JUST LISTEN THOSE ENGINES SCREAMING...
The Tupolev Tu-22M (NATO reporting name "Backfire") is a supersonic, swing-wing, long-range strategic and maritime strike bomber developed by the Soviet Union. Significant numbers remain in service with the Russian Air Force.The Tu-22 'Blinder' had not proved particularly successful, in some respects being inferior to the earlier Tu-16 'Badger'. Its range and take-off performance, in particular, were definite weak points. Even as the 'Blinder' was entering service, OKB Tupolev began work on an improved successor.
As with the contemporary Mikoyan-Gurevich MiG-23 'Flogger' and Sukhoi Su-17 'Fitter' projects, the advantages of variable-geometry wings seemed attractive, allowing a combination of short take-off performance, efficient cruising, and good high-speed, low-level ride. The result was a new swing-wing aircraft called Samolet 145, derived from the Tu-22, with some features borrowed from the abortive Tu-98 'Backfin'.
The first prototype, Tu-22M0, first flew 30 August 1969. The resultant aircraft was first seen by NATO around that time. For several years it was believed in the West that its service designation was Tu-26. During the SALT negotiations of the 1980s the Soviets insisted it was the Tu-22M. At the time, Western authorities suspected that the misleading designation was intended to suggest that it was simply a derivative of the Tu-22 rather than the far more advanced and capable weapon it actually was. It now appears that Tu-22M was indeed the correct designation, and the linkage to the earlier Tu-22 was intended by Tupolev to convince the Soviet government that it was an economical follow-on to the earlier aircraft. Actually, the fore gear leg and the bomb bay cover were inherited from the original Tu-22. (Much the same happened in the U.S. in the 1950s with aircraft like the Lockheed F-94C Starfire, originally F-97, and the North American F-86D Sabre, originally the F-95.)The first major production version, entering production 1972, was the Tu-22M2 ('Backfire-B'), with longer wings and an extensively redesigned, area ruled fuselage (raising the crew complement to four), twin NK-22 engines with F-4 Phantom II-style intakes, and new undercarriage carrying the landing gear in the wing glove rather than in large pods. These were most commonly armed with long-range cruise missiles/anti-ship missiles, typically one or two AS-4 'Kitchen' anti-shipping missiles. Some Tu-22M2s were later requipped with more powerful NK-23 engines and redesignated Tu-22M2Ye. In service, the Tu-22M2 was known to its crews as Dvoika ('Deuce'). It was more popular than the Tu-22, thanks to its superior performance and improved cockpit, but its comfort and reliability still left much to be desired. The later Tu-22M3 (NATO 'Backfire C'), which first flew in 1976 and entered service in 1983, had new NK-25 engines with substantially more power, wedge-shaped intakes 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 (although not true nap-of-the-earth flying). It had a revised tail turret with a single cannon, and provision for an internal rotary launcher for the AS-16 'Kickback' missile, similar to the American AGM-69 SRAM. The new aircraft had much better performance than the -M2. It was nicknamed Troika ('Trio'), although apparently it is sometimes referred to as 'Backfire' in Russian service.

The Antonov An-70 is a next-generation four-engine medium-distance transport aircraft, and the first large aircraft to be powered by propfan engines. Developed by the Antonov design bureau to replace the obsolete An-12 military transport, work on the An-70 began in the early 1990s.
Maiden flight of the first prototype took place on December 16, 1994 in Kiev, Ukraine.Russia and Ukraine had as of 2002 agreed on a 50-50 risk-sharing deal on production. Particularly, there were plans to establish serial production of the model in both Kiev and Samara, Russia, guaranteeing employment of about 80,000 people in two countries. The Russian government had shown interest in purchasing 160 planes for its military.The first prototype was lost in 1995 in a mid-air collision with an Antonov 72 chase aircraft. The second prototype suffered damage in a 2001 emergency landing during cold weather testing in Russia, but was repaired. Soon after the first crash, Russian authorities started to question the An-70's abilities and demanded further development.
In May 2005, senior officials of Russian Air Force claimed that bilateral development and further testing of the plane continue, though inside sources (Piort Butowski) reported that the An-70 was rapidly losing ground to the upgraded IL-76MF, with the Tu-330 and IL-214 coming up strongly on the outside. In November 2005, Ukraine's Defence Ministry announced plans to buy five AN-70s for the Ukrainian Air Force. In December 2005, Antonov maintained that production of the aircraft remains a priority.
