Associated space launch
US-A (Upravlenniye Sputnik Aktivny) were active radar satellites for ocean surveillance. The high power consumtion of the active radar required a nuclear reactor as power source. The satellites were known as RORSAT in the west. The US-AO series consisted of satellites, which tested all the system components but the nuclear reactor. They were battery powered.
COSMOS 198 was lifted into orbit during the mission ‘Tsiklon-2A | US-AO 3’, on board a Tsiklon-2A space rocket.
The launch took place on Dec. 27, 1967, 11:28 a.m. from 90/19.
