US-A (Upravlenniye Sputnik Aktivny) were active radar satellites for ocean
surveilance. 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-A-Test series consisted of satellites, which tested all the system
components, but have not a nuclear reactor. They were battery powered.
