]] communications array, the Routing Logic Radio Interface Unit (RLRIU), and the two-person stations that serve as the system's human machine interface. The ECS is air conditioned, pressurized (to resist chemical/biological attack), and shielded against [[electromagnetic pulse]] (EMP) or other such electromagnetic interference. The ECS also contains several [[SINCGARS]] radios to facilitate voice communications.

The WCC is the main computer within the Patriot system. This computer controls the operator interface, calculates missile intercept algorithms, and provides limited fault diagnostics. It was designed as a 24-bit parallel militarized computer with fixed- and floating-point capability, organized in a multiprocessor configuration that operates at a maximum clock rate of {{frequency|6|MHz}}. Compared to modern personal computers, this represents very limited processing power, so the computer has been upgraded several times during Patriot's service life. The latest variant fielded in 2013 has performance improved by several orders of magnitude.

The DLT connects the ECS to Patriot's Launching Stations. It uses either a [[SINCGARS]] radio or fiber optic cables to transmit encrypted data between the ECS and the launchers. Through the DLT, the system operators can remotely emplace, slew or stow launchers, perform diagnostics on launchers or missiles, and fire missiles.

The UHF communications array consists of three UHF radio "stacks" and their associated patching and encrypting equipment. These radios are connected to the antennas of the OE-349 Antenna Mast Group, which are used to create UHF "shots" between sister Patriot batteries and their associated ICC. This creates a secure, real-time data network (known as PADIL, Patriot Data Information Link) that allows the ICC to centralize control of its subordinate firing batteries.

The RLRIU functions as the primary [[Router (computing)|router]] for all data coming into the ECS. The RLRIU gives a firing battery an address on the battalion data network, and sends/receives data from across the battalion. It also "translates" data coming from the WCC to the DLT, facilitating communication with the launchers.

Patriot's crew stations are referred to as Manstation 1 and 3 (MS1 and MS3). These are the stations where Patriot operators interface with the system. The manstations consist of a monochrome (green and black) screen surrounded by various Switch Indicators. Each manstation also has a traditional [[QWERTY]] keyboard and isometric stick, a tiny [[joystick]] that functions much like a [[Personal computer|PC]] [[Mouse (computing)|mouse]]. It is through these switch indicators and the Patriot user interface software that the system is operated. With newer upgrades, the operator's monochrome screen and physical switches have been replaced with two {{convert|30|in|abbr=on}} touchscreen LCDs and a standard keyboard/mouse at both stations.{{citation needed|date=December 2022}}

====OE-349 Antenna Mast Group====
[[File:JASDF Patriot AMG(AntennaMastGroup) ashiya 20161009 100600.jpg|thumb|upright|OE-349/MRC Antenna Mast Group]]
The OE-349 Antenna Mast Group (AMG) is mounted on an M927 5-Ton Cargo Truck. It includes four 4&nbsp;kW antennas in two pairs on remotely controlled masts. Emplacement of the AMG can have no greater than a 0.5-degree roll and a 10-degree crossroll. The antennas can be controlled in azimuth, and the masts can be elevated up to {{convert|100|ft|11|in|m|sp=us}} above ground level. Mounted at the base of each pair of antennas are two high-power amplifiers associated with the antennas and the radios in the co-located shelter.

It is through these antennas that the ECS and ICC send their respective UHF "shots" to create the PADIL network. The polarity of each shot can be changed by adjusting the "feedhorn" to a vertical or horizontal position. This enables a greater chance of communication shots reaching their intended target when terrain obstacles may otherwise obscure the signal.

====EPP-III Electric Power Plant====
[[File:JASDF MIM-104 Patriot PAC-2 Electric Power Plant(Nissan Diesel Big Thumb, 49-0182) left rear view at Kasuga Air Base November 25, 2017.jpg|thumb|left|EPP-III Electric Power Plant vehicle of JSDF]]
The EPP-III Diesel-Electric Power Plant (EPP) is the power source for the ECS and Radar. The EPP consists of two 150&nbsp;kilowatt diesel engines with 400&nbsp;hertz, 3-phase generators that are interconnected through the power distribution unit. The generators are mounted on a trailer or modified [[Heavy Expanded Mobility Tactical Truck|M977 HEMTT]]. Each EPP has two {{convert|100|USgal|L|adj=on}} fuel tanks and a fuel distribution assembly with grounding equipment. Each diesel engine can operate for more than eight hours with a full fuel tank. The EPP delivers its power to the Radar and ECS through cables stored in reels alongside the generators. It powers the AMG via a cable routed through the ECS.

====M901/902/903 Launching Station====
[[File:Ken H. MIM-104 Patriot(PAC-2 & PAC-3) (5092719479).jpg|thumb|upright|M901 (PAC-2) and M902 (PAC-3) Launching Stations]]
The M90x Launching Stations are remotely operated, self-contained units. The ECS controls operation of the launchers through each launcher's DLT, via fiber optic or VHF (SINCGARS) data link.

Integral levelling equipment permits emplacement on slopes of up to 10 degrees. Each launcher is trainable in azimuth and elevates to a fixed, elevated launch position. Precise aiming of the launcher before launch is not necessary; thus, no extra lags are introduced into system reaction time. Each launcher is capable of providing detailed diagnostics to the ECS via the data link.

The launching station contains four major equipment subsystems: the launcher generator set, the launcher electronics module (LEM), the launcher mechanics assembly (LMA), and the launcher interconnection group (LIG). The generator set consists of a 15&nbsp;kW, 400&nbsp;Hz generator that powers the launcher. The LEM is used for the real-time implementation of launcher operations requested via data link from the ECS. The LMA physically erects and rotates the launcher's platform and its missiles. The LIG connects the missiles themselves to the launcher via the Launcher Missile Round Distributor (LMRD).

