The Sukhoi
Sukhoi
Su-25 Grach (Russian: Грач (rook); NATO
NATO
reporting name: Frogfoot) is a single-seat, twin-engine jet aircraft developed in the Soviet Union
Soviet Union
by Sukhoi. It was designed to provide close air support for the Soviet Ground Forces. The first prototype made its maiden flight on 22 February 1975. After testing, the aircraft went into series production in 1978 at Tbilisi

in the Georgian Soviet Socialist Republic. Early variants included the Su-25UB two-seat trainer, the Su-25BM for target-towing, and the Su-25K for export customers. Some aircraft were being upgraded to Su-25SM standard in 2012. The Su-25T and the Su-25TM (also known as the Su-39) were further developments, not produced in significant numbers. The Su-25, and the Su-34, were the only armoured, fixed-wing aircraft in production in 2007.[1] Su-25s are in service with Russia, other CIS members, and export customers. The type has seen combat in several conflicts during its more than 30 years in service. It was heavily involved in the Soviet war in Afghanistan, flying counter-insurgency missions against the Mujahideen. The Iraqi Air Force

Development In early 1968, the Soviet Ministry of Defence decided to develop a specialised shturmovik armoured assault aircraft in order to provide close air support for the Soviet Ground Forces. The idea of creating a ground-support aircraft came about after analysing the experience of ground-attack (shturmovaya) aviation during the 1940s, 1950s, and 1960s.[2] The Soviet fighter-bombers in service or under development at the time (Su-7, Su-17, MiG-21
MiG-21
and MiG-23) did not meet the requirements for close air support of the army.[2] They lacked essential armour plating to protect the pilot and vital equipment from ground fire and missile hits, and their high flight speeds made it difficult for the pilot to maintain visual contact with a target. Having taken into account these problems, Pavel Sukhoi
Sukhoi
and a group of leading specialists in the Sukhoi
Sukhoi
Design Bureau started preliminary design work in a comparatively short period of time, with the assistance of leading institutes of the Ministry of the Aviation Industry and the Ministry of Defence.[3]

In March 1969, a competition was announced by the Soviet Air Force that called for designs for a new battlefield close-support aircraft. Participants in the competition were the Sukhoi
Sukhoi
design bureau and the design bureaus of Yakovlev, Ilyushin
Ilyushin
and Mikoyan.[4] Sukhoi
Sukhoi
finalised its "T-8" design in late 1968, and began in work on the first two prototypes (T8-1 and T8-2) in January 1972. The T8-1, the first airframe to be assembled, was completed on 9 May 1974. Another source says November 1974. However, it did not make its first flight until 22 February 1975, after a long series of test flights by Vladimir Ilyushin. The Su-25 surpassed its main competitor in the Soviet Air Force competition, the Ilyushin
Ilyushin
Il-102, and series production was announced by the Ministry of Defence.[5][6] During flight-testing phases of the T8-1 and T8-2 prototypes' development, the Sukhoi
Sukhoi
Design Bureau's management proposed that the series production of the Su-25 should start at Factory No. 31 in Tbilisi, Soviet Republic of Georgia, which at that time was the major manufacturing base for the MiG-21UM "Mongol-B" trainer. After negotiations and completion of all stages of the state trials, the Soviet Ministry of Aircraft Production authorised manufacture of the Su-25 at Tbilisi, allowing series production to start in 1978.[7] In the late 1980s and early 1990s, several Su-25 variants appeared, including modernised versions, and variants for specialised roles. The most significant designs were the Su-25UB dual-seat trainer, the Su-25BM target-towing variant, and the Su-25T for antitank missions. In addition, an Su-25KM prototype was developed by Georgia in co-operation with Israeli company Elbit Systems
Elbit Systems
in 2001, but so far this variant has not achieved much commercial success. As of 2007[update], the Su-25 was the only armoured aircraft still in production.[1] The Russian Air Force, which operates the largest number of Su-25s, planned to upgrade older aircraft to the Su-25SM variant, but funding shortfalls had slowed the progress; by early 2007 only seven aircraft had been modified.[8] Design Overview The Su-25 has a conventional aerodynamic layout with a shoulder-mounted trapezoidal wing and a traditional tailplane and rudder. Several metals are used in the construction of the airframe: 60% aluminium, 19% steel, 13.5% titanium, 2% magnesium alloy and 5.5% other materials.[9]

