Vela 4A & 4B - Space launch mission detailed information
Vela 4A & 4B
28 APR 1967
United States Air Force
Space Launch Complex 41
Like its predecessor, the Vela, the Advanced Vela series of spacecraft were designed to monitor worldwide compliance with the 1963 nuclear test ban treaty.
The Titan IIIC was an expendable launch system used by the United States Air Force from 1965 until 1982. It was the first Titan booster to feature large solid rocket motors and was planned to be used as a launcher for the Dyna-Soar, though the spaceplane was cancelled before it could fly. The majority of the launcher's payloads were DoD satellites, for military communications and early warning, though one flight (ATS-6) was performed by NASA. The Titan IIIC was launched exclusively from Cape Canaveral while its sibling, the Titan IIID, was launched only from Vandenberg AFB.