The first fielded variant was the MIM-104A "Standard". It was optimized solely for engagements against aircraft and had very limited capability against ballistic missiles. It had a range of {{convert|70|km|mi|abbr=on}}, and a speed in excess of Mach 2. The MIM-104B "anti-standoff jammer" (ASOJ) is a missile designed to seek out and destroy [[Electronic countermeasures|ECM]] emitters.

The MIM-104C PAC-2 missile was the first Patriot missile that was optimized for ballistic missile engagements. The GEM series of missiles (MIM-104D/E) are further refinements of the PAC-2 missile. The PAC-3 missile is a new interceptor, featuring a Ka band active radar seeker, employing "hit-to-kill" interception, in contrast to previous interceptors' method of exploding in the vicinity of the target, destroying it with shrapnel, and several other enhancements which dramatically increase its lethality against ballistic missiles. The specific information for these different kinds of missiles are discussed in the "[[#Variants|Variants]]" section.

The first seven of these are in the larger PAC-2 configuration of a single missile per canister, of which four can be placed on a launcher. PAC-3 missile canisters contain four missiles, so that sixteen rounds can be placed on a launcher. The missile canister serves as both the shipping and storage container and the launch tube. Patriot missiles are referred to as "certified rounds" as they leave the factory, and additional maintenance is not necessary on the missile prior to it being launched.

The PAC-2 missile is {{convert|5.8|m|ftin}} long, weighs about {{convert|900|kg|lb}}, and is propelled by a solid-fueled rocket motor.

====Patriot missile design====
The PAC-2 family of missiles all have a fairly standard design, the only differences between the variants being certain internal components. They consist of (from front to rear) the [[radome]], guidance section, warhead section, propulsion section, and control actuator section.

The radome is made of slip cast fused silica approximately {{convert|16.5|mm}} thick, with a nickel alloy tip, and a composite base attachment ring bonded to the slip cast fused silica and protected by a molded silicone rubber ring. The radome provides an aerodynamic shape for the missile and [[microwave]] window and thermal protection for the [[Radio frequency|RF]] seeker and electronic components.

The Patriot guidance section consists primarily of the modular digital airborne guidance system (MDAGS). The MDAGS consists of a modular midcourse package that performs all of the required guidance functions from launch through midcourse and a terminal guidance section. The TVM seeker is mounted on the guidance section, extending into the radome.
The seeker consists of an antenna mounted on an inertial platform, antenna control electronics, a receiver, and a transmitter. The Modular Midcourse Package (MMP), which is located in the forward portion of the warhead section, consists of the navigational electronics and a missile-borne computer that computes the guidance and autopilot algorithms and provides steering commands according to a resident computer program.

The warhead section, just aft of the guidance section, contains the [[proximity fuze]]d warhead, safety-and-arming device, fuzing circuits and antennas, link antenna switching circuits, auxiliary electronics, inertial sensor assembly, and signal data converter.

The propulsion section consists of the [[rocket]] motor, external heat shield, and two external conduits. The rocket motor includes the case, nozzle assembly, propellant, liner and insulation, pyrogen igniter, and propulsion arming and firing unit. The casing of the motor is an integral structural element of the missile airframe. It contains a conventional, casebonded solid rocket propellant.

The Control Actuator Section (CAS) is at the aft end of the missile. It receives commands from the missile autopilot and positions the fins. The missile fins steer and stabilize the missile in flight. A fin [[Servomechanism|servo]] system positions the fins. The fin servo system consists of [[hydraulic]] actuators and valves and an electrohydraulic power supply. The electrohydraulic power consists of a battery, motor pump, oil reservoir, gas pressure bottle, and accumulator.

===MIM-104A===
Patriot was first introduced with a single missile type: the MIM-104A. This was the initial "Standard" missile, still known as "Standard" today. In Patriot's early days, the system was used exclusively as an anti-aircraft weapon, with no capability against ballistic missiles. This was remedied during the late 1980s when Patriot received its first major system overhaul with the introduction of the Patriot Advanced Capability missile and concurrent system upgrades.

==={{Anchor|MIM-104B|PAC-1}} MIM-104B (PAC-1)===
Patriot Advanced Capability (PAC-1), known today as the PAC-1 upgrade, was a software-only upgrade. The most significant aspects of this upgrade were changing the way the radar searched and the way the system defended its assets. Instead of searching low to the horizon, the top of the radar's search angle was lifted to near vertical (89 degrees) from the previous angle of 25 degrees. This was done as a counter to the steep parabolic trajectory of inbound ballistic missiles. The search beams of the radar were tightened, and while in "TBM search mode" the "flash," or the speed at which these beams were shot out, was increased significantly.

While this increased the radar's detection capability against the ballistic missile threat set, it decreased the system's effectiveness against traditional atmospheric targets, as it reduced the detection range of the radar as well as the number of "flashes" at the horizon. Because of this, it was necessary to retain the search functions for traditional atmospheric threats in a separate search program, which could be easily toggled by the operator based on the expected threat.

The ballistic missile defense capability changed the way Patriot defended targets. Instead of being used as a system to defend a significant area against enemy air attack, it was now used to defend much smaller "point" targets, which needed to lie within the system's TBM "footprint". The footprint is the area on the ground that Patriot can defend against inbound ballistic missiles.

