The '''FV101 Scorpion''' is a British armoured [[reconnaissance vehicle]] and [[light tank]]. It was the lead vehicle and the fire support type in the [[Combat Vehicle Reconnaissance (Tracked)]], CVR(T), family of seven armoured vehicles. Manufactured by [[Alvis Car and Engineering Company|Alvis]], it was introduced into service with the [[British Army]] in 1973 and was withdrawn in 1994.<ref>{{cite web |url=https://www.militarytrader.com/military-vehicles-news/the-scorpion-cvrt |title=MV Spotlight: The Scorpion CVR(T)|work=Military Trader |date=21 May 2021 }}</ref><ref>{{Cite web |url=http://www.historynet.com/fv101-scorpion-keeping-the-light-tank-relevant.htm|title=FV101 Scorpion: Keeping the Light Tank Relevant |website=HistoryNet |date=25 February 2015 |access-date=2018-03-17}}</ref> More than 3,000 were produced and used as reconnaissance vehicles or [[light tank]]s.

It held the [[Guinness World Records|Guinness world record]] for the fastest production tank, recorded doing {{convert|82.23|km/h|abbr=on}} at the [[QinetiQ]] vehicle test track in [[Chertsey]], [[Surrey]], on 26 January 2002.<ref>{{cite web |url=http://www.guinnessworldrecords.com/world-records/fastest-tank/|title=Fastest tank |publisher=Guinnessworldrecords.com |date=2002-03-26 |access-date=2014-05-31}}</ref>

==History==
The CVR(T) family of vehicles came from a [[British Army]] requirement for an armoured fighting vehicle that could be rapidly airlifted to trouble spots. The Armoured Vehicle Reconnaissance was supposed to carry both a gun and an anti-tank missile but it was not possible to design an air portable vehicle to the specification. The limits on both size and weight led to the use of aluminium alloy for the hull and an adapted car engine for propulsion. The anti-tank capability was given to a dedicated vehicle, [[FV102 Striker|Striker]], while what became Scorpion would use a 76&nbsp;mm gun in the fire support role.

In 1967, Alvis was awarded the contract to produce 30 CVR(T) prototypes. Vehicles P1–P17, the Scorpion prototypes, were delivered on time and within the budget.{{sfnp|Foss|Sarson|1995|p=9}} After extensive hot and cold weather trials in [[Norway]], [[Australia]], [[Abu Dhabi]] and [[Canada]], the Scorpion was accepted by the British Army in May 1970, with a contract for 275, which later rose to 313 vehicles.{{sfnp|Foss|Sarson|1995|p=10}} The first production vehicles were completed in 1972 and the first British regiment to be equipped with the Scorpion were the [[Blues and Royals]] of the [[Household Cavalry]] in 1973.{{sfnp|Foss|Sarson|1995|p=10}}{{sfnp|Foss|Sarson|1995|p=4}} 
 
Alvis built more than 3,000 Scorpion vehicles for the British Army, [[Royal Air Force Regiment]] and the export market. All of the CVR(T) vehicles were to be air-portable; and two Scorpions could be carried in a [[Lockheed C-130 Hercules]]. Another requirement of the CVR(T) project was the low [[ground pressure]], similar to that of a soldier on foot; this would serve it well in the boggy conditions of the [[Falklands War]].

The Scorpion was armed with the low velocity 76&nbsp;mm L23A1 gun, which could fire [[high-explosive]], [[High explosive squash head|HESH]], smoke and [[Canister shot|canister]] rounds. Storage was provided for 40 or 42 rounds. A 7.62&nbsp;mm coaxial [[FN MAG|L7 GPMG]] (3,000 rounds carried) was also fitted, as were two multi-barrelled smoke grenade dischargers, one on each side of the turret.<ref name=janes /> The main armament has an elevation of 35 degrees and a depression of 10 degrees; the turret has a full 360-degree traverse.<ref>Foss & Sarson, p. 14</ref> The traverse was however hand-cranked, a cost-saving feature that made traversing the turret relatively slow and laborious relative to other vehicles of its type.<ref name=":0">{{Cite web|title=Tank Chats #109 Scorpion & TV15000 |date=30 October 2020 |publisher=The Tank Museum |url=https://www.youtube.com/watch?v=5qdaONEDRIo|access-date=2021-02-19|via=YouTube}}</ref> This gun was later deemed to be unsatisfactory, as RAF testing showed that the lack of a fume extraction system caused toxic fumes to enter the fighting compartment, endangering the crew's health.<ref name=":0" />

Some Scorpions used the Cockerill Mk3 90mm gun instead. This weapon could fire the following rounds:<ref>"AMMUNITION: Nexter Catalogue 2018." Pages 101-109. KNDS France. July 2018. Retrieved July 19, 2024.</ref>

