Tupolev Tu-22M Backfire
From Canadian Power Wiki
The Tupolev Tu-22M (Russian: Туполев Ту-22М; 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 Russia, China and India, and as of 2014 nearly 200 Tu-22Ms are in use.
Variants[edit | edit source]
- Tu-22M0: Earliest pre-production variant, 9 were produced.
- Tu-22M1: Pilot-production aircraft, 9 were produced in 1971 and 1972. Its NATO reporting name was Backfire-A.
- Tu-22M2: The first major production version, entering production in 1972, was the Tu-22M2 (NATO: Backfire-B), with longer wings and an extensively redesigned, area ruled fuselage (raising the crew complement to four), twin NK-22 engines (215 kN thrust each) with F-4 Phantom II-style intake ramps, and new undercarriage with the main landing gear in the wing glove rather than in large pods. 211 Tu-22M2 were built from 1972 into 1983. The Tu-22M2 had a top speed of Mach 1.65 and was armed most commonly with long-range cruise missiles/anti-ship missiles, typically one or two Raduga Kh-22 anti-shipping missiles. Some Tu-22M2s were later reequipped with more powerful NK-23 engines and redesignated Tu-22M2Ye.
- Tu-22M3: The later Tu-22M3 (NATO: Backfire-C), which first flew in 1977, introduced into operations in 1983 and officially entered service in 1989, had new NK-25 engines with substantially more power, wedge-shaped intake ramps similar to the MiG-25, wings with greater maximum sweep and a recontoured nose housing a new Leninets PN-AD radar and NK-45 nav/attack system, which provides much-improved low-altitude flight. The aerodynamic changes increased its top speed to Mach 2.05 and its range by one third compared to the Tu-22M2. It has a revised tail turret with a single cannon, and provision for an internal rotary launcher for the Raduga Kh-15 missile, similar to the American AGM-69 SRAM. It was nicknamed Troika ('Trio' or third) in Russian service. 268 were built until 1993. As built, the Tu-22M included the provision for a retractable probe in the upper part of the nose for aerial refueling. The probe was reportedly removed as a result of the SALT negotiations, because with refueling it was considered an intercontinental range strategic bomber. The probe can be reinstated if needed. Tu-22M3s used to attack targets in Syria underwent modernization, during which the SVP-24 specialized computing subsystems were installed on them, significantly increased the accuracy of the bombing. 5 modernized aircraft entered service in 2015, 2 more in 2017. One more in 2018.
- Tu-22M3 with SVP-24-22: Modernized Tu-22M3 of the Russian Air Force fitted with a new sighting and computing system SVP-24-22 Gefest, instead of the NK-45 Vakhta-2 complex. The SVP-24-22 includes a new and more powerful onboard computer SV-24, UVV-MP-22 input-output device, flight information generation unit – BFI, aviation collimator indicator KAI-24, radio navigation system SRNS-24 with the A737 satellite receiver and the solid-state information storage device TBN-K-2 to save data of the navigation-targeting complex SVP-24-22 and of the flight recorder. Five modernized aircraft entered service in 2015, two in 2017, one in 2018, and two in 2019.
- Tu-22M3M: Tu-22M3 for the Russian Air Force with upgraded avionics and the ability to use precision air-to-surface weapons. Prior to 2020 it is planned to upgrade thirty Tu-22M3 with new hardware components and adapted for the extended range weapons. Can carry twelve Kh-15 or three Kh-22 missiles. The first flight is scheduled for August 2018.
- Tu-22M4: The development of the "Izdeliye 4510" began in 1983. Modernization with the installation of new engines NK-32 (from Tu-160) and with a change in engine air intakes. Modernization of avionics by installing a new PNK, radar "Overview" (from Tu-160), EW complex. Expansion of the range of weapons: three Kh-32 or ten Kh-15 (with placement on six internal and four external points of suspension) or UPAB-1500 with a television guidance system. In 1990, a prototype was built at the Kazan aircraft factory. Works in this direction were discontinued in November 1991. The prototype aircraft No. 4504 is in the museum exposition of the AB Dyagilevo.
- Tu-22M4IQ: Export variant for the Iraqi Air Force
- Tu-22MR: Several Tu-22M3s, perhaps 12, were converted to Tu-22M3(R) or Tu-22MR standard with Shompol side looking airborne radar and other ELINT equipment.
- Tu-22DP: The Tu-22DP (Dal'nego Perekhvata, long-range interception)/ DP-1 is a long-range interceptor project based on the Tu-22M2 (later on the basis of the Tu-22M3). R & D was conducted by the AN Tupolev Design Bureau together with GosNIIAS. It was assumed that the DP could also carry strike weapons.
- Tu-344: A canceled civilian supersonic aircraft based on the Tu-22M3, designed to carry 10–12 passengers. Developed by Tupolev Design Bureau (ANTK named after A. Tupolev) within the framework of conversion program in the second half of the 1990s. The development of the aircraft began in the 1990s with the emergence of interest and demand for supersonic business jets (SBJ). Since the creation of an aircraft from scratch requires a large investment, Tupolev Design Bureau decided to create an SBJ-class aircraft based on Tu-22M3. However, the project proved to be unpromising at the time, as the aircraft was supposed to be used internationally, but did not meet international environmental standards of the day.