During the 1980s, Patriot was upgraded in relatively minor ways, mostly via its software. The most significant of these was a special upgrade to discriminate and intercept artillery rockets in the vein of the [[multiple rocket launcher]], which was seen as a significant threat from North Korea. This feature has not been used in combat and has since been deleted from [[United States Army|U.S. Army]] Patriot systems, though it remains in South Korean systems. Another upgrade the system saw was the introduction of another missile type, designated MIM-104B and called "anti stand-off jammer" (ASOJ) by the Army. This variant is designed to help Patriot engage and destroy [[radar jamming and deception|ECM]] aircraft at standoff ranges. It works similar to an [[anti-radiation missile]] in that it flies a highly [[lofted trajectory]] and then locates, [[home-on-jam|homes in on]], and destroys the most significant emitter in an area designated by the operator.

==={{Anchor|MIM-104C|PAC-2}} MIM-104C (PAC-2)===
During the late 1980s, tests began to indicate that, although Patriot was certainly capable of intercepting inbound ballistic missiles, it was questionable whether the MIM-104A/B missile was capable of destroying them reliably. This necessitated the introduction of the PAC-2 missile and system upgrade.

For the system, the PAC-2 upgrade was similar to the PAC-1 upgrade. Radar search algorithms were further optimized, and the beam protocol while in "TBM search" was further modified. PAC-2 saw Patriot's first major missile upgrade, with the introduction of the MIM-104C, or PAC-2 missile. This missile was optimized for ballistic missile engagements. Major changes to the PAC-2 missile were the size of the projectiles in its blast-fragmentation warhead, changed from around 2&nbsp;grams to around 45&nbsp;grams, and the timing of the [[pulse-Doppler radar]] fuze, which was optimized for high-speed engagements, though it retained its old algorithm for aircraft engagements if necessary.

Engagement procedures were optimized, changing the method of fire the system used to engage ballistic missiles. Instead of launching two missiles in an almost simultaneous salvo, a brief delay between 3 and 4 seconds was added, in order to allow the second missile launched to discriminate a ballistic missile warhead in the aftermath of the explosion of the first.

PAC-2 was first tested in 1987 and reached Army units in 1990, just in time for deployment to the Middle East for the [[Gulf War|Persian Gulf War]]. It was there that Patriot was first regarded as a successful ABM system and proof that ballistic missile defense was indeed possible. The complete study on its effectiveness remains classified.

In April 2013, [[Raytheon]] received U.S. Army approval for a second recertification, extending the operational life of the worldwide inventory of Patriot missiles from 30 to 45 years.<ref>{{cite web |url=http://www.deagel.com/news/US-Army-to-Extend-Patriot-Missiles-Service-Life-to-45-Years_n000011365.aspx |title=US Army to Extend Patriot Missiles Service Life to 45 Years |website=Deagel.com |date=April 1, 2013 |access-date=April 1, 2013 |archive-url=https://web.archive.org/web/20130518125324/http://www.deagel.com/news/US-Army-to-Extend-Patriot-Missiles-Service-Life-to-45-Years_n000011365.aspx |archive-date=May 18, 2013 |url-status=dead }}</ref><ref>{{cite web|url=https://raytheon.mediaroom.com/index.php?s=43&item=2302|title=Raytheon: Raytheon's Patriot missiles receive US Army service life extension - Apr 1, 2013|website=Raytheon News Release Archive}}</ref>

==={{Anchor|MIM-104D|GEM}} MIM-104D (PAC-2/GEM)===
There were more upgrades to PAC-2 systems throughout the 1990s and into the 21st century, mostly centering on software. The PAC-2 missiles were modified significantly—four separate variants became known collectively as '''guidance enhanced missiles (GEM)'''.

The main upgrade to the original GEM missile was a new, faster proximity fuzed warhead. Tests had indicated that the fuze on the original PAC-2 missiles were detonating their warheads too late when engaging ballistic missiles with an extremely steep ingress, and as such it was necessary to shorten this fuze delay. The GEM missile was given a new "low [[Noise (radio)|noise]]" seeker head designed to reduce interference in front of the missile's radar seeker, and a higher performance seeker designed to better detect low [[radar cross-section]] targets.<ref name="M104">{{cite web |url=http://www.designation-systems.net/dusrm/m-104.html |title=Raytheon MIM-104 Patriot |first=Andreas |last=Parsch |website=Directory of U.S. Military Rockets and Missiles |access-date=September 27, 2014 |archive-url=https://web.archive.org/web/20150411014329/http://www.designation-systems.net/dusrm/m-104.html |archive-date=April 11, 2015 |url-status=dead }}</ref> The GEM was used extensively in [[2003 invasion of Iraq|Operation Iraqi Freedom]] (OIF), during which air defense was highly successful.<ref>{{cite web |url=http://www.operationtelic.co.uk/documents/32aamdc-oif-patriot-sep03.pdf |title=32nd AAMDC: Operation Iraqi Freedom |website=OperationTelic.co.uk |date=September 2003 |access-date=September 27, 2014 |quote=9 of 9 vs TBM with no loss of life or equipment. |archive-url=https://web.archive.org/web/20140606040157/http://operationtelic.co.uk/documents/32aamdc-oif-patriot-sep03.pdf |archive-date=June 6, 2014 |url-status=dead }}</ref>

