A versatile design, the Tu-16 was built in numerous specialized variants for aerial reconnaissance, maritime surveillance, electronic intelligence gathering (ELINT), and electronic warfare (ECM). A total of 1,507 aircraft were constructed in three plants in the Soviet Union, in 1954–1962. A civilian adaptation, the Tupolev Tu-104, saw passenger service with Aeroflot. The Tu-16 was also exported to Indonesia, Egypt, and Iraq. It continued to be used by the Air Forces and naval aviation of the Soviet Union and subsequently Russia, until 1993.
