    ASAT interceptor. Intercepted Cosmos 248 target on second orbit. Repeatedly approached Cosmos 248, verifying primary and reserve homing and guidance systems. Destroyed itself in test of on-board destruct system. Counted as a failure by Western observers because that target was not destroyed; but this was not an objective of the test. Left 109 fragments in orbit, of which 54 were still in orbit in 1996.

    Passive naval electronic intelligence satellite. The satellite was placed in an initial 147 km x 442 km orbit at 65 degree inclination. The US-PM's propulsion module fired at apogee to circularize the orbit. Replaced the only previous remaining US-PM satellite which ended operations in November and reentered earlier in December 1999.