==={{Anchor|MIM-104E|GEM+|GEM-T}} MIM-104E (PAC-2/GEM+)===
Just prior to OIF, it was decided to further upgrade the GEM and PAC-2 missiles. This upgrade program produced missiles known as the GEM-T and the GEM-C, the "T" designator referring to tactical ballistic missiles, and the "C" designator referring to cruise missiles. These missiles were both given a totally new nose section, which was designed specifically to be more effective against low altitude, low RCS targets like cruise missiles. The GEM-T was given a new fuze which was further optimized against ballistic missiles and a new low noise oscillator which increases the seeker's sensitivity to low radar cross-section targets. The GEM-C is the upgraded version of the GEM, and the GEM-T is the upgraded version of the PAC-2. The GEM+ entered service in November 2002.<ref name=armytechnology-patriot>{{Cite web|url=https://www.army-technology.com/projects/patriot/|title=Patriot Missile Long-Range Air-Defence System|website=army-technology.com|access-date=December 22, 2022}}</ref>

<!-- This section is linked from [[Arrow missile]] -->
[[File:Maintenance check on a Patriot missile.jpg|thumb|A PAC-3 missile launcher, note the four missiles in each canister]]
The PAC-3 upgrade is a significant upgrade to nearly every aspect of the system. It took place in three stages deployed in 1995, 1996 and 2000, and units were designated Configuration 1, 2, or 3.

New software update known as PDB 5 (PDB standing for "post deployment build") was released in 1999 with initial support for Configuration-3 ground units and PAC-3 missiles. The system itself saw another upgrade of its WCC, and the communication setup was given a complete overhaul. Due to this upgrade, PAC-3 operators can now see, transmit, and receive tracks on the [[Link 16]] Command and Control (C2) network using a Class 2M Terminal or [[Multifunctional Information Distribution System|MIDS LVT]] Radio. This capability greatly increases the situational awareness of Patriot crews and other participants on the Link 16 network that are able to receive the Patriot local air picture.

The software can now conduct a tailored TBM search, optimizing radar resources for search in a particular sector known to have ballistic missile activity, and can support a "keepout altitude" to ensure ballistic missiles with chemical warheads or early release [[submunition]]s (ERS) are destroyed at a certain altitude. For Configuration 3 units, the Patriot radar was completely redesigned, adding another [[traveling wave tube]] (TWT) that increased the radar's search, detection, tracking, and discrimination abilities. The new radar is designated AN/MPQ-65. It is capable, among other things, of discriminating whether an aircraft is crewed and which of multiple reentering ballistic objects are carrying ordnance.

The PAC-3 upgrade carried with it a new missile design, nominally known as MIM-104F and called PAC-3 by the Army.<ref name="auto3">{{cite book |url=http://www.msl.army.mil/Documents/peoWeaponSystems.pdf |chapter=PATRIOT MIM-104F Advanced Capability – 3 (PAC-3) Missile |publisher=Program Executive Office Missiles and Space |title=Weapon Systems Book |date=2012 |access-date=September 27, 2014 |page=97 |url-status=dead |archive-url=https://web.archive.org/web/20141016125635/http://www.msl.army.mil/Documents/peoWeaponSystems.pdf |archive-date=October 16, 2014 }}</ref> First deployed in 1997, the PAC-3 missile evolved from the [[Strategic Defense Initiative]]'s [[ERINT]] missile, and so it is dedicated almost entirely to the anti-ballistic missile mission. Due to miniaturization, a single canister can hold four PAC-3 missiles, as opposed to one PAC-2 missile per canister. The PAC-3 missile is more maneuverable than previous variants, due to 180 tiny pulse solid propellant rocket motors mounted in the forebody of the missile, called Attitude Control Motors, or ACMs, which serve to fine align the missile trajectory with its target to achieve hit-to-kill capability.<ref name="auto3"/><ref name=howstuffworks>{{cite web |title=How Patriot Missiles Work |date=March 10, 2022 |url=https://science.howstuffworks.com/patriot-missile.htm |last1=Brain |last2=Gleim |first1=Marshall| first2=Sarah |website=science.howstuffworks.com |access-date=May 8, 2023}}</ref>

[[File:JASDF MIM-104 Patriot PAC-3 Missile(dummy model) side thruster at Hamamatsu Air Base October 20, 2019.jpg|thumb|right|Attitude control motors]]
The most significant upgrade to the PAC-3 missile is the addition of a [[Ka band|K<sub>a</sub> band]] [[Active radar homing|active radar]] seeker. This allows the missile to drop its uplink to the system and acquire its target itself in the terminal phase of its intercept, which improves the reaction time of the missile against a fast-moving ballistic missile target. The PAC-3 missile is accurate enough to select, target, and home in on the warhead portion of an inbound ballistic missile. The active radar gives the warhead a "hit-to-kill" ([[kinetic kill vehicle]]) capability that eliminates the need for a traditional proximity-fused warhead. The missile still has a small explosive warhead, called a ''lethality enhancer'', a warhead which launches 24 low-speed [[tungsten]] fragments in a radial direction to make the missile cross-section greater and enhance the [[kill probability]]. This greatly increases the lethality against ballistic missiles of all types.<ref name="auto3"/>

The PAC-3 upgrade has effectively quintupled the "footprint" that a Patriot unit can defend against ballistic missiles of all types, and has considerably increased the system's lethality and effectiveness against ballistic missiles. It has increased the scope of ballistic missiles that Patriot can engage, which now includes several intermediate ranges. However, despite its increases in ballistic missile defense capabilities, the PAC-3 missile has a shorter range and a smaller explosive warhead compared to older Patriot missiles, making it a less capable interceptor of atmospheric aircraft and [[air-to-surface missile]]s.

