It was built in 1959 with LC-32 for the U.S. Air Force to conduct test launches of the first LGM-30 Minuteman missiles. LC-31 was built next to Navaho complex LC-9, requiring LC-10 to be demolished. These complexes were the first to feature dual launch pads, one of which was subterranean. LC-31 consisted of a blockhouse, static launch pad (31A) and missile silo (31B). The beehive-shaped blockhouse is 210 yards from the static pad and 330 yards from the silo.
Between February 1, 1960 and September 23, 1969 the Air Force launched a total of four Minuteman missiles from pad 31A and 35 from silo 31B. Pad 31A was used later by the U.S. Army to test launch twelve Pershing 1a missiles.
Remains of Challenger lowered into silo at LC-31
The service tower has since been removed; the silo remains, and contains recovered debris from the Space Shuttle orbiter vehicle Challenger.[1][2]
2015 opening of the silo
In 2015, NASA opened the silo and removed several pieces of Challenger's debris, so they could be placed on permanent display at the Kennedy Space Center Visitor Complex.[3]
Space Shuttle Challenger (OV-099) was a Space Shuttle orbiter manufactured by Rockwell International and operated by NASA. Named after the commanding ship of a nineteenth-century scientific expedition that traveled the world, Challenger was the second Space Shuttle orbiter to fly into space after Columbia, and launched on its maiden flight in April 1983. It was destroyed in January 1986 soon after launch in a disaster that killed all seven crewmembers aboard.
The LGM-30 Minuteman is an American land-based intercontinental ballistic missile (ICBM) in service with the Air Force Global Strike Command. As of 2024, the LGM-30G is the only land-based ICBM in service in the United States and represents the land leg of the U.S. nuclear triad, along with the Trident II submarine-launched ballistic missile (SLBM) and nuclear weapons carried by long-range strategic bombers.
Vandenberg Space Force Base, previously Vandenberg Air Force Base, is a United States Space Force Base in Santa Barbara County, California. Established in 1941, Vandenberg Space Force Base is a space launch base, launching spacecraft from the Western Range, and also performs missile testing. The United States Space Force's Space Launch Delta 30 serves as the host delta for the base, equivalent to an Air Force air base wing. In addition to its military space launch mission, Vandenberg Space Force Base also hosts space launches for civil and commercial space entities, such as NASA and SpaceX.
The Martin Marietta SM-68A/HGM-25A Titan I was the United States' first multistage intercontinental ballistic missile (ICBM), in use from 1959 until 1962. Though the SM-68A was operational for only three years, it spawned numerous follow-on models that were a part of the U.S. arsenal and space launch capability. The Titan I was unique among the Titan models in that it used liquid oxygen and RP-1 as propellants; all subsequent versions used storable propellants instead.
Cape Canaveral Space Force Station (CCSFS) is an installation of the United States Space Force's Space Launch Delta 45, located on Cape Canaveral in Brevard County, Florida.
The PGM-19 Jupiter was the first nuclear armed, medium-range ballistic missile (MRBM) of the United States Air Force (USAF). It was a liquid-propellant rocket using RP-1 fuel and LOX oxidizer, with a single Rocketdyne LR79-NA rocket engine producing 667 kilonewtons (150,000 lbf) of thrust. It was armed with the 1.44 megatons of TNT (6.0 PJ) W49 nuclear warhead. The prime contractor was the Chrysler Corporation.
Launch Complex 39 (LC-39) is a rocket launch site at the John F. Kennedy Space Center on Merritt Island in Florida, United States. The site and its collection of facilities were originally built as the Apollo program's "Moonport" and later modified for the Space Shuttle program.
The Minuteman Missile National Historic Site is an American national historic site established in 1999 near Wall, South Dakota, to illustrate the history and significance of the Cold War, the nuclear arms race, and intercontinental ballistic missile (ICBM) development. The site preserves the last intact Minuteman II ICBM system in the United States, in a disarmed and demilitarized status. Guided tours are available of the underground Launch Control Center, and a missile silo can be observed from above. Some 450 of the newer Minuteman III missiles are still on active duty at Malmstrom AFB, Montana, Minot AFB, North Dakota, and F. E. Warren AFB, Wyoming.
The Dong Feng 31 is a third-generation long-range, road-mobile, three stage, solid-fuel rocket intercontinental ballistic missile (ICBM) in the Dongfeng missile series developed by the People's Republic of China. It is designed to carry a single 1-megaton thermonuclear weapon. It is a land-based variant of the submarine-launched JL-2. It is operated by the People's Liberation Army Rocket Force (PLARF). In 2009, the Chinese inventory was estimated as under 15 DF-31 missiles and under 15 DF-31A missiles. US Air Force National Air and Space Intelligence Center estimates that as of June 2017, five to ten Mod 1 and over fifteen Mod 2 launchers were operationally deployed.
Space Launch Complex 17 (SLC-17), previously designated Launch Complex 17 (LC-17), was a launch site at Cape Canaveral Air Force Station (CCAFS), Florida used for Thor and Delta launch vehicles launches between 1958 and 2011.
Launch Complex 14 (LC-14) is a launch site at Cape Canaveral Space Force Station in Florida. LC-14 was used for various crewed and uncrewed Atlas launches, including the Friendship 7 flight aboard which John Glenn became the first American to orbit the Earth in February 1962.

It is on the south end of Cape Canaveral, close to Launch Complex 5, with which it shared a blockhouse. With LC-5, it was the location of the first tests of the mobile launch concept designed by Kurt H. Debus. This concept was revised and improved and eventually used at LC-39 for the Saturn V and Space Shuttle.
Launch Complex 11 (LC-11) at Cape Canaveral Space Force Station, Florida, is a launch complex used by Atlas missiles between 1958 and 1964. It is the southernmost of the launch pads known as Missile Row. When it was built, it, along with complexes 12, 13 and 14, featured a more robust design than many contemporary pads, due to the greater power of the Atlas compared to other rockets of the time. It was larger, and featured a concrete launch pedestal that was 6 metres (20 ft) tall and a reinforced blockhouse. The rockets were delivered to the launch pad by a ramp on the southwest side of the launch pedestal.
Launch Complex 12 (LC-12) at Cape Canaveral Space Force Station, Florida was a launch pad used by Atlas rockets and missiles between 1958 and 1967. It was the second-most southern of the pads known as Missile Row, between LC-11 to the south and LC-13 to the north. Along with Complexes 11, 13 and 14, LC-12 featured a more robust design than many contemporary pads, due to the greater power of the Atlas compared to other rockets of the time. It was larger, and featured a concrete launch pedestal that was 6 metres (20 ft) tall and a reinforced blockhouse. The rockets were delivered to the launch pad by means of a ramp on the southwest side of the launch pedestal.
Launch Complex 13 (LC-13) was a launch complex at Cape Canaveral Space Force Station (CCAS), the third-most southerly of the original launch complexes known as Missile Row, lying between LC-12 and LC-14. In 2015, the LC-13 site was leased by SpaceX and was renovated for use as Landing Zone 1 and Landing Zone 2, the company's East Coast landing location for returning Falcon 9 and Falcon Heavy launch vehicle booster stages. It is leased by US Space Force to Phantom Space and Vaya Space who will operate this launch complex after the termination of SpaceX's lease in future.
A missile launch facility, also known as an underground missile silo, launch facility (LF), or nuclear silo, is a vertical cylindrical structure constructed underground, for the storage and launching of intercontinental ballistic missiles (ICBMs), intermediate-range ballistic missiles (IRBMs), medium-range ballistic missiles (MRBMs). Similar facilities can be used for anti-ballistic missiles (ABMs).