Su-25 at Kubinka air base

All versions of the Su-25 have a metal cantilever wing, of moderate sweep, high aspect ratio and equipped with high-lift devices. The wing consists of two cantilever sections attached to a central torsion box, forming a single unit with the fuselage. The air brakes are housed in fairings at the tip of each wing. Each wing has five hardpoints for weapons carriage, with the attachment points mounted on load-bearing ribs and spars.[10] Each wing also features a five-section leading edge slat, a two-section flap and an aileron. The flaps are mounted by steel sliders and rollers, attached to brackets on the rear spar. The trapezoidal ailerons are near the wingtips.[11] The fuselage of the Su-25 has an ellipsoidal section and is of semi-monocoque, stressed-skin construction, arranged as a longitudinal load-bearing framework of longerons, beams and stringers, with a transverse load-bearing assembly of frames.[9] The one-piece horizontal tailplane is attached to the load-bearing frame at two mounting points.[11] Early versions of the Su-25 were equipped with two R95Sh non-afterburning turbojets, in compartments on either side of the rear fuselage. The engines, sub-assemblies and surrounding fuselage are cooled by air provided by the cold air intakes on top of the engine nacelles. A drainage system collects oil, hydraulic fluid residues and fuel from the engines after flight or after an unsuccessful start. The engine control systems allows independent operation of each engine.[11] The latest versions (Su-25T and TM) are equipped with improved R-195 engines.[12]

Nose view of the Su-25

The cannon is in a compartment beneath the cockpit, mounted on a load-bearing beam attached to the cockpit floor and the forward fuselage support structure. The nose is fitted with distinctive twin pitot probes and hinges up for service access.[9] Cockpit The pilot flies the aircraft by means of a centre stick and left hand throttles. The pilot sits on a Zvezda K-36 ejection seat (similar to the Sukhoi
Sukhoi
Su-27) and has standard flight instruments. At the rear of the cockpit is a 6 mm (0.24 in) thick steel headrest, mounted on the rear bulkhead. The cockpit has a bathtub-shaped armoured enclosure of welded titanium sheets, with transit ports in the walls. Guide rails for the ejection seat are mounted on the rear wall of the cockpit.[9] The canopy hinges open to the right and the pilot enters using the flip-down ladder. Once inside, the pilot sits low in the cockpit, protected by the bathtub assembly, which makes for a cramped cockpit. Visibility from the cockpit is limited, being a trade-off for improved pilot protection. Rearwards visibility is poor and a periscope is fitted on top of the canopy to compensate.[13] A folding ladder built into the left fuselage provides access to the cockpit as well as to the top of the aircraft. Avionics The base model Su-25 incorporates a number of key avionics systems. It has no TV guidance but includes a distinctive nose-mounted laser rangefinder, that is thought to provide for laser-based target finding.[13][14] A DISS-7 doppler radar is used for navigation; the Su-25 can fly at night, in visual and instrument meteorological conditions. The Su-25 often has radios installed for air-to-ground and air-to-air communications, including an SO-69 identification-friend-or-foe (IFF) transponder. The aircraft's self-defence suite includes various measures, such as flare and chaff dispensers capable of launching up to 250 flares and dipole chaff. Hostile radar uses are guarded against via an SPO-15 radar warning receiver. An airtight avionics compartment is behind the cockpit and in front of the forward fuel tank. The newer Su-25TM and Su-25SM models have an upgraded avionics and weapons suite, resulting in improved survivability and combat capability.[15] Operational history Further information: Operational history of the Sukhoi

