Space Launch Complex 1 (SLC-1) is an inactive launch complex at Vandenberg Space Force Base in California. It consists of two pads, SLC-1E (formerly Pad 75-3-5) and SLC-1W (formerly Pad 75-3-4). Both sites were built in 1958 for the never activated 75th Strategic Missile Squadron for launches of the Thor-Agena to support the CORONA series of reconnaissance satellites for the CIA. Under the masquerade of the Discoverer program, SLC-1 served as the launch site of numerous firsts for spaceflight, such as the first satellite in polar orbit with Discoverer 2, the first recovery of an object from orbit with Discoverer 13, and the first recovery of film from orbit with Discoverer 14. SLC-1 continued to launch various spy satellites such as the KH-4 for the Department of Defense throughout the 1960s, following the transfer of vehicle operations from the CIA to the National Reconnaissance Office. During the mid-60s, as part of the phasing out of the Thor-Agena, both pads were modified to launch the succeeding Thorad-Agena throughout the end of the decade. Ultimately, thanks to the KH-4 getting replaced by the larger KH-9 and KH-11 as well as the pads' proximity to the more actively used Space Launch Complex 2, SLC-1 eventually saw the end of active service by the 1970s, and have since been disused.
Space Launch Complex 3 (SLC-3) is a launch site at Vandenberg Space Force Base that consists of two separate launch pads. SLC-3E (East) was used by the Atlas V launch vehicle before it was decommissioned in August 2021 with the final launch taking place on November 10, 2022 at 09:49, while SLC-3W (West) has been demolished.
Thorad-Agena was an American expendable launch system, derived from the Thor and Delta rockets.
Space Launch Complex 2 (SLC-2) is an active rocket launch site at Vandenberg Space Force Base, in California, USA. It consists of two launch pads: SLC-2E, used by the PGM-17 Thor and several of its derivatives from 1958 to 1972, and SLC-2W, which is currently used by the Firefly Alpha after historically being the west coast launch site of the Delta II.
Space Launch Complex 4 (SLC-4) is a launch and landing site at Vandenberg Space Force Base, California, U.S. It has two pads, both of which are used by SpaceX for Falcon 9, one for launch operations, and the other as Landing Zone 4 (LZ-4) for SpaceX landings.
Discoverer 24, also known as Corona 9018A, was an American area survey optical reconnaissance satellite which was launched in 1961 but failed to achieve orbit. It was a KH-5 Argon satellite, based on an Agena-B. It was the third KH-5 to be launched.
Discoverer 27, also known as Corona 9020A, was an American area survey optical reconnaissance satellite launched in 1961, but which failed to achieve orbit. It was a KH-5 Argon satellite, based on an Agena-B. It was the fourth KH-5 to be launched, the second consecutive KH-5 launch failure, and the fourth consecutive KH-5 mission failure.
FTV-1126, also known as Corona 9034A, was an American area survey optical reconnaissance satellite launched in 1962. It was a KH-5 Argon satellite, based on an Agena-B. It was also unofficially known as Discoverer 41, a continuation of the designation sequence used for previous US reconnaissance satellites, which had officially been discontinued after Discoverer 38. It was the first KH-5 satellite to complete its mission successfully.
Discoverer 22, also known as Corona 9015, was an American optical reconnaissance satellite which was lost in a launch failure in 1961. It was the fourth of ten Corona KH-2 satellites, based on the Agena-B.
Discoverer 26, also known as Corona 9019, was an American optical reconnaissance satellite which was launched in 1961. It was the sixth of ten Corona KH-2 satellites, based on the Agena-B.
Discoverer 28, also known as Corona 9021, was an American optical reconnaissance satellite which was lost in a launch failure in 1961. It was the seventh of ten Corona KH-2 satellites, based on the Agena-B.
Discoverer 16, also known as Corona 9011, was an American optical reconnaissance satellite which was lost in a launch failure on 26 October 1960. It was the first of ten Corona KH-2 satellites, based on the Agena-B.
Discoverer 17, also known as Corona 9012, was an American optical reconnaissance satellite launched on 12 November 1960 at 20:38:00 GMT. It was the second of ten Corona KH-2 satellites, based on the Agena-B.
Discoverer 29, also known as Corona 9023, was an American optical reconnaissance satellite which was launched in 1961. It was the first KH-3 Corona''' satellite, which was based on an Agena-B rocket.
Discoverer 31, also known as Corona 9024, was an American optical reconnaissance satellite which was launched in 1961. It was a KH-3 Corona''' satellite, based on an Agena-B.
Discoverer 32, also known as Corona 9025, was an American optical reconnaissance satellite which was launched in 1961. It was a KH-3 Corona''' satellite, based on an Agena-B.
Discoverer 33, also known as Corona 9026, was an American optical reconnaissance satellite which was lost in a launch failure in 1961. It was the eighth of ten Corona KH-2 satellites, based on the Agena-B.
DISCOVERE 34, also known as CORONA 9027, was a United States optical reconnaissance satellite which was launched on 5 November 1961. It was the ninth of ten CORONA KH-2 satellites, based on the Agena B.
Discoverer 35, also known as Corona 9028, was an American optical reconnaissance satellite which was launched in 1961. It was the last of ten Corona KH-2 satellites, based on the Agena-B.
Discoverer 36, also known as Corona 9029, was an American optical reconnaissance satellite which was launched in 1961. It was a KH-3 Corona satellite, based on an Agena-B rocket. It was the penultimate KH-3 satellite to be launched, the last successful mission, and the most successful of the program.
Discoverer 37, also known as Corona 9030, was an American optical reconnaissance satellite which was lost in a launch failure in 1962. It was the last KH-3 Corona satellite, which was based on an Agena-B rocket.
