This was a modernized Molniya-1 communications satellite with the 'Beta' retransmitter which began flight tests in 1970. The system was operational by 1972. Communications stations for the Rocket Forces, Air Force, and Navy were in place by 1975 (Ruchey Command and Control System). The satellite itself was part of the Korund system, which allowed strategic communications and telephony with military units in Siberia and the Far East.

The complete system included 8 spacecraft, in four orbital planes, replenished as necessary. The satellite reliability improved over time, with a maximum life of about four years. The system used Surgut secure radio lines and had a 20 year system life, with 70 launches total. The improved Korund-M system began flight trials in 1983 and was accepted into military service in 1987.

Although the system supported the Russian Orbita Television network, the principal function was to service government and military communications traffic via a single 40 W, 1.0/ 0.8 GHz transponder. From Molniya 1-75 in 1989, all Molniya-1T spacecraft were launched from the Plesetsk Cosmodrome by the Molniya booster.

The average launch rate in the 1970's and 1980's was over three per year. After 1993 this declined to one launch every other year. However the much-reduced network evidently could still support essential military communications within Russian territory.

Typical orbit: 900 km x 39000 km at 64 degrees inclination. Length: 4.40 m (14.40 ft). Maximum Diameter: 1.40 m (4.50 ft). Span: 8.20 m (26.90 ft). Mass: 1,656 kg (3,650 lb).