In April 2006, Russia announced its complete withdrawal from the project. The head of the Russian Air Force, Vladimir Mikhailov, claimed that the An-70 has grown into a heavy, expensive cargo plane. The military plans to use the Ilyushin Il-76MF, which reportedly costs half as much as the An-70. After the Orange Revolution in late 2004, and with Ukraine openly aiming for NATO membership, political will for the project evaporated. Russia has provided around 60 per cent of the estimated USD 5 billion invested in the project to date.Fully fly-by-wire, the An-70 features a glass cockpit and uses composite materials throughout. It is powered by four Progress D-27 Propfans, each turning a pair of contra-rotating Scimitar propeller propfans, and reaches 90% efficiency (claimed) in cruise at jet speeds.

The Sukhoi Su-24 (NATO reporting name Fencer) was the Soviet Union's most advanced all-wea
The Sukhoi Su-24 (NATO reporting name Fencer) was the Soviet Union's most advanced all-weather interdiction and attack aircraft in the 1970s and 1980s. The two-seat, twin-engined aircraft carried the USSR's first integrated digital nav/attack system. In many aspects, the Su-24's configurations is similar to F-111. It remains in service with the Russian Air Force and various export nations.One of the conditions for accepting Sukhoi Su-7B into service in 1961 was the requirement for Sukhoi to develop an all-weather variant capable of precision airstrikes. Preliminary investigations with S-28 and S-32 aircraft revealed that the basic Su-7 design was too small to contain all the avionics required for the mission.OKB-794 was tasked with developing an advanced nav/attack system, codenamed Puma, which would be at the core of the new aircraft.In 1962-1963, Sukhoi designed and built a mockup of S-6, a delta wing aircraft powered by two Tumansky R-21F-300 turbojet engines and with a crew of two in a tandem arrangement. The mockup was inspected but no further work was ordered due to lack of progress on the Puma hardware.In 1964, Sukhoi started work on S-58M. The aircraft was supposed to represent a modification of the Sukhoi Su-15 interceptor (factory designation S-58). In the meantime, revised Soviet Air Force requirements called for a low-altitude strike aircraft with STOL capability. A key feature was the ability to cruise at supersonic speeds at low altitude for extended periods of time in order to traverse enemy air defenses.To achieve this, the aircraft was expected to utilize two Tumansky R-27F-300 afterburning turbojets for cruise and four Kolesov RD-36-25 turbojets for STOL performance. Side-by-side seating for the crew was implemented since the large Orion radar antennae required a large frontal cross-section.To test the six-engine scheme, the first Su-15 prototype was converted into S-58VD flying laboratory which operated in 1966-1969.The aircraft was officially sanctioned on 24 August 1965 under the internal codename T-6. The first prototype, T-6-1 was completed in May 1967 and flew on 2 July with V. S. Ilyushin at the controls.The initial flights were performed without the four lift engines which were finally installed in October 1967. At the same time, R-27s were replaced with Lyulka AL-21Fs. STOL tests confirmed the data from S-58VD that short-field performance was achieved at the cost of significant loss of flight distance as the lift engines occupied space normally reserved for fuel. In addition, the use of lift engines precluded underfuselage hardpoints and the aircraft was difficult to control during transition from STOL to conventional flight.On 7 August 1968, the OKB was officially tasked with investigating a variable geometry wing for the T-6. The resulting T-6-2I first flew on 17 January 1970 with Ilyushin at the controls. The subsequent government trials lasted until 1974, dictated by the complexity of the on-board systems.The all-weather capability was achieved thanks to the aforementioned Puma nav/attack system operating in conjunction with Orion-A attack radar, Relyef terrain radar, and Orbita-10-58 computer. The crew was equipped with zero-zero Zvezda K-36D ejection seats. * Crew: Two (pilot and weapons system operator) * Length: 22.53 m (73 ft 11 in) * Wingspan: 17.64 m extended, 10.37 m maximum sweep (57 ft 10 in / 34 ft 0 in) * Height: 6.19 m (20 ft 4 in) * Wing area: 55.2 m² (594 ft²) * Empty weight: 22300 kg (49,165 lb) * Loaded weight: 38040 kg (83,865 lb) * Max takeoff weight: 43755 kg (96,505 lb) * Powerplant: 2× Saturn/Lyulka AL-21F-3A turbojets o Dry thrust: 75 kN (16,860 lbf) each o Thrust with afterburner: 109.8 kN (24,675 lbf) each * *Fuel capacity: 11100 kg (24,470 lb)
