Matrosovo is a former airport, likely air base, on Sakhalin Island, Russia located 14 km north of Leonidovo. It served as a dispersal airfield for military aircraft on Sakhalin Island during the Cold War.
Matrosovo was identified by U.S. photographic reconnaissance satellites around 1962.[1] The Central Intelligence Agency's collection of declassified documents do not show that any aircraft were ever observed at this airfield, and no documents after 1970 reference the airfield.
In 1985 a Tupolev Tu-16 from Khorol crashed at or near this airfield. Matrosovo was not used after the Cold War and has fallen into a state of decay.