Since the PAC-3 ground units can control both M901 PAC-2 launchers and M902/M903 PAC-2/PAC-3 launchers, Patriot batteries employ a mix of PAC-3 hit-to-kill active missiles and PAC-2 GEM-T blast fragmentation warhead semi-active missiles to counter both ballistic missile and aircraft threats.<ref>{{cite web |title=FY14 ARMY PROGRAMS: Patriot Advanced Capability-3 (PAC-3) |url=https://www.dote.osd.mil/Portals/97/pub/reports/FY2014/army/2014patriot.pdf |website=dote.osd.mil |access-date=July 11, 2022}}</ref><ref>{{cite web | url=http://armscontrol.org/act/2002-07/pac-3-production-continue-despite-program-shortcomings | title=PAC-3 Production to Continue Despite Program Shortcomings &#124; Arms Control Association }}</ref> While the PAC-2 is able to intercept targets up to an altitude of {{cvt|20|km|ft|abbr=on}}, the PAC-3 can destroy incoming missiles at an altitude of {{cvt|40|km|ft|abbr=on}}.<ref>[https://www.defensenews.com/global/asia-pacific/2022/06/06/south-korea-to-buy-more-patriot-missiles-upgrade-launchers/ South Korea to buy more Patriot missiles, upgrade launchers].

According to Lockheed Martin, PAC-3 CRI can be quad-packed into a VLS cell; though the Navy is considering the single-packed PAC-3 MSE version as its replacement for the SM-2 missile system, PAC-3 CRI is considered a potential follow-on project offering greater magazine depth as a tradeoff for decreased performance compared to PAC-3 MSE.<ref name=":3" />

==Patriot battalion==
In the [[United States Army|U.S. Army]], the Patriot System is designed around the [[battalion]] echelon. A Patriot battalion consists of a headquarters battery, which includes the Patriot ICC and its operators, a maintenance company, and between four and six "[[Artillery battery|line batteries]]," which are the actual launching batteries that employ the Patriot systems. Each line battery consists of (nominally) six launchers{{citation needed|date=December 2022}} and three or four [[platoon]]s: Fire Control platoon, Launcher platoon, and a Headquarters/Maintenance platoon - either a single platoon or separated into two separate units, at the battery commander's discretion.

The Fire Control platoon is responsible for operating and maintaining the "big 4," radar, the engagement control station, the antenna mast group, and the electric power plant. The launcher platoon operates and maintains the launchers. The Headquarters/Maintenance platoon(s) provide the battery with maintenance support and a headquarters section. The Patriot line battery is commanded by a [[Captain (OF-2)|captain]] and usually consists of between 70 and 90 soldiers. The Patriot battalion is commanded by a [[lieutenant colonel]] and can include as many as 600 soldiers.

Once deployed, the system requires a crew of only three individuals to operate. The Tactical Control Officer (TCO), usually a lieutenant, is responsible for the operation of the system. The TCO is assisted by the Tactical Control Assistant (TCA). Communications are handled by the third crewmember, the communications system specialist. A "hot-crew" composed of an NCOIC (usually a Sergeant) and one or more additional launcher crew members is on-hand to repair or refuel launching stations. A reload crew is on standby to replace spent canisters after missiles are launched. The ICC crew is similar to the ECS crew at the battery level, except its operators are designated as the Tactical Director (TD) and the Tactical Director Assistant (TDA).

Patriot battalions prefer to operate in a centralized fashion, with the ICC controlling the launches of all of its subordinate launching batteries through the secure UHF PADIL communications network.

The dismounted Patriot ICC (D-PICC) is a set of equipment which is composed of the same hardware as that at battalion level, but which distributes command and control over the launching batteries, which allows the batteries to disperse over a wider geographic area, with no loss of command and control. D-PICC is deploying to Pacific Command first.<ref>{{cite web|url=https://www.dvidshub.net/news/269249/japan-patriot-battalion-fields-first-operational-dismounted-patriot-information-coordination-central-d-picc|title=Japan Patriot Battalion fields first operational Dismounted Patriot Information Coordination Central (D-PICC)|access-date=April 30, 2018|archive-url=https://web.archive.org/web/20180430114753/https://www.dvidshub.net/news/269249/japan-patriot-battalion-fields-first-operational-dismounted-patriot-information-coordination-central-d-picc|archive-date=April 30, 2018|url-status=live}}</ref><ref>{{cite web|url=http://www.fi-aeroweb.com/Defense/Budget-Data/FY2017/LTAMD-ARMY-PROC-FY2017.pdf|title=D-PICC line item in the 2016 Exhibit P-40, Budget Line Item Justification: PB 2017 Army, February 2016|access-date=April 30, 2018|archive-url=https://web.archive.org/web/20171028210113/http://fi-aeroweb.com/Defense/Budget-Data/FY2017/LTAMD-ARMY-PROC-FY2017.pdf|archive-date=October 28, 2017|url-status=dead}}</ref>

===Operation===
==== Engaging a single aircraft ====
Following is the process a PAC-2 firing battery uses to engage a single target (an aircraft) with a single missile:{{Citation needed|reason=Reliable source needed for the described CONOPS|date=December 2017}}

