Cosmos 185



Cosmos 185 was the first test of the Istrebitel Sputnik satellite. It was the first launch of the Tsyklon 2 launch vehicle.

The Istrebitel Sputnik was approximately spherical in form and had a total mass of 1,400 kg. It consisted of two sections: the main section, which contained the guidance and targeting, computational and optical homing systems, and the 300 kg explosive charge; and the engine section. The body of the interceptor was designed so that after the explosion it would fragment into 12 groups of shrapnel. The specified radius of guaranteed target destruction was 1 km. However in a head-on intercept, only 400 m radius was guaranteed, while in a chase intercept, a 2 km radius of destruction could be achieved. The engine was capable of numerous quick starts and restarts, with a total operating time of 300 seconds.

Cosmos 185, along with its carrier rocket, maneuvered from a low orbit to a higher one. The carrier rocket was abandoned sometime after the maneuver.
