The Sukhoi Su-24 ( Russian Сухой Су-24 , NATO code name : Fencer , in German Fechter ) is a two-seat tactical bomber (front bomber) that was developed in the Soviet Union . After his service with the Soviet Air Force , he is still used today by the Russian Air Force and the air forces of other countries. The pilots sit next to each other as in the US model F-111 .
development
In the mid-1960s, the Soviet front-line aircraft were looking for a successor to the now outdated Jak-28 . After the drafts S-6 with conventional swept wings and T-6 with double delta wings and four lift engines in the fuselage, whose prototype T-6-1 flew for the first time on July 2, 1967, designer Jewgeni S. Felsner decided on a solution at the end of 1967 with swivel blades . The reasons were the poor flight characteristics and the insufficient payload and range of the T-6-1. Their concept was directly influenced by the US TFX program that led to the F-111 . The Soviet Air Force requested an aircraft with similar capabilities, assuming that the flight characteristics were due to the swivel-wing design. The prototype T-6-2I was flown for the first time on January 17, 1970 by Vladimir S. Ilyushin . As the tests were successful, the first Su-24 series machine was completed in December 1971 at the Chkalov plant in Novosibirsk. This had a modified rear compared to the prototype and optimized air inlets. In 1973 the first task force of the air force and in 1975 the navy were equipped with the much more powerful but also more complex machine than its predecessors.
The Su-24 fills the role of a low-flying, all-weather ground attack aircraft . The Su-24 can also be used from makeshift airfields .
The Soviet assumptions turned out to be correct - the Su-24 turned out to be a powerful fighter aircraft, with good range, variable armament (distributed over eight suspension points; four lower fuselage and four lower wing stations) through to nuclear free-fall bombs, advanced electronic defense ( Eloka ) and early warning systems.
Due to its robustness, it is still very popular in export and can be reproduced on request.
Ten aircraft were lost during the testing and development of the Su-24. Eight pilots who rescued themselves with the ejection seat survived and 13 died. No other aircraft made by the Sukhoi design office suffered such high losses during testing as the Su-24.
After a series of breakdowns, the Russian Air Force announced in 2012 that it would take all machines of this type out of service by 2020.
Versions
The following versions were built or planned:
- Su-24 up to Series 4 ("Fencer-A"): early series version with a long fuel drain pipe at the end of the engines and adjustment ramps on the air inlets for high speed at high altitudes
- Su-24 series 4 to 11 ("Fencer-A"): Problems with the air inlets of the first series were solved by enlarging them from series 4; the adjustment ramps in the air inlets were no longer used to save weight; Although this reduced the top speed from Mach 2.18 to Mach 1.35, the low-level flight characteristics were not significantly impaired.
- Su-24 series 12 to 15 ("Fencer-B"): performance-enhanced cooling system, recognizable by an air scoop on the fuselage; modified sensor group under the front fuselage; wider vertical tail; shortened fuel drain pipe at the end of the engines; a third suspension point under the hull
- Su-24 series 16 to 24 ("Fencer-C"): the shape of the rear fuselage more closely followed the engines; a braking parachute was located at the base of the vertical stabilizer ; an additional air intake for the cooling system was installed at the front edge of the vertical stabilizer; from the 26th series 21 aircraft, the air inlets are no longer adjustable, which limited the top speed to Mach 1.35, but reduced the empty weight; at the same time the wing profile was changed
- Su-24 series 24 to 27 ("Fencer-C"): Installation of triangular radar warning receivers at the air inlets of the engines in front of the wing box and on both sides at the upper end of the vertical stabilizer;
- Su-24M ("Fencer-D"): upgraded version of the Su-24; retractable air refueling probe, new avionics complex for the use of new laser and television-guided weapons, modified nose for a new nose radar, laser lighting and TV target tracking system of the type Kajra-24 in the glazed housing in the middle under the front fuselage and terrain tracking radar coupled with the autopilot for low-level flight operations; First flight on June 29, 1977
- Su-24M ("Fencer-D Mod"): Possibility to carry an air refueling container for air-to-air refueling on the central suspension under the fuselage by integrating large boundary layer fences with pylon, improved countermeasure systems (more chaff throwers)
- Su-24BM : unrealized enlarged version of the Su-24M with an internal weapon bay in the fuselage between the engines
- Su-24MM : unrealized version of the Su-24M with the Ljulka AL-31 engines
- Su-24MK ("Fencer-D"): modified export version of the Su-24M with reduced avionics; First flight in 1987
- Su-24MR ("Fencer-E"): Version of the Su-24M as a tactical reconnaissance aircraft with sensors (e.g. side-view radar ) and cameras installed internally and externally in containers ; without a 23 mm cannon; First flight in September 1980
- Su-24MP ("Fencer-F"): Version of the Su-24M for electronic warfare ; First flight in April 1980
- Su-24K : unrealized version of the Su-24 for use on aircraft carriers because the Su-24 was too heavy
- Su-24bis : Study of a much improved version with the latest avionics and armament; The model was shown at the Berlin exhibition ILA 2000
- Su-24M2 : modernized version of the Su-24M or Su-24MK with improved avionics (including GPS or the Russian equivalent GLONASS , head-up display (HUD) and helmet visor) and more modern armament, in the case of the export variant also western ones Armament; real all-weather version for day and night use
- Su-24MK2 : Version of the Su-24M2 for Algeria
- Su-24MRK2 : modernized version of the Su-24MR for Algeria based on the Su-24M2

Self-defense systems
Radar detector
Behind the air inlets in front of the wings there is a "Berjoscha" -SPO-10- and in the slat there is a SPO-15C radar detector . In addition, an SPO-15C and an SPO-10 radar warning receiver are housed in the tail fin and above the parachute container.
Missile approach warning
The Asowsky L-082 MAK-UL missile approach warning sensor (MAWS), which searches for infrared emissions, is installed in a ball in the front bulge of the fuselage.
Decoys dispenser
At the beginning of the horizontal fins, a Gorizont-AAP-50MA decoy launcher (rectangular container for each 12 × 50 mm heat flare decoys ) is built into the fuselage on each side . In addition, other elongated AAP-50MR decoys can be installed instead of the boundary layer fence.
Electronic warfare systems
The Filin-N defense system receives the information from the radar warning sensors SPO-15 and controls the EKF jammer SPS-61 if necessary. The active radar jammer Geran-F is also integrated in the system. The AAP-50 flare launchers are also triggered automatically when required. Starting with the Su-24M, the improved Karpaty system with the MAK-IR-Warner is installed.
