The Tupolev Tu-22M (Russian: ??????? ??-22?; NATO reporting name: Backfire) is a
supersonic, variable-sweep wing, long-range strategic and maritime strike bomber
developed by the Tupolev Design Bureau. According to some sources, the bomber
was believed to be designated Tu-26 at one time.
During the Cold War, the Tu-22M was operated by the Soviet Air Force (VVS) in a
strategic bombing role, and by the Soviet Naval Aviation (Aviacija
Vojenno-Morskogo Flota, AVMF) in a long-range maritime anti-shipping role.
Significant numbers remain in service with the Russian Air Force, and as of 2014
more than 100 Tu-22Ms are in use.
In 1962, with the introduction of the Tu-22, it became increasingly clear that
the aircraft was considerably inadequate in its role as a bomber. In addition to
characteristics proved to be dangerous. Its landing speed was some 100 km/h (60
mph) greater than previous bombers and it had a tendency to pitch up and strike
its tail upon landing. It was difficult to fly, and had poor all-round
visibility. In 1962, Tupolev commenced work on major update of the Tu-22.
Initially, the bureau planned to add a variable-sweep wing and uprated engines
Zhukovsky
During this time, Sukhoi, traditionally a designer of fighter aircraft,
developed the T-4, a four-engine titanium aircraft with canards. A response to
the XB-70, it was to have a cruise speed of 3,200 km/h (2,000 mph), requiring a
massive research effort in order to develop the requisite technologies. Not to
be outdone, Tupolev, whose expertise is with bombers, offered the Soviet Air
Force (Voyenno-Vozdushnye Sily, VVS) a massively-updated version of the Tu-22.
Compared to the T-4, it was evolutionary design, and thus its appeal laid in its
simplicity and low cost. However, the Soviet government was sceptical about the
need to approve the development of a replacement aircraft so soon after the
Tu-22 had just entered service.[7] The Air Force and Tupolev, in order to save
criticisms from the ICBM lobby, agreed to pass off the design as an update of
the Tu-22 in their discussions with the government. The aircraft was designated
Tu-22M, given the OKB code "Aircraft 45", and an internal designation of "AM".

US intelligence had been aware of the existence of the aircraft since 1969, and
the first satellite photograph of the bomber would be taken in 1970. The
existence of the aircraft was a shock to US intelligence as Nikita Kruschev, who
had been the Soviet premier up to 1964, was adamant that ICBMs would render the
bomber obsolete.

The Tu-22M was first used in combat in Afghanistan. It was deployed December
1987 to January 1988, during which the aircraft flew strike missions in support
of the Soviet Army's attempt to relieve the Mujahideens' siege against the city
of Khost. Two squadrons of aircraft from the 185th GvBAP based at Poltava were
deployed to Maryy-2 air base in Turkmenistan. Capable of dropping large tonnages
of conventional ordnance, the aircraft bombed enemy forts, bases and material
supplies.[18] In October 1988, the aircraft was again deployed against the
Mujahideen. Sixteen Tu-22M3s were used to provide cover to Soviet forces that
were pulling out of the country. The Tu-22Ms were tasked with destroying paths
of access to Soviet forces, attacking enemy forces at night to prevent
regrouping, and to attack incoming supplies from Iran and Pakistan. Working
alongside 30 newly-arrived MiG-27s, the aircraft also from flew missions aimed
at relieving the besieged city of Kandahar.[19][20] The aircraft had its last
Afghan operation in January 1989 at Salang pass.[21]
The Tu-22M suffered from widespread maintenance issues during its service with
the Soviet forces. These stemmed from poor manufacturing quality. The engines
and airframes in particular had low service lives.[22] The Air Force at one
point sought to have Tupolev prosecuted for allegedly rushing the inadequate
designs of the Tu-22M and the Tu-160 into service.[23] This was compounded by
the government bureaucracy, which hampered the provision of spare parts to allow
the servicing of the Tu-22M. With some aircraft grounded for up to six months,
