The OV2 (Orbiting Vehicle 2) series satellites were originally built for project ARENTS (Advanced Research Environmental Test Satellite), which was intended to obtain supporting data for the Vela program. After the cancellation of the ARENTS program, the already built hardware was reused for OV2, a low-cost series of experimental satellites, which were to be launched for free on Titan-3C test flights to very different orbits.

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.

The United States Air Force (USAF) is the air service branch of the United States Armed Forces, and is one of the eight uniformed services of the United States. Originally created on 1 August 1907, as a part of the United States Army Signal Corps, the USAF was established as a separate branch of the United States Armed Forces in 1947 with the enactment of the National Security Act of 1947.