Shindand Airbase
in western Afghanistan, becoming the first Su-25 unit deployed to that country. Its main task was to conduct air strikes against mountain military positions and structures controlled by the Afghan rebels.[17] Another Soviet Su-25 unit was the 368th Attack Aviation Regiment, which was formed on 12 July 1984, at Zhovtneve in Ukraine.[18] It was soon also moved east to conduct operations over Afghanistan. Over the course of the Soviet war in Afghanistan, Su-25s launched a total of 139 guided missiles of all types against Mujahideen positions. On average, each aircraft performed 360 sorties a year, a total considerably higher than that of any other combat aircraft in Afghanistan. By the end of the war, nearly 50 Su-25s were deployed at Afghan airbases, carrying out a total of 60,000 sorties. Between the first deployment in 1981 and the end of the war in 1989, 21–23 aircraft were lost in combat operations, with up to 9 destroyed on the ground while parked.[17][19] Iran– Iraq

in 1987 and performed approximately 900 combat sorties towards the end of the war, carrying out the bulk of Iraqi air attack missions. During the most intense combat of the war, Iraqi Su-25s performed up to fifteen sorties per day, each. In one recorded incident, an Iraqi Su-25 was shot down by an Iranian, Hawk surface-to-air missile, but the pilot managed to eject. This was the only confirmed, successful Iranian attack against an Iraqi Su-25. After the war, Saddam Hussein

During the Gulf War
Gulf War
of 1991, the air superiority of the coalition forces was so great that the majority of Iraqi Su-25s did not even manage to get airborne. On 25 January 1991, seven Iraqi Air Force Su-25s fled from Iraq
Iraq
and landed in Iran.[20] On the evening of 6 February 1991, two US Air Force F-15C Eagle fighters of the 53rd Tactical Fighter Squadron, operating from Al Kharj Air Base in Saudi Arabia, intercepted a pair of Iraqi MiG-21s and a pair of Su-25s. All four Iraqi aircraft were shot down, with both Su-25s coming down in the desert not far from the Iraqi border with Iran. This was the Iraqi Su-25s' only air combat of the war.[17] Abkhazian War The Georgian government used Su-25s in 1992–93 against Abkhaz separatists during the First Abkhazian War.[21] A Georgian Air Force Su-25 was shot down over Nizhnaya Eshera

air assets, they achieved air supremacy for Russian Forces. On 29 November 1994, attacking all four Chechen military bases, Russian Su-25 from the 368th OShAP destroyed up to 266 Chechen aircraft on the ground, mostly not airworthy.[24] The Air Force's deployed assets performed around 9,000 air sorties, with around 5,300 being strike sorties during the Chechen campaign between 1994 and 1996. The 4th Russian Air Army had 140 Su-17Ms, Su-24s and Su-25s in the war zone supported by an A-50 AWACS aircraft. The employed munitions were generally unguided S-5, S-8, and S-24 rockets, as well as FAB-250 and FAB-500
FAB-500
bombs, while only 2.3% of the strikes used precision-guided Kh-25ML missiles, KAB-500L and KAB-500KR

smart bombs when weather conditions were suitable.[25] Russian forces were not able to properly take advantage of the achieved air supremacy due to obsolete air tactics that focused the Air Force on useless tasks in this type of war such as Combat Air Patrols.[26] The Russian air losses were low since no integrated air defense was fielded by the Chechens.[27] On 4 February 1995, a Russian Su-25 was shot down by ZSU-23-4

Another Su-25 piloted by Lt. Col. Evgeny Derkulsky was damaged by ground fire on the same day, but managed to land at Mozdok air base, where the aircraft was repaired.[24] On 5 May 1995, another Russian Su-25 was downed near Serzhen-Yurt by 12.7 mm fire while on a low-altitude patrol. The pilot, Col. Vladimir Sarabeyev, was killed.[28] On 4 April 1996, another Su-25 fell either to ZU-23-2

Su-25s were extensively used during the Second Chechen War in particular during the first phase when Russian forces were invading the self-proclaimed Chechen Republic of Ichkeria.[31] Up to seven Russian Su-25s were lost,[27] one to hostile fire: on 4 October 1999, a Su-25 was shot down by a MANPADS during a reconnaissance mission over the village of Tolstoy-Yurt killing its pilot. The wings of the aircraft were put on a pedestal in the central square in Grozny.[29][32] Ethiopian-Eritrean War Main article: Ethiopian-Eritrean War Su-25 attack aircraft were used by the Ethiopian Air Force

A Syrian militant said that the pilot ejected safely but killed himself with a grenade to avoid capture.[69][70][71][72] Variants Su-25