# A hostile aircraft is detected by the AN/MPQ-65 Radar. The radar examines the track's size, speed, altitude, and heading, and decides whether or not it is a legitimate track or "clutter" created by RF interference.
# If the track is classified by the radar as an aircraft, in the AN/MSQ-104 Engagement Control Station, an unidentified track appears on the screen of the Patriot operators. The operators examine the speed, altitude and heading of the track. Additionally, the IFF subsystem "pings" the track to determine if it has any IFF response.
# Based on many factors, including the track's speed, altitude, heading, IFF response, or its presence in "safe passage corridors" or "missile engagement zones," the ECS operator, the TCO (tactical control officer), makes an ID recommendation to the ICC operator, the TD (tactical director).
# The TD examines the track and decides to certify that it is hostile. Typically, the engagement authority for Patriot units rests with the Regional or Sector Air Defense Commander (RADC/SADC), who will be located either on a [[US Navy|U.S. Navy]] [[guided missile cruiser]] or on a [[USAF]] [[E-3 Sentry|AWACS]] aircraft. A Patriot operator (called the "ADAFCO" or Air Defense Artillery Fire Control Officer) is colocated with the RADC/SADC to facilitate communication to the Patriot battalions.
# The TD contacts the ADAFCO and correlates the track, ensuring that it is not a friendly aircraft.
# The ADAFCO obtains the engagement command from RADC/SADC, and delegates the engagement back down to the Patriot battalion.
# Once the engagement command is received, the TD selects a firing battery to take the shot and orders them to engage.
# The TCO instructs the TCA to engage the track. The TCA brings the system's launchers from "standby" into "operate".
# The TCA presses the "engage" switch indicator. This sends a signal to the selected launcher and fires a missile selected automatically by the system.
# The AN/MPQ-65 Radar, which has been continuously tracking the hostile aircraft, "acquires" the just-fired missile and begins feeding it interception data. The Radar also "illuminates" the target for the missile's [[semi-active radar]] seeker.
# The monopulse receiver in the missile's nose receives the reflection of illumination energy from the target. The [[track-via-missile]] uplink sends this data through an antenna in the missile's tail back to the AN/MPQ-65 set. In the ECS, computers calculate the maneuvers that the missile should perform in order to maintain a trajectory to the target and the TVM uplink sends these to the missile.
# Once in the vicinity of the target, the missile detonates its proximity fused warhead.

==== Engaging a ballistic missile ====
Following is the process a PAC-3 firing battery uses to engage a single [[tactical ballistic missile]] with two PAC-3 missiles:{{Citation needed|reason=Reliable source needed for the described CONOPS|date=December 2017}}

# A missile is detected by the AN/MPQ-65 radar. The radar reviews the speed, altitude, behavior, and radar cross-section of the target. If this data lines up with the discrimination parameters set into the system, the missile is presented on the screen of the operator as a ballistic missile target.
# In the AN/MSQ-104 Engagement Control Station, the TCO reviews the speed, altitude, and trajectory of the track and then authorizes engagement. Upon authorizing engagement, the TCO instructs his TCA to bring the system's launchers into "operate" mode from "standby" mode. The engagement will take place automatically at the moment the computer defines the parameters that ensure the highest probability of kill.
# The system computer determines which of the battery's launchers have the highest probability of kill and selects them to fire. Two missiles are launched 4.2 seconds apart in a "ripple".
# The AN/MPQ-65 radar continues tracking the target and uploads intercept information to the PAC-3 missiles which are now outbound to intercept.
# Upon reaching its terminal homing phase, the Ka band active radar seeker in the nose of the PAC-3 missile acquires the inbound ballistic missile. This radar selects the radar return most likely to be the warhead of the incoming missile and directs the interceptor towards it.
# The ACMs (attitude control motors) of the PAC-3 missile fire to precisely align the missile on the interception trajectory.
# The interceptor flies straight through the warhead of the inbound ballistic missile, detonating it and destroying the missile.
# The second missile locates any debris which may be a warhead and attacks in a similar manner.

==Operational history==
===Persian Gulf War (1991)===

====Trial by fire====
Prior to [[Gulf War|the First Gulf War]], ballistic missile defense was an unproven concept in war. During Operation Desert Storm, in addition to its anti-aircraft mission, the Patriot was assigned to shoot down incoming Iraqi [[Scud]] or [[Al Hussein (missile)|Al Hussein]] short range ballistic missiles launched at Israel and [[Saudi Arabia]]. The first combat use of Patriot occurred January 18, 1991, when it engaged what was later found to be a computer glitch.<ref name="DACS Working Paper">{{cite web |url=http://kms1.isn.ethz.ch:80/serviceengine/Files/ISN/19691/ipublicationdocument_singledocument/600a9352-1c22-46c3-870d-f60dc987403e/en/Casualties_Scud_Attacks.pdf |first1=George N. |last1=Lewis |first2=Steve |last2=Fetter |first3=Lisbeth |last3=Gronlund|author3-link= Lisbeth Gronlund |title=Casualties and Damage from Scud Attacks in the 1991 Gulf War |date=March 1993 |website=Massachusetts Institute of Technology Defense and Arms Control Studies Program |access-date=May 11, 2010 |archive-url=https://web.archive.org/web/20160102043600/http://kms1.isn.ethz.ch/serviceengine/Files/ISN/19691/ipublicationdocument_singledocument/600a9352-1c22-46c3-870d-f60dc987403e/en/Casualties_Scud_Attacks.pdf |archive-date=January 2, 2016 |url-status=dead}}</ref> There were actually no Scuds fired at Saudi Arabia on January 18.<ref name="United Kingdom Ministry of Defence">{{cite web |url=http://www.gulflink.osd.mil/al_jub_ii/al_jub_ii_refs/n50en122/british_mod.htm |title=A Review of the Suggested Exposure of UK Forces to Chemical Warfare Agents in Al Jubayl During the Gulf Conflict |date=January 2000 |website=Office of the Special Assistant for the Gulf War Illnesses |access-date=May 11, 2010 |archive-url=https://web.archive.org/web/20101110095650/http://www.gulflink.osd.mil/al_jub_ii/al_jub_ii_refs/n50en122/british_mod.htm |archive-date=November 10, 2010 |url-status=dead }}</ref> This incident was widely misreported as the first successful interception of an enemy ballistic missile in history.

