The FLTSATCOM system provided world-wide, high-priority UHF communications between naval aircraft, ships, submarines, and ground stations and between the Strategic Air Command and the national command authority network.

Planned first test manned flight of the TKS large ferry craft. Would have docked with the Almaz OPS 4 military space station. Flight cancelled with the rest of the Almaz program in 1981. The spacecraft was instead flown unmanned to Salyut 6 as Cosmos 1267.

NPO Energia developed for the Ministry of Defence the interorbital tug Gerkules with 550 kW maximum output and continuous operation in the 50-150 kW range for 3 to 5 years. In 1986 an interorbital tug was studied to solve the specific application of transporting heavy satellites of 100 tonnes to geostationary orbit, launched by Energia.

Oceanographic, terrestrial studies. Development of methods for comprehensive study of the oceans and the surface of the earth, and testing of the experimental system of automatic gathering of scientific information from sea and land stations. Launched under the INTERCOSMOS programme by the USSR together with the Czechoslovak Socialist Republic, the German Democratic Republic, the Hungarian People's Republic and the Socialist Republic of Romania.

Production of the four 37KS modules was approved following review of the draft projects. The four modules would be placed into orbit by a Proton launch vehicle. An FGO tug section, connected to the 37KS module by a light lattice structure, would rendezvous with the Mir station and dock the module to one of the radial ports of the Mir station. It would then separate and deorbit itself into the earth's atmosphere. The plan was that production of all of the modules would be completed in 1984. They would be assembled with the Mir base block in one year and have an operational lifetime of five years.