Soviet Su-25 in flight

The basic version of the aircraft was produced at Factory 31, at Tbilisi, in the Soviet Republic of Georgia. Between 1978 and 1989, 582 single-seat Su-25s were produced in Georgia, not including aircraft produced under the Su-25K export program. This variant of the aircraft represents the backbone of the Russian Air Force's Su-25 fleet, currently the largest in the world.[7] The aircraft experienced a number of accidents in operational service caused by system failures attributed to salvo firing of weapons. In the wake of these incidents, use of its main armament, the 240 mm S-24 rocket, was prohibited. In its place, the FAB-500
FAB-500
500 kg general-purpose high-explosive bomb became the primary armament.[7] Su-25K The basic Su-25 model was used as the basis for a commercial export variant, known as the Su-25K (Komercheskiy). This model was also built at Factory 31 in Tbilisi, Georgia. The aircraft differed from the Soviet Air Force
Soviet Air Force
version in certain minor details concerning internal equipment. A total of 180 Su-25K aircraft were built between 1984 and 1989.[7] Su-25UB The Su-25UB trainer (Uchebno-Boyevoy) was drawn up in 1977. The first prototype, called "T-8UB-1", was rolled out in July 1985 and its maiden flight was carried out at the Ulan-Ude
Ulan-Ude
factory airfield on 12 August of that year.[7] By the end of 1986, 25 Su-25UBs had been produced at Ulan-Ude
Ulan-Ude
before the twin-seater completed its State trials and officially cleared for service with the Soviet Air Force.[73][clarification needed] It was intended for training and evaluation flights of active-duty pilots, and for training pilot cadets at Soviet Air Force
Soviet Air Force
flying schools. The performance did not differ substantially from that of the single-seater. The navigation, attack, sighting devices and weapons-control systems of the two-seater enabled it to be used for both routine training and weapons-training missions.[74] Su-25UBK

Bulgarian Su-25UBK on take-off

From 1986 to 1989, in parallel with the construction of the main Su-25UB combat training variant, the Ulan-Ude
Ulan-Ude
plant produced the so-called "commercial" Su-25UBK, intended for export to countries that bought the Su-25K, and with similar modifications to that aircraft.[75] Su-25UBM The Su-25UBM is a twin seat variant that can be used as an operational trainer, but also has attack capabilities, and can be used for reconnaissance, target designation and airborne control. Its first flight was on 6 December 2008 and it was certified in December 2010. It will enter operational use with the Russian Air Force
Russian Air Force
later. The variant has a Phazotron

Su-25UTG carrier-based trainer aircraft at Novofedorovka airbase

The Su-25UTG (Uchebno-Trenirovochnyy s Gakom) is a variant of the Su-25UB designed to train pilots in takeoff and landing on a land-based simulated carrier deck, with a sloping ski-jump section and arrester wires. The first one flew in September 1988, and approximately 10 were produced.[77] About half remained in Russian service after 1991; they were used on Russia's sole aircraft carrier, the Admiral Kuznetsov. This small number of aircraft were insufficient to meet the training needs of Russia's carrier air group, so a number of Su-25UBs were converted into Su-25UTGs. These aircraft being distinguished by the alternative designation Su-25UBP (Uchebno-Boyevoy Palubny) —the adjective palubnyy meaning "deck", indicating that these aircraft have a naval function.[78] Approximately 10 of these aircraft are currently operational in the Russian Navy
Russian Navy
as part of the 279th Naval Aviation Regiment.[79] Su-25BM The Su-25BM (Buksirovshchik Misheney) is a target-towing variant of the Su-25 whose development began in 1986. The prototype, designated T-8BM1, successfully flew for the first time on 22 March 1990, at Tbilisi. After completion of the test phase, the aircraft was put into production.[78] The Su-25BM target-tower was designed to provide towed target facilities for training ground forces and naval personnel in ground-to-air or naval surface-to-air missile systems. It is powered by an R-195 engine and equipped with an RSDN-10
RSDN-10
long-range navigation system, an analogue of the Western LORAN
LORAN
system.[78] Su-25T The Su-25T (Tankovy) is a dedicated antitank version, which has been combat-tested with notable success in Chechnya.[15] The design of the aircraft is similar to the Su-25UB. The variant was converted to one-seater, with the rear seat replaced by additional avionics.[80] It has all-weather and night attack capability. In addition to the full arsenal of weapons of the standard Su-25, the Su-25T can employ the KAB-500Kr TV-guided bomb and the semi-active laser-guided Kh-25ML.[15] Its enlarged nosecone houses the Shkval optical TV and aiming system with the Prichal laser rangefinder and target designator. It can also carry Vikhr
Vikhr
laser-guided, tube-launched missiles, which is its main antitank armament. For night operations, the low-light TV Merkuriy pod system can be carried under the fuselage. Three Su-25Ts prototypes were built in 1983–86 and 8 production aircraft were built in 1990.[81] With the introduction of a definitive Russian Air Force Su-25 upgrade programme, in the form of Stroyevoy Modernizirovannyi, the Su-25T programme was officially canceled in 2000.[82] Su-25TM (Su-39)