Throughout the war, Patriot missiles attempted engagement of over 40 hostile ballistic missiles. The success of these engagements, and in particular how many of them were real targets, is still controversial.

====Failure at Dhahran====
On February 25, 1991, an Iraqi [[Al Hussein (missile)|Al Hussein Scud]] missile hit the barracks in [[Dhahran]], [[Saudi Arabia]], killing 28 soldiers from the U.S. Army's [[14th Quartermaster Detachment]].<ref name=NYT>{{cite news |last=Apple |first=R.

Due to the missile's speed this was equivalent to a miss distance of 600 meters.

The radar system had successfully detected the Scud and predicted where to look for it next. However, the timestamps of the two radar pulses being compared were converted to [[Floating-point number|floating point]] differently: one correctly, the other introducing an error proportionate to the operation time so far (100 hours) caused by the truncation in a 24-bit fixed-point register. As a result, the difference between the pulses was wrong, so the system looked in the wrong part of the sky and found no target. With no target, the initial detection was assumed to be a spurious track and the missile was removed from the system.<ref>{{cite news |url=https://www.latimes.com/archives/la-xpm-1991-02-26-mn-1889-story.html |first1=Bob |last1=Drogin |first2=Patt |last2=Morrison |title=Iraqi Missile Slams Into GIs' Barracks; 27 Killed : Scud attack: 98 are hurt in the deadliest such strike of the war.

====Success rate vs. accuracy====
{{see also|Theodore Postol#Patriot missiles in Operation Desert Storm}}
On February 15, 1991, President [[George H. W. Bush]] traveled to Raytheon's Patriot manufacturing plant in [[Andover, Massachusetts]], during the Gulf War. He declared, the "Patriot is 41 for 42: 42 Scuds engaged, 41 intercepted!"<ref>{{cite web |url=http://bushlibrary.tamu.edu/research/public_papers.php?id=2711&year=1991&month=2 |title=Remarks to Raytheon Missile Systems Plant Employees in Andover, Massachusetts |first=George H.

On April 7, 1992, [[Theodore Postol]] of MIT, and Reuven Pedatzur of [[Tel Aviv University]] testified before a [[U.S. House of Representatives|House Committee]] claiming that, according to their independent analysis of video tapes, the Patriot system had a success rate of below 10%, and perhaps even a zero success rate.<ref name="fas_Postol">{{cite web |url= http://www.fas.org/spp/starwars/congress/1992_h/h920407p.htm |title= Optical Evidence Indicating Patriot High Miss Rates During the Gulf War |first=Theodore A. |last= Postol |website=Federation of American Scientists |date= April 7, 1992 |access-date=January 29, 2008 |archive-url= https://web.archive.org/web/20090415122817/http://www.fas.org/spp/starwars/congress/1992_h/h920407p.htm |archive-date= April 15, 2009}}</ref><ref name="fas_Pedatzur">{{cite web |url= http://www.fas.org/spp/starwars/congress/1992_h/h920407r.htm |title=The Israeli Experience Operating Patriot in the Gulf War |first=Reuven |last=Pedatzur |website= Federation of American Scientists |date=April 7, 1992 |access-date=June 13, 2009 |archive-url= https://web.archive.org/web/20141209235250/http://www.fas.org/spp/starwars/congress/1992_h/h920407r.htm |archive-date=December 9, 2014}}</ref>

On April 7, 1992, Charles A. Zraket of [[Harvard Kennedy School]] and [[Peter Zimmerman]] of the [[Center for Strategic and International Studies]], a [[think tank]] funded by the United States government and Raytheon, testified about the calculation of success rates and accuracy in Israel and Saudi Arabia and discounted many of the statements and methodologies in Postol's report.<ref name="fas_Zraket">{{cite web |url=http://www.fas.org/spp/starwars/congress/1992_h/h920407m.htm |title=Testimony of Charles A.

* Success rate – the percentage of Scuds destroyed or deflected to unpopulated areas
* Accuracy – the percentage of hits out of all the Patriots fired

In accordance with the standard firing doctrine, on average four Patriots were launched at each incoming Scud{{snd}} in Saudi Arabia an average of three Patriots were fired. The large number of missiles fired suggests low confidence in individual missiles and that a higher rate of successful interceptions was achieved through brute force. For example, if a Patriot has a 50% individual success rate, two missiles will intercept 75% of the time, and three will intercept 87.5% of the time. Only one has to hit for a successful interception, but this does not mean that the other missiles would not also have hit.

The Iraqi redesign of the Scuds also played a role. Iraq had redesigned its Scuds by removing weight from the warhead to increase speed and range, but the changes weakened the missile and made it unstable during flight, creating a tendency for the Scud to break up during its descent from [[near space]]. This presented a larger number of targets as it was unclear which piece contained the warhead.

According to the Zraket testimony, there was a lack of [[High speed photography|high quality photographic equipment]] necessary to record the interceptions of targets. Therefore, Patriot crews recorded each launch on [[standard-definition]] videotape, which was insufficient for detailed analysis. Damage assessment teams videotaped the Scud debris that was found on the ground. Crater analysis was then used to determine if the warhead was destroyed before the debris crashed or not. Part of the reason for the 30% improvement in success rate in Saudi Arabia compared to Israel is that the Patriot merely had to push the incoming Scud missiles away from military targets in the desert or disable the Scud's warhead in order to avoid casualties, while in Israel the Scuds were aimed directly at cities and civilian populations.

