1966 September 17 - 22:35 GMT - Launch Vehicle: Tsiklon. LV Model: R-36-O . R-36O 8K69 U22502 No. 05L OGCh Mass: 1,700 kg (3,700 lb). Spacecraft: OGCh. Agency: RVSN. Perigee: 138 km (85 mi). Apogee: 792 km (492 mi). Inclination: 49.60 deg. Period: 93.90 min. First attempted orbital Fractional Orbital Bombardment System test. The second stage of the booster placed the third stage and dummy warhead into a 214 km x 523 km parking orbit. altitude. The third stage was evidently wrongly oriented, and instead of braking the warhead into an impact at Kapustin Yar, boosted it into a higher 280 km x 1,010 km orbit. The dummy warhead seperated but was commanded to self destruct, resulting in over 100 catalogued orbiting objects.

Apogee: 767 km (476 mi). Inclination: 49.10 deg. Period: 97.43 min. Second attempted orbital Fractional Orbital Bombardment System test. failure - self destruct charge was detonated, resulting in 50 catalogued orbiting objects. No impact of the dummy warhead in the Kapustin Yar impact zone.
