Sukhoi Su-24 "Fencer" Ukrainian Air Force

Back


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) # Maximum speed: 1,315 km/h (710 knots, 815 mph, Mach 1.07) at sea level; Mach 1.35 at high altitude # Range: 615 km in a lo-lo-lo attack mission with 3000 kg (6,615 lb) ordnance and external tanks (330 nm, 380 mi) # Ferry range: 2775 km (1,500 nm, 1,725 mi) # Service ceiling: 11000 m (36,090 ft) # Rate of climb: 150 m/s (29,530 ft/min) The Ukrainian Air Force (Ukrainian: Повітряні Сили України, Povitryani Syly Ukrayiny) is a part of the Armed Forces of Ukraine. Ukrainian Air Force Command and headquarters are located in the city of Vinnytsia.The primary tasks of the Air Force of Ukraine are: winning operational air superiority, delivering air strikes against enemy units and facilities, covering troops against enemy air strikes, providing air support to the Land Force and the Navy, disrupting enemy military and state management, damaging and destroying enemy communication, and providing support by air in the form of reconnaissance, air drops, troops and cargo transportation.
