However, this windshield was dropped in favor of

1258-582: Is a variable-sweep wing fighter-bomber developed for the Soviet military. Developed from the Sukhoi Su-7 , the Su-17 was the first variable-sweep wing aircraft to enter Soviet service and featured updated avionics. The aircraft also has variants which were designed to be exported to non-Soviet states such as the Sukhoi Su-22 and the less popular Su-20 . It was produced from 1967–1990. The Su-17/20/22 series had

1332-625: The Council of Ministers . The design of the Su-7IG was modified further, eventually with enough difference to justify the S-32 internal designation. The S-32 first took off on July 1, 1969, with Yevgeny Kukushev at the controls. Serial production started at Yuri Gagarin Aviation Factory (now KnAAPO ) in 1969. The 523rd Aviation Regiment, of the Far East Military Okrug, was the first to receive

As of late 2023, all Russian, Indian, Sri Lankan, Ukrainian, and Kazakh MiG-27s have been retired, bringing the type's service to an end. The MiG-27 shares the basic airframe of the MiG-23, but with a revised nose – nicknamed " Utkonos " (" Platypus ") or " Krokodil Gena " in Russian service, first introduced on the MiG-23B. Dissatisfaction with

1480-528: The Russian Air Force retired its last Su-17M4 along with its fleet of MiG-23/27s in 1998. The Soviets supplied the communist government of Angola with 12 Su-20Ms in 1982 or 1983, which formed the basis of the 15th FS. The squadron suffered a swift loss of at least six aircraft – most in mishaps – by 1985, and three more by 1988, and had only two aircraft left when it was reinforced with batch of 14 Su-22M-4Ks and two Su-22UM-3Ks in 1989–90 (incorporated into

1554-683: The 1990s. Soviet forces used the MiG-27 during the later stages of the Afghanistan conflict in 1987–89, which was the only time the Soviets used this aircraft in action. During the initial stages of the war, MiG-27s were not deployed to support ground troops in combat, as the Sukhoi Su-17s of the Turkestan and Central Asian military districts together with DRAAF Su-7s were considered sufficient to support

1628-755: The 26th Air Regiment, based in Moçâmedes ). From 22 September 1980 to 20 August 1988, during the Iran–Iraq War , Iraq used Su-17 export versions (Su-20 and Su-22) alongside older Su-7s . They were mostly used in ground-attack and close air support roles. Iranian Grumman F-14 Tomcats shot down 21 Su-20/-22s, that have been confirmed by western sources. Eighteen Su-20/-22s were also shot down by Iranian McDonnell Douglas F-4 Phantom IIs . and three by Iranian Northrop F-5s . On 20 October 1980 an Iraqi Su-20 shot down an Iranian F-4E with its 30 mm cannons. Official Iraqi accounts show no loss of Su-20 aircraft throughout

1702-616: The 40th Army's operations against the Afghan Mujahideen . However, in 1988 it was decided to deploy MiG-27s to support the existing forces in theatre. The 134th APIB, formed of three squadrons of MiG-27D/Ms and MiG-23UB trainers, was deployed to Shindand Air Base in October after extensive training in Kazakhstan. The most modern variant, the MiG-27K, was not deployed due to its lack of armour for

1776-575: The 642nd GvAIP, re-equipped with MiG-29 fighters. Additionally, between 1990 and 1994 a single regiment of MiG-27s (the 88th Separate Fighter Bomber Regiment ) served with Soviet Naval Aviation as a way to save the unit from being dissolved under the Treaty on Conventional Armed Forces in Europe . By the collapse of the Soviet Union , a number of MiG-27s remained in service. These would then be inherited by

1850-732: The Air Force. The decision would also allow the Air Force to retain the well-trained ground crews and pilots operating the aircraft. The Poles consider the Su-22 easier to maintain and repair than the other main combat aircraft types currently in Polish service (mainly the MiG-29 and the F-16). They suffer from fewer malfunctions and other problems (high, 70–75% non-error index). It is the only aircraft in Polish inventory equipped for electronic intelligence, warfare, and support of ground systems. The Polish Air Force retained

1924-593: The C-130 had been operating. During the brief 1995 Cenepa War between Peru and Ecuador, two Peruvian Sukhoi Su-22s were lost, on 10 February when two Ecuadorian Air Force Mirage F1 JAs, piloted by Maj. R. Banderas and Capt. C. Uzcátegui, were directed over five targets approaching the disputed Cenepa valley. After making visual contact, the Mirages launched their missiles, however the Ecuadorian Air Force never showed

The crew members, Captain Attia Abdel Salem al Abdali and his copilot, Ali Omar Gaddafi, were ordered to bomb the city in response to the Libyan Civil War . They refused, bailing out of the aircraft. Su-22s were heavily used by Libyan loyalist forces against insurgent forces from mid-February to mid-March 2011, when

2146-473: The HUD videos of the fighters confirming the shootdowns, claiming two Peruvian Su-22As shot down, while a Kfir claimed a further Cessna A-37 Dragonfly . Peru, however, denied that the two Su-22As were shot down by Mirages, stating that one was struck by Ecuadorian anti-aircraft artillery during a low flying ground-attack mission and the second crashed because of an engine fire. The Su-22s flew 45 sorties into

