Legenda (satellite system)

Legenda, or the MKRC Legenda system, is a Soviet satellite targeting system mated to the SS-N-19 missile. It consisted of the US-P SIGINT satellites and the US-A Radar Ocean reconnaissance satellites, which were nuclear powered.[1] The Legenda system consists of 37 ELINT satellites named US-P [2] and 32 US-A nuclear powered radar satellites [3] to provide global coverage. Legenda is now non-functional after the US-A and US-P satellites were deactivated. It is being replaced by the Liana system with 4 operational satellites as of July 2021.[4]
