Pivan-1

Pivan-1 (Russian: Пивань-1) is a military townlet near Komsomolsk-na-Amur in Khabarovsk Krai in the Russian Far East which is the location of the eastern control centre for Russia's Oko satellites. These give early warning of ballistic missile launches, mainly from the continental United States. The site is part of the Main Centre for Missile Attack Warning and information from here is processed at the Russian Aerospace Defence Forces centre in Solnechnogorsk and could be used, together with early warning radar such as the Voronezh, for launch on warning or the A-135 anti-ballistic missile system. A similar facility is located at Serpukhov-15 near Moscow.

The name Pivan-1 is a code name following the practice established to name closed cities and military facilities. It is named after the nearest settlement, Pivan.
