P-801 1, ..., 7 ("Subsatellite Ferret C")

The P-801 (or Program 801) satellites were a special series among the so called "Subsatellite Ferrets", low orbit ELINT/SIGINT satellites to pinpoint and characterize different Radar emitters in the Soviet Union and Warsaw pact states. Before their program name was known, they are referred to as "Subsatellite Ferret C" (SSF-C).

The P-801 type satellites operated from a higher orbit (12001400 km at about 80.3 to 96.9) than the P-11 satellites to monitor the ABM radars at Tallinn.

Reportedly the P-801 type subsatellite ferrets were used in conjunction under the code name Yield and later Willow with the large Jumpseat ELINT satellites, which operated from Molniya-orbits.

These subsatellites were deployed from the propulsion rack of the Agena-D stage of KH-4A Corona, KH-4B Corona reconnaissance satellites and racks mounted on the KH-9 Hexagon reconnaissance satellites. They used two solid-fuel kick-motors to maneuver themselves into their operational orbits after deployment.

A satellite with a similar orbit is P-226 1, which might represent an modified version or just a new designation.