Russian Su-25TM has been built in small numbers. Carries (from tip to fuselage) R-73, R-77, 8×Vikhr, Kh-29T, Kh-58. White dome of Kopyo radar container is seen below, while two Omul ECM pods lie beside the aircraft.

A second-generation Su-25T, the Su-25TM (also designated Su-39), has been developed with improved navigation and attack systems, and better survivability. While retaining the built-in Shkval of Su-25T, it may carry Kopyo (rus. "Spear") radar in the container under fuselage, which is used for engaging air targets (with RVV-AE/ R-77
R-77
missiles) as well as ships (with Kh-31 and Kh-35 antiship missiles). The Russian Air Force has received 8 aircraft as of 2008.[80] Some of the improved avionics systems designed for T and TM variants have been included in the Su-25SM, an interim upgrade of the operational Russian Air Force Su-25, for improved survivability and combat capability.[15] The Su-25TM, as an all-inclusive upgrade programme has been replaced with the "affordable" Su-25SM programme.[82] Su-25SM

Su-25SM at the Celebration of the 100th anniversary of Russian Air Force

The Su-25SM (Stroyevoy Modernizirovannyi) is an "affordable" upgrade programme for the Su-25, conceived by the Russian Air Force
Russian Air Force
in 2000. The programme stems from the attempted Su-25T and Su-25TM upgrades, which were evaluated and labeled as over-sophisticated and expensive. The SM upgrade incorporates avionics enhancements and airframe refurbishment to extend the Frogfoot's service life by up to 500 flight hours or 5 years.[82] The Su-25SM's all-new PRnK-25SM "Bars" navigation/attack suite is built around the BTsVM-90 digital computer system, originally planned for the Su-25TM upgrade programme. Navigation and attack precision provided by the new suite is three times better of the baseline Su-25 and is reported to be within 15 m (49 ft) using satellite correction and 200 m (660 ft) without it.[82] A new KA1-1-01 Head-Up Display (HUD) was added providing, among other things, double the field of view of the original ASP-17BTs-8 electro-optical sight. Other systems and components incorporated during the upgrade include a Multi-Function Display (MFD), RSBN-85 Short Range Aid to Navigation (SHORAN), ARK-35-1 Automatic Direction Finder (ADF), A-737-01 GPS/GLONASS Receiver, Karat-B-25 Flight Data Recorder (FDR), Berkut-1 Video Recording System (VRS), Banker-2 UHF/VHF communication radio, SO-96 Transponder and a L150 "Pastel" Radar
Radar
Warning Receiver (RWR).[82] The R-95Sh engines have been overhauled and modified with an anti-surge system installed. The system is designed to improve the resistance of the engine to ingested powders and gases during gun and rocket salvo firing.[82] The combination of reconditioned and new equipment, with increased automation and self-test capability has allowed for a reduction of pre- and post-flight maintenance by some 25 to 30%. Overall weight savings are around 300 kg (660 lb).[82] Su-25SM weapon suite has been expanded with the addition of the Vympel R-73 highly agile air-to-air missile (albeit without helmet mounted cuing and only the traditional longitudinal seeker mode) and the S-13T 130 mm rockets (carried in five-round B-13 pods) with blast-fragmentation and armour-piercing warheads. Further, the Kh-25ML and Kh-29L Weapon Employment Profiles have been significantly improved, permitting some complex missile launch scenarios to be executed, such as: firing two consecutive missiles on two different targets in a single attack pass. The GSh-30-2
GSh-30-2
cannon (250-round magazine) has received three new reduced rate-of-fire modes: 750, 375 and 188 Rounds per Minute. The Su-25SM was also given new BD3-25 under-wing pylons.[82] The eventual procurement programme is expected to include between 100 and 130 kits, covering 60 to 70 percent of the Russian Air Force active single-seat fleet, as operated in the early 2000s.[82] On 21 February 2012, Air Force spokesman Col. Vladimir Drik said that Russia will continue to upgrade its Su-25 attack aircraft to Su-25SM version, which has a significantly better survivability and combat effectiveness. The Russian Air Force
Russian Air Force
currently had over 30 Su-25SMs in service and plans to modernize about 80 Su-25s by 2020, Drik said.[83][84] By March 2013, over 60 aircraft are to be upgraded.[84][85] In February 2013, ten new Su-25SMs were delivered to the Air Force southern base,[86][87] where operational training is being conducted.[88] Since early 2014, the Guards Aviation Division Attack Aviation Regiment of the Southern Military District in the Krasnodar region received 16 advanced Su-25SMs.[89] Su-25KM The Su-25KM (Kommercheskiy Modernizirovannyy), nicknamed "Scorpion", is an Su-25 upgrade programme announced in early 2001 by the original manufacturer, Tbilisi
Tbilisi
Aircraft Manufacturing in Georgia, in partnership with Elbit Systems
Elbit Systems
of Israel. The prototype aircraft made its maiden flight on 18 April 2001 at Tbilisi
Tbilisi
in full Georgian Air Force markings.[90] The aircraft uses a standard Su-25 airframe, enhanced with advanced avionics including a glass cockpit, digital map generator, helmet-mounted display, computerised weapons system, complete mission pre-plan capability, and fully redundant backup modes. Performance enhancements include a highly accurate navigation system, pinpoint weapon delivery systems, all-weather and day/night performance, NATO compatibility, state-of-the art safety and survivability features, and advanced onboard debriefing capabilities complying with international requirements.[90] It has the ability to use Mark 82 and Mark 83 laser-guided bombs and air-to-air missiles, the short-range Vympel R-73.[91] Su-28

