Summary
US-AO 3 launched on a Soviet Space Program Tsiklon-2A from 90/19, Baikonur Cosmodrome, Republic of Kazakhstan on December 27, 1967. It was Soviet Space Program's 289th launch, 74th this year and humanity's 788th orbital launch attempt. It was the 2nd Tsiklon-2A flight. The payload was bound for low Earth orbit (LEO). Kosmos-198 ROCh, one of 3 catalogued objects, reached a 272 × 276 km orbit inclined 65.1°. 3 objects from this launch are catalogued, one of them a payload.

About this 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.
