OV1 [USAF]

The OV1 (Orbiting Vehicle 1) were small research satellite to be launched piggy back on Atlas ICBM test flights. They consisted in general of the OV1 satellite and the OV1-PM propulsion module to reach orbit. Only OV1 1 and OV1 3 were launched on a ICBM, while all other Atlas flights were dedicated launches. OV1 6 did not have a propulsion module as it was launched on the MOL testflight on a Titan-3C. OV1 8, OV1 16, OV1 20 and OV21 featured other payloads substituting the OV1 satellite. OV1 86 consisted of the spare OV1 8 satellite body and the OV1 6 propulsion module. In some cases, the PM did also carry an research payload (OV1 17A, OV1 20, OV1 21).
