== History ==

=== Saturn I and IB (1964–1968) ===
Launch Complex 37 began construction in 1959, being envisioned to be a second site to launch the experimental [[Heavy-lift launch vehicle|heavy-lift]] [[Saturn (rocket family)|Saturn]] rockets, joining [[Cape Canaveral Launch Complex 34|Launch Complex 34]] (LC-34) to the south. Originally, it was planned to be the launch site for an [[Earth orbit rendezvous]] (EOR) strategy to potentially be taken by the Apollo program, where a launch vehicle such as the [[Saturn C-3]] would launch both the [[trans-lunar injection]] stage and the [[Apollo Lunar Module|Lunar Excursion Module]] from the two pads, while the crew would lift off from LC-34 and intercept the two payloads in [[low Earth orbit]]. Despite [[NASA]] opting for a [[Lunar orbit rendezvous]] (LOR) approach and using the [[Saturn V]] from [[Kennedy Space Center Launch Complex 39|Launch Complex 39]] to the north, they nonetheless accepted LC-37 to support the [[Saturn I|Saturn&nbsp;I]] program in 1963.<ref name="FAS">{{cite web |url=https://fas.org/spp/military/facility/ccas-lc-37.htm |title=Complex 37 -- Cape Canaveral Air Station |access-date=2008-05-28 |publisher=Federation of American Scientists (www.fas.org) |date=2000-06-16 |archive-date=2008-04-20 |archive-url=https://web.archive.org/web/20080420093207/http://www.fas.org/spp/military/facility/ccas-lc-37.htm |url-status=dead}}</ref> [[File:Apollo 5 on pad.jpg|thumb|[[Apollo 5]] at LC-37B in 1968|left]]
The original layout of the launch complex featured one Mobile Service Structure which could be used to service or mate a rocket on either LC-37A or 37B, but not on both simultaneously. The first launch from LC-37 came on January 29, 1964, launching [[Saturn I SA-5]] as part of the rocketry development portion of the Apollo program. Over the next two years, a total of six uncrewed Saturn&nbsp;I flights were launched from the complex, mostly carrying [[Boilerplate (spaceflight)|boilerplate]] [[Apollo command and service module|Apollo capsules]] alongside the three launches of the [[Pegasus (satellite)|Pegasus]] project.

In late 1965, both LC-37 and LC-34 were modified to launch the Saturn I's successor, the [[Saturn IB]]. Similarly to its previous configuration, this was in support of Apollo development before the Saturn V's activation at [[Kennedy Space Center]]; however, the original purpose of EOR was also made ready as a backup in case complications render the Saturn V and LOR unfeasible. Only two Saturn IB launches were made from LC-37: the first one was [[AS-203]] (or informally Apollo 3), which launched on July 5, 1966 and tested engine restart capabilities on the [[S-IVB]] upper stage. The second one was [[Apollo 5]], lifting off on January 22, 1968 and carrying the first operational test of the [[Apollo Lunar Module]] in space.<ref name="FAS" /> The facility was deactivated in 1972, following the conclusion of the Apollo program. Proposals were drawn of resuming Saturn IB launches from LC-37 and LC-34 as part of the [[Apollo Applications Program]], but NASA instead opted to modify [[Kennedy Space Center Launch Complex 39B|Launch Complex 39B]] for that role. LC-37 would sit dormant for the next 30 years.

=== Delta IV and Delta IV Heavy (2002–2024) ===
In 1998, the [[United States Air Force]] and [[Boeing]] came into an agreement to use LC-37 for launching the [[Delta IV]] as part of the [[National Security Space Launch|Evolved Expendable Launch Vehicle]] program, getting rechristened as SLC-37 as a result of doing so. Having acquired the [[Delta (rocket family)|Delta family]] following their merger with [[McDonnell Douglas]] the previous year, Boeing aimed for the Delta IV to be a complement and not a replacement to the other active members of the time, the [[Delta II]] and [[Delta III]]. As such (and taking the difference in lift capabilities into account), a new launch site similar in size to SLC-37 was needed rather than continuing to use [[Cape Canaveral Space Launch Complex 17|Space Launch Complex 17]] (SLC-17). Facility modifications were made to SLC-37B in 2001, constructing a {{convert|330|ft|abbr=on}} tall Mobile Service Tower fitted to service all planned Delta IV configurations.<ref>{{cite web |date=March 2, 2000 |title=Boeing, Raytheon Top Off Nation's Newest Launch Tower |url=http://www.boeing.com/news/releases/2000/news_release_000302h.html |url-status=dead |archive-url=https://web.archive.org/web/20081202004817/http://www.boeing.com/news/releases/2000/news_release_000302h.html |archive-date=2008-12-02 |publisher=Boeing}}</ref> The complex was officially put into active service with the first launch of the Delta IV on November 20, 2002, carrying [[Eutelsat 33B|Eutelsat 70A]] to [[geostationary transfer orbit]].