===Engine===
The original engine was the [[Jaguar XK6 engine#4.2-litre|Jaguar J60 Mk 100b 4.2-litre]] petrol engine,<ref>{{cite book |url=https://books.google.com/books?id=k9cNAAAAQAAJ&pg=PA37 |first=Christopher |last=Chant |title=A Compendium of Armaments and Military Hardware |date=January 1987 |publisher=Routledge & Kegan Paul |isbn=9780710207203 |access-date=2014-05-31}}</ref> which was replaced by a [[Cummins UK|Cummins]] or [[Perkins Engines|Perkins]] diesel engine.<ref name=janes /> The maximum speed was about {{convert|50|mph|abbr=on}} and it could accelerate from standing to {{convert|30|mph|abbr=on}} in 16 seconds. The maximum speed on water (with the flotation screen deployed) was {{convert|3.6|mph|abbr=on}}.{{sfnp|Foss|Sarson|1995|p=12}} The Irish engineering company IED replaced the Jaguar engine in Irish Army Scorpions with a [[Steyr Motors GmbH|Steyr]] M16 TCA HD engine (6-cylinder, 145&nbsp;kW), making Irish Scorpions more powerful and more reliable in critical environments.<ref>[http://www.steyr-motors.com/automotive/applications-gallery/alvis-alvis-scorpion-cvr-t-m16-tca-hd-159/ Application Gallery] {{Webarchive|url=https://web.archive.org/web/20160420131304/http://www.steyr-motors.com/automotive/applications-gallery/alvis-alvis-scorpion-cvr-t-m16-tca-hd-159/ |date=20 April 2016 }}: Steyr-Motors.com</ref>{{Failed verification|date=May 2017}}

===Armour===
The FV101 was a very light armoured vehicle, weighing in at a mere 8 tonnes. This meant some compromises had to be made on protection. The vehicle had 12.7&nbsp;mm<ref name="books.google.com">[https://books.google.com/books?id=ddcRqnVDL9wC&pg=PA83 ''Thailand Army Weapon Systems Handbook''].</ref> of sloped aluminium armour on both the front and sides,<ref>{{cite web |title=Alvis FV107 Scimitar |url=https://www.militaryfactory.com/armor/detail.asp?armor_id=188 |website=militaryfactory.com |publisher=Military Factory}}</ref><ref>{{cite web |last1=Bocquelet |first1=David |title=FV101 Scorpion |url=http://www.tanks-encyclopedia.com/coldwar/UK/Alvis_Scorpion.php |website=tanks-encyclopedia.com |publisher=Tank Encyclopedia}}</ref> giving an average effective thickness of 25&nbsp;mm.<ref>{{cite web |title=FV 101 CVR(T) Scorpion |url=https://fas.org/man/dod-101/sys/land/row/scorpion.htm |website=fas.org |publisher=Federation of American Scientists}}</ref>

===Other systems===
The vehicle was fitted with a [[NBC (weapon)|nuclear, biological, chemical protection system]], [[image intensification]] sights for gunner and driver and a floatation screen.<ref name=janes /> A [[commode]]{{clarify|date=December 2022|reason=drawer or toilet?}} was located under the commander's seat. An internal water tank and a [[boiling vessel]] for cooking and heating water were also provided.{{sfnp|Foss|Sarson|1995|p=11}}

==Service history==
The Scorpion has been used by the armed forces of Belgium, Botswana, Brunei, Chile, Honduras, Iran, Indonesia, Ireland, Jordan, Malaysia, New Zealand, Nigeria, Oman, Philippines, Spain, Tanzania, Thailand, Togo, the [[United Arab Emirates]], and Venezuela.<ref name=janes /> The Iranian army acquired 250 Scorpions in the late 1970s and a number of them are still in use after being refurbished locally as the Tosan tank. Scorpions were on occasion deployed to main UK airports as a show of force against possible terrorist threats, e.g., [[Operation Marmion (1974)|Operation Marmion]] at [[Heathrow Airport]] in 1974.<ref>{{Cite book |title=The Military's Role in Counterterrorism: Examples and Implications for Liberal Democracies |last=Hughes |first=Geraint |publisher=[[Strategic Studies Institute]] |location=[[US Army War College]], Carlisle, PA |year=2011 |isbn=978-1584874898 |page=91 |url=http://www.dtic.mil/get-tr-doc/pdf?AD=ADA542502|archive-url=https://web.archive.org/web/20170312055916/http://www.dtic.mil/get-tr-doc/pdf?AD=ADA542502|url-status=dead|archive-date=12 March 2017}}</ref>{{Failed verification|date=March 2017}} Similar operations in 2003 used the then-current [[FV107 Scimitar|Scimitar]].

===Combat use===
[[File:FV101 Scorpion Iraq 1991.jpg|thumb|alt=small armoured vehicle alone in the desert. The flag of the United Kingdom can just be seen on the rear|Scorpion advancing across the desert during the first [[Gulf War]].]]

B Squadron, [[Blues and Royals]] were airlifted and deployed into the [[Akrotiri and Dhekelia]] Sovereign Base areas, during the [[Turkish invasion of Cyprus]] 1974.

