The Beriev A-50 (NATO reporting name: Mainstay) is a Soviet-origin airborne early warning and control (AEW&C) aircraft that is based on the Ilyushin Il-76 transport plane. Developed to replace the Tupolev Tu-126 "Moss", the A-50 first flew in 1978. Its existence was revealed to the Western Bloc in 1978 by Adolf Tolkachev. It entered service in 1985, with about 42 produced by 1992 when the breakup of the Soviet Union ended production.
Design and development
A-50
The mission personnel of the 15-man crew derive data from the large Liana surveillance radar with its antenna in an over-fuselage rotodome, which has a diameter of 9 m
The A-50 can control up to ten fighter aircraft for either air-to-air intercept or air-to-ground attack missions. The A-50 can fly for four hours with a range of 1000 km from its base, at a maximum takeoff weight of 190 MT. The aircraft can be refuelled by Il-78 tankers.
The "Vega-M" radar is designed by MNIIP, Moscow, and produced by NPO Vega. The "Vega-M" can track up to 150 targets simultaneously within 230 km. Large targets, like surface ships, can be tracked at a distance of 400 km.
A-50U
Development work on a modernised version, the A-50U, began in 2003; state tests started on 10 September 2008, using a Russian Air Force A-50 "37 Red" as a prototype. It replaces analogue avionics with a new digital avionics suite, made by NPO Vega, that speeds data processing and improves signal tracking and target detection. Crew rest, toilet and galley facilities are also included in the upgrade.
After completing the joint state tests, Beriev delivered the first A-50U to the Russian Air Force. The aircraft, "47 Red", RF-92957, was handed over at Beriev's facility in Taganrog on 31 October 2011. It was accepted by an aircrew serving with the 2457th Aviation Base for Combat Operation of Airborne Early Warning Aircraft (Aviabaza Boevogo Primeneniya Samolyotov Dal'nego Radiolokatsionnogo Obnaruzheniya) at Ivanovo Severny, the only base using the A-50 operationally, which operates 16 aircraft.
The A-50U upgrade forms the basis of the concept for Beriev A-100 AEW&C. Its configuration will be similar, but with a new Vega Premier active electronically scanned array radar.
It was announced by Rostec that production of the A-50U would restart in 2024. However, it is likely that production resumption will be delayed for a few years.
A-50EI
The A-50EI is the designation of the export designation for the Indian Air Force. The AWACS variant based on the Il-76TD platform is equipped with Aviadvigatel PS-90A-76 engines, Vega-supplied data link and Israeli EL/W-2090 radar.
Operational history
In peacetime
The aircraft entered service with the 67th Independent Aviation Squadron, Long-Range Airborne Surveillance (67 OAE DRLO) (в/ч 32457) in 1984 at Šiauliai in the Lithuanian SSR. The unit was redesignated the 144th Independent Regiment DRLO, (в/ч 89449) and later moved to Pechora Kamenka (often referred to as "Berezovka") in 1998.
There was a detachment of two A-50s and one Il-76 as part of the 192nd Guards Kerch Red Banner Military Transport Aviation Regiment (в/ч 26212), Ukurey Airfield Chita Oblast in Russia from 1985 to 1995. It was formed at the Ulan-Ude (Vostochny) airfield in 1985, and flew to Ukurei in 1988. It was disbanded in 1995 and aircraft transferred to the 144th Independent Regiment. The 18th Independent Aviation Detachment DRLO (two A-50s and 1 Il-76) was established at the Vitebsk-Severny airfield from 1985. In 1993, the detachment was disestablished.
Two aircraft "operated round-the-clock over [the] Black Sea during Operations Desert Shield and Desert Storm of the Gulf War (1990–1991), monitoring United States Air Force operations from Turkey and keeping a watch for "stray" cruise missiles."
Syrian Civil War
In late December 2015, the A-50 started operations over Syria, flying from Russia, to support Russian military intervention in the Syrian Civil War.
Russo-Ukrainian War
In December 2018, the A-50 was deployed to Crimea.
On 26 February 2023, during the Russian invasion of Ukraine, the Association of Security Forces of Belarus (BYPOL), a partisan group, reported that it had conducted a drone attack and damaged a Russian A-50 at the Machulishchy air base near Minsk, Belarus. The attacked base also hosts MiG-31 fighters used to attack Ukraine. However, satellite imagery of the Machulishchy air base from 28 February showed no significant damage to the sole A-50 located there. The drone operators posted a video of a practice run of the alleged A-50U bombing on YouTube on 2 March 2023, which shows the drone flying into Machulishchy unopposed, then landing on the A-50's rotodome. On 3 March 2023, the drone operators posted a second video showing a drone landing on the domed area on top of the fuselage just forward of the wings followed by a loss of video signal claimed to be due to the actual explosion.
On 17 November 2023, the British Defence Ministry said that it believed it "likely" that Russian forces were updating their A-50 early warning aircraft in anticipation of the West supplying Ukraine with modern fighter jets such as the F-16. The aircraft may also be integrated with ground-based S-400 missile systems.
Ukrainian forces claimed to have shot down an A-50 over the Sea of Azov on 14 January 2024 while it was on duty in the Kyrylivka area. The A-50 reportedly disappeared from radar and stopped responding to requests from tactical aviation. Later several Western and Ukrainian sources reported that the pilot of a Su-30 aircraft of the Russian Air Force detected the fire and crash of an unidentified aircraft in the area, presumably the A-50. Forbes journalist David Axe cited one analyst who said that the Ukrainian Air Force first disabled Russian radars across Crimea, causing the Russians to re-establish radar coverage there by moving their A-50 north to near Berdyansk, thus within range of a Ukrainian SAM battery which shot it down. This was stated to leave the Russian air force with just two serviceable A-50s. , Russian "war correspondents" have confirmed that the A-50 was indeed shot down. But, we still don't have official information from the Kremlin that it was shot down. Open source analysts later identified that the aircraft lost was A-50U "37 red" of the 610th Center for Combat Use and Retraining of Military Transport Aviation Flight Personnel (610th CBP i PLS), based at Ivanovo Severny. Col. Rosanna Clemente, Assistant Chief of Staff at the 10th US Army Air and Missile Defense Command, later confirmed that this A-50 had been shot down by a Ukrainian-operated Patriot air defense system.
Ukrainian official sources said that on 23 February 2024 a second A-50U aircraft had been shot down, over the Sea of Azov in Krasnodar Krai, at 18:44 Ukraine local time, Ukrainian language. by a long-range Soviet-era S-200 missile system. According to Ukrainian sources, 10 Russians were killed on the plane, including five majors. The aircraft was later identified as A-50U "42 red" of the 610th CBP i PLS. Kyrylo Budanov, head of Ukraine's Defence Intelligence, said that as of 25 February 2024 Russia had only six operational A-50s. The BBC stated at this time that Russia had originally had six A-50s operational, with two destroyed in 2024 leaving it with only four.
The Taganrog Beriev Aviation Scientific and Technical Complex where the A-50s are repaired was reported to have suffered damage on the night of March 8/9, 2024, possibly from a Ukrainian drone strike.
On 1 June 2025, the Ukrainian SBU claimed to have damaged an A-50 at the Ivanovo airbase, using drones as part of Operation Spider's Web. Extended footage confirmed to journalists that two A-50s were damaged in the operation. It is unclear if the A-50s damaged were in a usable state with at least one missing engines and both having worn radomes.
