Atlas H
Expendable launch vehicle
The Atlas H was an American expendable launch system derived from the SM-65 Atlas missile.[1] It was a member of the Atlas family of rockets, and was used to launch five clusters of NOSS satellites for the US National Reconnaissance Office.[1] Two flights also carried LiPS satellites, as secondary payloads for the United States Naval Research Laboratory.[1]

The Atlas H was a stage and a half rocket, using the enhanced Atlas rocket designed for use as the first stage of the Atlas G rocket,[2] which differed from the Atlas H in having a Centaur upper stage. This stage was later reused as the first stage of the Atlas I. In practice, an MSD upper stage was flown on all five launches.[3]
Atlas H could put a payload of 3,630 kg (8,000 lb) into low Earth orbit, or a payload of 2,255 kg (4,971 lb) into a geostationary transfer orbit.[1]