On December 21, 2004, SLC-37 supported the maiden flight of the [[Delta IV Heavy]], which aimed at carrying a boilerplate and an assortment of small satellites into orbit. The next year, citing issues that sprang up with competition, Boeing announced that Delta operations at the pad and at SLC-17 would be combined with those of [[Atlas V]] at [[Cape Canaveral Space Launch Complex 41|Space Launch Complex 41]] (SLC-41) as part of a [[joint venture]] with [[Lockheed Martin]]. This handover would be made official with the establishment of [[United Launch Alliance]] (ULA) in December 2006, and SLC-37 supported its first launch under ULA with a Delta IV Heavy flight on November 11, 2007. 

During the Delta IV era, SLC-37 underwent 35 launches of the family, consisting of 29 Medium launches and 16 Heavy launches.<ref>{{cite web |title=Launch Complex 37 |url=https://ccspacemuseum.org/facilities/launch-complex-37/ |access-date=September 30, 2023 |publisher=Cape Canaveral Space Force Museum}}</ref> Almost all payloads launched were governmental in nature, with a majority of that subsection being military customers such as the Air Force, the [[United States Navy]], and the [[National Reconnaissance Office]]. Some notable missions launched from the facility include [[GOES 13|GOES-N]], [[GOES 14|GOES-O]], and [[GOES 15|GOES-P]] for [[National Oceanic and Atmospheric Administration|NOAA]] throughout the late 2000s, [[Exploration Flight Test-1]] for NASA's [[Orion (spacecraft)|Orion]] spacecraft in 2014, and the [[Parker Solar Probe]] in 2018.

Throughout the late 2010s and early 2020s, ULA began to wind down operations at the complex in preparation for the Delta IV's retirement. Their new launch vehicle to replace the Delta and Atlas families, [[Vulcan Centaur]], was planning on having its launch site be at SLC-41 and as such ULA opted to let the SLC-37 lease expire. The final Delta IV Medium launch came on August 22, 2019 carrying a [[Global Positioning System|GPS]] satellite for the Air Force, while the last overall launch of the Delta family came with a Delta IV Heavy launch for the NRO on April 9, 2024.<ref>{{cite web |date=22 August 2019 |title=Delta IV Medium's well-earned retirement with GPS finale |url=https://www.nasaspaceflight.com/2019/08/delta-iv-medium-retirement-gps-finale/ |access-date=September 30, 2023 |publisher=NASASpaceflight}}</ref>

=== Proposals for Starship (from 2025) ===
During the lead up to the Delta IV's retirement, the [[United States Space Force]] (having taken over the Air Force's jurisdiction at Cape Canaveral) and [[SpaceX]] started to survey using SLC-37 as a launch site for [[SpaceX Starship|Starship]], complementing their launch site at [[SpaceX Starbase|Starbase]] and existing plans at KSC's [[Kennedy Space Center Launch Complex 39A|Launch Complex 39A]], with the [[Federal Aviation Administration]] being tasked with creating an [[environmental impact statement]] (EIS) as part of procedure.<ref>{{Cite web |last=Foust |first=Jeff |date=2024-02-17 |title=Space Force to study Cape Canaveral launch sites for Starship |url=http://spacenews.com/space-force-to-study-cape-canaveral-launch-sites-for-starship/ |access-date=2025-06-12 |website=SpaceNews |language=en-US}}</ref> In March 2025, SpaceX announced that they received a limited [[right of entry]] for SLC-37, with the draft EIS being released in June following a delay from December 2024.<ref>{{Cite web |last=SpaceX |author-link=SpaceX |date=3 March 2025 |title=Future of Building Starship |url=https://www.spacex.com/updates/ |website=spacex.com}}</ref><ref>{{Cite web |last=Stone |first=Mark |date=2024-03-17 |title=Starship Coming to Florida |url=https://www.hernandosun.com/2024/03/17/starship-coming-to-florida/ |access-date=2024-04-14 |website=Hernando Sun |language=en-US}}</ref>

In the report, plans call for the construction of two launch pads with integration towers located on the eastern site of SLC-37, being able to support a potential flight cadence of 76 launches per year.<ref name=":0" /> In addition, any preexisting infrastructure from the complex's previous incarnations would get removed, with two catch towers analogous to the [[Landing Zones 1 and 2|Falcon 9 landing zones]] being built in place.<ref>{{Cite tweet |number=1931039805548204500 |user=SpaceflightNow |title=The @usairforce published its Draft Environmental Impact Statement on SpaceX's proposal to use pad 37 at Cape Canaveral Space Force Station to launch Starship-Super Heavy up to 76 times annually.

At the current moment, SpaceX does not hold a lease for SLC-37, with any actions made to the pad being done with their right of entry. However, an official announcement is expected to occur following the final study's release in September 2025.<ref name="Ars Tech June 2025" />