The Saudi Government also censored any reporting of Scud damage by the Saudi press. The Israeli Government did not institute the same type of censorship. Patriot's success rate in Israel was examined by the [[Israel Defense Forces]] (IDF) who did not have a political reason to play up Patriot's success rate.{{Citation needed|date=October 2017}} The IDF counted any Scud that exploded on the ground, regardless of whether or not it was diverted, as a failure for the Patriot. Meanwhile, the U.S. Army, which had many reasons to support a high success rate for Patriot, examined the performance of Patriot in Saudi Arabia.

Both testimonies state that part of the problems stem from its original design as an anti-aircraft system. Patriot was designed with [[proximity fuze|proximity fuse]]d warheads, which are designed to explode immediately prior to hitting a target spraying shrapnel out in a fan in front of the missile, either destroying or disabling the target. These missiles were fired at the target's center of mass. With aircraft this was fine, but considering the much higher speeds of tactical ballistic missiles, as well as the location of the warhead, usually in the nose, Patriot most often hit closer to the tail of the Scud due to the delay present in the [[proximity fuse]]d warhead, thus not destroying the missile's warhead and allowing it to fall to earth.

In response to the testimonies and other evidence, the staff of the House Government Operations Subcommittee on Legislation and National Security reported, "The Patriot missile system was not the spectacular success in the Persian Gulf War that the American public was led to believe. There is little evidence to prove that the Patriot hit more than a few [[Scud]] missiles launched by Iraq during the Gulf War, and there are some doubts about even these engagements. The public and the [[United States Congress]] were misled by definitive statements of success issued by administration and Raytheon representatives during and after the war."<ref>{{cite web |url= http://www.fas.org/spp/starwars/docops/operate.htm |title=Star Wars – Operations |website=Federation of American Scientists |access-date=September 27, 2014 |archive-url=https://web.archive.org/web/20141209210030/http://www.fas.org/spp/starwars/docops/operate.htm |archive-date=December 9, 2014}}</ref>

====Patriot operations in the Russo-Ukrainian War====
Patriot has had a successful track record in Ukraine during the [[Russo-Ukrainian War]], successfully intercepting a wide range of Russian weaponry and aircraft.<ref name=DefNews4924 /> It has shot down Russian aircraft like Su-34 fighters flying nearly 100 miles away, and intercepted missiles as far as 130 miles away, according to defense NGO reports.<ref name="DefNews4924" /> During October 2023, under a program called "[[FrankenSAM]]" Western and Soviet air defence technologies are being combined in Ukraine. One of three programs involves a Ukrainian radar guiding a Patriot missile.

===Demands on Patriot systems===

Including the United States, 18 countries operate Patriot missile systems. Outside the US, only Japan's [[Mitsubishi Heavy Industries]] appears to build Patriot missiles, under licence from various US companies. This has led to a demand on the US Army. Patriot batteries are the most deployed units in the US Army by early 2021. Some units have had a 6-month deployment extended up to 15 months.<ref name=DefNews4924 /><ref>{{cite web|url= https://missilethreat.csis.org/system/patriot/|publisher= CSIS |title= Patriot|date=August 23, 2023 |access-date=December 30, 2023}}</ref><ref name="Mariko Oi">{{cite web|url= https://www.bbc.com/news/world-asia-67798740|publisher=BBC |title= Japan to send Patriot missiles to US which may aid Ukraine|author=Mariko Oi|date=December 22, 2023 |access-date=December 30, 2023}}</ref><ref name="JOSEPH TREVITHICK">{{cite web|url= https://www.thedrive.com/the-war-zone/inadequate-u-s-patriot-missile-force-size-highlighted-by-middle-east-crisis|publisher= The War Zone|title= Inadequate U.S. Patriot Missile Force Size Highlighted By Middle East Crisis|author= JOSEPH TREVITHICK|author2= TYLER ROGOWAY|date= October 30, 2023|access-date= December 30, 2023|archive-date= December 30, 2023|archive-url= https://web.archive.org/web/20231230111129/https://www.thedrive.com/the-war-zone/inadequate-u-s-patriot-missile-force-size-highlighted-by-middle-east-crisis|url-status= dead}}</ref> The missile is currently being used in active service in Saudi Arabia.<ref>{{cite web|url= https://www.timesofisrael.com/liveblog_entry/saudi-arabia-intercepted-houthi-missile-headed-toward-israel-report/|publisher=Times of Israel|title= Saudi Arabia intercepted Houthi missile headed toward Israel — report|author=JACOB MAGID|date=October 24, 2023 |access-date=December 30, 2023}}</ref> In active use by the [[Israeli Defence Force|IDF]] in the "southern Negev desert".<ref>{{cite web|url= https://www.reuters.com/world/middle-east/israeli-military-says-unidentified-drone-hits-southern-city-eilat-2023-11-09/|publisher=Reuters|title= Israel strikes Syria after drone hits southern Eilat city - Israeli military|author=Emily Rose|author2=Jonathan Saul |date=November 10, 2023 |access-date=December 30, 2023}}</ref> The Patriot missile batteries are also seeing active service in Ukraine, where there are three batteries in service.<ref>{{Cite news |date=December 29, 2023 |title=Nuclear warfighter: Key characteristics of Russian Tu-22M3 bomber and Kh-22 'blind' missiles |language=en |work=MSN|url=https://www.msn.com/en-ca/news/world/nuclear-warfighter-key-characteristics-of-russian-tu-22m3-bomber-and-kh-22-blind-missiles/ar-AA1mdgGT|author1= Danylo Kramarenko|author2= Daria Shekina|publisher=MSN|access-date=December 30, 2023}}</ref> To refill US stockpiles, Japan has modified its export rules to allow export of missiles to the United States.