Su-28 (also designated Su-25UT – Uchebno-Trenirovochnyy) is an advanced basic jet trainer, built on the basis of the Su-25UB as a private initiative by the Sukhoi
Sukhoi
Design Bureau. The Su-28 is a light aircraft designed to replace the Czechoslovak Aero L-39 Albatros. Unlike the basic Su-25UB, it lacks a weapons-control system, built-in cannon, weapons hardpoints, and engine armour.[92] Other

Su-25R (Razvedchik) – a tactical reconnaissance variant designed in 1978, but never built.[93] Su-25U3 (Uchebnyy 3-myestny) – also known as the "Russian Troika", was a three-seat basic trainer aircraft. The project was suspended in 1991 due to lack of funding.[93] Su-25U (Uchebnyy) – a trainer variant of Su-25s produced in Georgia between 1996 and 1998. Three aircraft were built in total, all for the Georgian Air Force.[93] Su-25M1/Su-25UBM1 – Su-25 and Su-25UB exemplars slightly modernized by Ukrainian Air Force, at least nine modernized (eight single-seat and one two-seat). Upgrades include a new navigation system, enhanced survivability, more accurate weapon delivery and other minor changes.[94] Ge-31 is an ongoing Georgian program of Tbilisi

Notable accidents See also: Lists of accidents and incidents involving military aircraft The Su-25 has been involved in the following notable aviation accidents.

An Su-25K of the Air Force of the Democratic Republic of the Congo disappeared in December 2006 during a routine rebasing operation and no wreckage was ever found.[104] Another Congolese Su-25K crashed on 30 June 2007 during an Independence Day display, near the city of Kisangani, killing the pilot. Investigations revealed that the crash was due to an engine failure.[104] An Su-25 of the Russian Air Force
Russian Air Force
exploded in mid-air on 20 March 2008 during a live firing exercise over the Primorsky Krai, 143 km (89 mi) from Vladivostok, killing the pilot. Further investigations revealed that the aircraft was downed by a missile accidentally launched by a wingman. After the accident, all Russian Su-25s were grounded until the investigation was concluded.[115]
