The baseline Atlas II increased Atlas-Centaur performance for Defense Satellite Communications System, UHF Follow-On, and commercial payloads. Its pressure-stabilized Atlas stage used the MA-5A propulsion system and fed a two-engine Centaur II. Ten vehicles flew successfully from Eutelsat II F3 in December 1991 through UHF F8 in March 1998.
