The Taifun-1Yu, a modification of the basic design with smooth calibration surfaces, was to be in service by 1980. Instead trials were conducted from 1979-1981 and the design was not accepted for military service until 7 February 1983. The basic satellite was spherical in shape and 2.0 m in diameter.

Length: 2.00 m (6.50 ft). Maximum Diameter: 2.00 m (6.50 ft). Span: 2.00 m (6.50 ft). Associated Launch Vehicle: Kosmos 11K65M.
