STS-53 (Discovery)
1992-086A
The STS-53 flight was the final classified DoD mission. It is thought to have carried an SDS communications satellite which relays spy satellite imagery for the NRO.
An attempt to deploy the ODERACS calibration spheres failed. On day 6, the GLO experiment studied orbiter glow. 8 cycles of the CRYOHP heat pipe experiment were carried out, exceeding planned gaols.

Salyut 2A
1972-F04
The second DOS station, DOS 2 or 17K No. 122, was launched on 1972 Jul 30. However, the Proton-K second stage shut down early at 90 km altitude and the new space station fell into the Pacific Ocean. It would have been named Salyut-2 if successful.
