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 an accident that killed all seven crewmembers aboard. Initially manufactured as a test article not intended for spaceflight, it was utilized for ground testing of the Space Shuttle orbiter's structural design. However, after NASA found that their original plan to upgrade Enterprise for spaceflight would be more expensive than upgrading Challenger, the orbiter was pressed into operational service in the Space Shuttle program. Lessons learned from the first orbital flights of Columbia led to Challenger's design possessing fewer thermal protection system tiles and a lighter fuselage and wings. This led to it being 1,000 kilograms lighter than Columbia, though still 2,600 kilograms heavier than Discovery.
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. 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.
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 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 Second Artillery Corps (SAC) which, in 2009, was estimated to have under 15 DF-31 missiles and under 15 DF-31A missiles in inventory. 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 February 1962, Friendship 7 flight aboard which John Glenn became the first American to orbit the Earth.
Launch Complex 26 (LC-26) is a deactivated launch site at Cape Canaveral Space Force Station, Florida. LC-26 consisted of two pads, A and B. Pad A was used for the Jupiter-C and Juno I rockets, and was the launch site for Explorer 1, the United States' first satellite, in 1958. Pad B was used for Juno II. Jupiter IRBMs were launched from both pads.
The Cape Canaveral Space Force Museum is located at Launch Complex 26 at Cape Canaveral Space Force Station, Florida.

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 13 (LC-13) was a launch complex at Cape Canaveral Space Force Station, 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.
Launch Complex 16 (LC-16) at Cape Canaveral Space Force Station, Florida is a launch complex built for use by LGM-25 Titan missiles, and later used for NASA operations before being transferred back to the US military and used for tests of MGM-31 Pershing missiles. Six Titan I missiles were launched from the complex between December 1959 and May 1960. These were followed by seven Titan II missiles, starting with the type's maiden flight on March 16, 1962. The last Titan II launch from LC-16 was conducted on May 29, 1963.
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).