Two troops from B Squadron, Blues and Royals served in the [[Falklands War]]. One troop was equipped with four Scorpions, the other with four [[FV107 Scimitar]]s. These were the only armoured vehicles used in action by the British Army during the conflict.{{Sfnp|Foss|Sarson|1995|p=21}} Two Scorpions and two Scimitar supported a diversionary attack by [[Scots Guards]] on [[Argentine Marines]]' entrenchments in the southern slopes of [[Battle of Mount Tumbledown|Mount Tumbledown]] in the early hours of 13 June 1982. One Scorpion manoeuvred off the track and was disabled by an anti-tank mine.<ref>{{Cite book |last=Clack |first=Timothy |title=1982 Uncovered: The Falklands War Mapping Project |last2=Pollard |first2=Tony |publisher=Archaeopress Publishing Limited |year=2022 |isbn=9781803273839 |pages=19 |language=en}}</ref>

Scorpions also served in the [[Gulf War]]. The 16th/5th The Queen's Royal Lancers deployed in the first Gulf War (Operation Granby) using all variants of the CVR(T) range carrying out the role of force reconnaissance for the British spearhead towards Iraq, operating forward of other official green army units. The [[1st The Queen's Dragoon Guards]], a reconnaissance regiment, had 32 and the close reconnaissance troops of the armoured regiments each had eight.{{Sfnp|Foss|Sarson|1995|pp=41–44}} They were also used by [[No. 1 Squadron RAF Regiment]], which was attached to the British [[1st (United Kingdom) Division|1st Armoured Division]].

===Foreign users===
The [[Botswana Defence Force]], the [[Islamic Republic of Iran Army Ground Forces|Iranian Army]] and the [[Nigerian Army]] continue to use Scorpions, in some cases up-armed with the 90&nbsp;mm Cockerill.

The Iranian army used its Scorpion tanks in the [[Iran–Iraq War]], with various degrees of success. Early in the war, Iran used the Scorpions's "accurate fire" (alongside the Cobra attack helicopters) to hold back the Iraqi [[2nd Infantry Division (Iraq)|2nd Infantry Division]]'s offensive towards the city of Ilam.{{sfnp|Razoux|2015}}
However, the Scorpions proved less effective when faced with Iraq's [[9th Armoured Division (Iraq)|9th Armoured Division]]:{{sfnp|Razoux|2015}}

<blockquote>A second [Iraqi] column rushed to Susangerd, which it crossed without encountering any resistance, the city having apparently been left defenseless. The column continued in the direction of Hamidiyeh. It came into contact with the [Iranian] [[92nd Armored Division (Iran)|92nd Armored Division]]'s reconnaissance regiment, which met it with effective in-depth defense. Yet the Iranians eventually had to yield in the face of Iraqi pressure. Their Scorpions' 90&nbsp;mm guns did not hold their weight against the T-62 tanks' 115&nbsp;mm guns. The Iraqis thus took control of Hamidiyeh, then Bozorg.</blockquote>

The British government provided Iran (and Iraq) with limited parts for their Scorpions during the war:{{sfnp|Razoux|2015}}

<blockquote>Regarding military matters, the British government imposed two strict rules: contracts signed before the war would be honored, but the sale of equipment likely to significantly increase either side's military capacities was banned. Interpreting these regulations loosely, the British government delivered both the Iranians and the Iraqis motors and spare parts for Chieftain and Scorpion tanks, which would allow the former to maintain tanks acquired under the Shah and the latter to repair tanks captured from the Iranian army.</blockquote>

'''Turret only'''
* '''[[M113 armoured personnel carriers in Australian service#Fire support vehicles|M113A1 MRV]]'''

During the late 1960s, as a result of its experiences in the [[Vietnam War]], the [[Australian Army]] perceived a need for a hybrid, tracked fire support and reconnaissance vehicle.

Experiments in which existing [[M113]] APCs were fitted with [[Alvis Saladin|Saladin]] (not Scorpion) turrets, wielding a 76&nbsp;mm M1 gun, were successful. The vehicle entered service as the M113A1 FSV (Fire Support Vehicle).

A very similar, subsequent vehicle, attaching the turret from the Scorpion to the M113, was also known as the FSV. (This re-purposing of the turret was to be the only use of any part of the Scorpion by the [[Australian Defence Force|ADF]].) Entering service in 1976, it was later redesignated the '''M113A1 Medium Reconnaissance Vehicle''' (MRV). Its development also obviated interest in acquiring brand new, purpose-built vehicles (such as a variant of the UK [[Combat Vehicle Reconnaissance (Tracked)|CVR(T)]] or the [[Bradley fighting vehicle|M2/M3 Bradley]]).  All of these vehicles were retired in 1996.<ref>{{cite web |url=http://www.army.gov.au/Our-work/News-and-media/50-years-service-for-M113 |title=50 years service for M113 - Australian Army |access-date=2016-02-20 |url-status=dead |archive-url=https://web.archive.org/web/20160502182343/http://army.gov.au/Our-work/News-and-media/50-years-service-for-M113 |archive-date=2 May 2016 |df=dmy-all }}</ref>
