One currently prepared upgrade will cover the Tu-22M3 `Backfire-C', the service life of which can be prolonged until 2010. The modernised version will be designated the Tu-22M5 (the designation Tu-22M4 was used in 1990 for a prototype that never entered serial production); ..This upgrade will replace both equipment and armament; among others the Tu-22M5 will obtain a new Fazotron-NIIR radar enabling automatic terrain-following and avoidance. Also, the navigation and self-defence systems will be modernised, although no information is available about possible changes in the airframe or the replacement of engines. Such changes, however, are hardly probable.
The Tu-22M5's armament will be expanded by the subsonic Kh-101 (up to four) and Kh-SD (six to eight) cruise missiles. No information is available about other possible armaments, but the aircraft will probably also obtain supersonic missiles to replace its current Kh-22 anti-ship missiles (ASMs). One to three Kh-22s are now a basic armament of the Tu-22M3, used mainly as it is in countering capital warships. The missile has a range of 550km and a speed of Mach 3; it cannot be completely replaced by subsonic Kh-SDs. However, since the Kh-22 came into being as early as at the late 1950s/early 1960s, it makes sense to expect a successor to be carried in the Tu-22M5.