2220-539: The IQAF was moving its aircraft to Iran. On 20 and 22 March 1991, two other Su-22s were downed by USAF F-15s in an attempt to protect Kurdish civilians before the start of Operation Provide Comfort to provide humanitarian aid and the establishment of a no-fly zone north of 36th parallel. Two Libyan Su-22s were shot down in the Gulf of Sidra incident by United States Navy Grumman F-14 Tomcats on 19 August 1981. One Su-22 launched

2294-485: The MiG-23BN led to the further development of the basic airframe to accommodate a stronger undercarriage, simpler intakes and a shorter exhaust nozzle, without radar in favour of a downward-sloping profile for improved pilot visibility, a laser rangefinder and marked-target seeker. Among its test pilots, it was also called " Balkon " ("Balcony") because of the increased frontal view from the cockpit. Additional cockpit armor

Unlike the MiG-23, the MiG-27 did not have widespread use outside Russia, as most countries opted for

4810-450: Was a cheaper variant than the MiG-27K, but much better than the MiG-23B, MiG-23BN, and MiG-27 (MiG-23BM), with the electro-optical and radio-frequency heads above the glove pylons deleted. It was first armed with the GSh-6-23M Gatling gun, but this was later replaced by a new 30 mm GSh-6-30 six-barrel cannon with 260 rounds of ammunition in a fuselage gondola. It also received much-improved electronic countermeasure (ECM) systems, and

4884-401: Was also the first variant armed with a Gryazev-Shipunov GSh-6-30 M Gatling gun . Its NATO reporting name was Flogger-D . NATO reporting name : Flogger-J2 . The MiG-27K was the most advanced Soviet variant, with a laser designator and compatibility with TV-guided electro-optical weapons. It carried the GSh-6-30 cannon. Around 200 were built. NATO reporting name : Flogger-J . This model

4958-408: Was first flown on 28 December 1971 by V. S. Soloviev. The export version was designated Su-20, and was first flown on 15 December 1972 by A. N. Isakov. The Su-17M was manufactured between 1972 and 1975, and entered service in 1973. The Su-20 was exported to Egypt, Poland, and Syria. The Su-17M was fitted with a modified fuselage and wing-sweep mechanism (without driveshafts). The fuel system consisted of

5032-428: Was installed, along with a totally new nav/attack system . Since the MiG-27 was intended to fly most of its missions at low altitude, the MiG-23's variable intake ramps and exhaust nozzles were discarded in favor of a simpler fixed configuration, reducing weight and maintenance requirements. The aircraft also has larger, heavy-duty landing gear to facilitate operation from poorer-quality airfields. In accordance with

5106-417: Was later lost in an accident. Following the S-22I, two pre-production prototypes were constructed, designated S32-1 and the S32-2. The two aircraft mounted updated avionics, and replaced the older AP-28I-2 autopilot with the newer SAU-22 automatic control system. The next series of prototypes were the Su-7-85, with 85 indicating the batch number. The batch of ten aircraft incorporated a redesigned fuselage,

5180-447: Was powered by the AL-21F. Only 24 were produced, due to a lack of engines (the AL-21F was destined for the Sukhoi Su-17/22 and the Su-24 Fencer). It was armed with the GSh-23L cannon, carrying 200 rounds. Derived from the MiG-23B, but powered by the R29B-300 engine. This gave the advantage of making this variant exportable (the AL-21F was a restricted engine at the time, unlike the R29B-300). The R29B-300 also offered commonality with

5254-438: Was powered by the same Lyulka AL-7F-1 engine as the Su-7. It was manufactured between 1969 and 1973, with a total of 224 built. This version used the Lyulka AL-21F-3 engine, and an updated navigation and attack computer. The Su-7BMK's SRD-5M ranging radar was retained. Twin pitot tubes, angle of attack vane, single brake parachute. The variable-position intake centerbody provided maximum speed of Mach 2.1. This version

5328-548: Was put into service, the Sukhoi Design Bureau was ordered to develop a modernization program. The program would be aimed primarily at updating on-board avionics and takeoff/landing characteristics. The concept of variable-geometry wings - something gaining wider attention at that time - was adopted. The program was to be led by Sukhoi's head designer, Nikolay Zyrin. In 1963, the Sukhoi OKB with input from TsAGI created

5402-616: Was rescued after two hours in the water. In 2012, Poland was investigating the replacement of its Su-22s with three squadrons of unmanned aerial vehicles . As of 2014 the Polish Air Force was planning to retain the Su-22s in service. The decision was hoped to have a positive impact on Polish industry, as the WZL nr 2 repair facility in Bydgoszcz would maintain the remaining aircraft under contract to

5476-554: Was the same as the MiG-27M, except the undernose fairing for the infra-red search and track (IRST) sensor had a single window instead of several, like the one on the original MiG-27M. A total of 150 were assembled by India. India refers to this model as the MiG-27M Bahadur , while MiG-27L is the Mikoyan export designation. This was a 1988 indigenous Indian upgrade of its license-assembled MiG-27Ls with French avionics , which provides
