Below is list of Ukrainian aircraft losses during the Ukrainian crisis, including the 2014 pro-Russian unrest in Ukraine, the 2014 Crimean crisis, and the war in Donbass.
A prolonged crisis in Ukraine began on 21 November 2013 when the then-president of Ukraine Viktor Yanukovych suspended preparations for the implementation of an association agreement with the European Union. The decision sparked mass protests from proponents of the agreement. The protests, in turn, precipitated a revolution that led to Yanukovych's ousting in February 2014. After the ousting, unrest enveloped in some largely Russophone eastern and southern regions of Ukraine, from where Yanukovych had drawn most of his support. Subsequently, an ensuing political crisis developed after Russia invaded said regions and annexed the then-autonomous Ukrainian region of Crimea in March 2014. As Russia's invasion emboldened the Russophone Ukrainians already in upheaval, the unrest in the Donetsk and Luhansk oblasts devolved into a subnational war against the post-revolutionary Ukrainian government. As that conflict progressed, the Russophone Ukrainian opposition turned into a pro-Russian insurgency, often supported and assisted by the Russian military and its special forces.
From the end of February 2014, demonstrations by pro-Russian and anti-government groups took place in major cities across the eastern and southern regions of Ukraine, in the aftermath of the Euromaidan movement and the 2014 Ukrainian revolution. During the first stage of the unrest, Crimea was annexed by the Russian Federation after a Russian military intervention, and an internationally criticized Crimean referendum. Protests in Donetsk and Luhansk regions (oblasts) escalated into an armed pro-Russian separatist insurgency. From late 2014, cities outside of the Donbass combat zone, such as Kharkiv, Odessa, Kiev and Mariupol, were struck by bombings that targeted pro-Ukrainian unity organizations. To maintain control over southeastern territories Ukraine's government started "antiterrorist operation" (ATO) sending armed forces to suppress separatists. Armed conflict between Ukraine's government forces and pro-Russian rebels is known as War in Donbass.
The War in Donbass is an armed conflict in the Donbass region of Ukraine. From the beginning of March 2014, protests by pro-Russian and anti-government groups took place in the Donetsk and Luhansk oblasts of Ukraine, commonly collectively called the "Donbass", in the aftermath of the 2014 Ukrainian revolution and the Euromaidan movement. These demonstrations, which followed the annexation of Crimea by the Russian Federation, and which were part of a wider group of concurrent pro-Russian protests across southern and eastern Ukraine, escalated into an armed conflict between the separatist forces of the self-declared Donetsk and Luhansk People's Republics, and the Ukrainian government. In the Donetsk People's Republic, from May 2014 until a change of the top leadership in August 2014, some of the top leaders were Russian citizens. According to the Ukrainian government, at the height of the conflict in mid-2014, Russian paramilitaries were reported to make up between 15% to 80% of the combatants.
The Kyiv Post newspaper reported on 22 August 2014, that since the beginning of the aerial operations in the East, 18 Ukrainian Armed Force aircraft were lost, with 16 shot down or destroyed on the ground and 2 crashed for other reasons. Those lost due to hostile fire included: 10 helicopters (five Mi-8s and five Mi-24s), seven combat planes (one Su-24, four Su-25 and two MiG-29) and three transport planes (a An-26, a An-30 and an Il-76).
The Mil Mi-24 is a large helicopter gunship, attack helicopter and low-capacity troop transport with room for eight passengers. It is produced by Mil Moscow Helicopter Plant and has been operated since 1972 by the Soviet Air Force and its successors, along with more than 30 other nations.
The Siege of Sloviansk was an operation by the Armed Forces of Ukraine to recapture the city of Sloviansk in Donetsk Oblast from pro-Russian insurgents who had seized it on 12 April 2014. The city was taken back on 5 July 2014 after shelling from artillery and heavy fighting. The fighting in Sloviansk marked the first major military engagement between pro-Russian separatists and Ukrainian government forces, in the first runoff of battles of 2014.
The Ministry of Internal Affairs of Ukraine executes state policy for the protection of rights and liberties of citizens, investigates unlawful acts against the interest of society and state, fights crime, provides civil order, ensures civil security, traffic safety, and protects the security and protection of important individuals. It is a centralised agency headed by a Minister of Internal Affairs. The ministry closely operates with the office of General Prosecutor of Ukraine. It oversees the National Police of Ukraine and the National Guard of Ukraine (gendarmerie).
The Sukhoi Su-27 is a twin-engine supermaneuverable fighter aircraft designed by Sukhoi. It was intended as a direct competitor for the large United States fourth-generation fighters such as the Grumman F-14 Tomcat and F-15 Eagle, with 3,530-kilometre (1,910 nmi) range, heavy aircraft ordnance, sophisticated avionics and high maneuverability. The Su-27 was designed for air superiority missions, and subsequent variants are able to perform almost all aerial warfare operations. It was designed with the Mikoyan MiG-29 as its complement.
The Sukhoi Su-25 Grach is a single-seat, twin-engine jet aircraft developed in the 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.
The Syrian Air Force, officially the Syrian Arab Air Force, is the air force branch of the Syrian Armed Forces. It is variously abbreviated in English to SAF, SAAF, or SyAAF. It was established in 1948. Land-based air defense systems are grouped under the Syrian Air Defense Force, which split from both the Air Force and the Army.
The Sukhoi Su-24 is a supersonic, all-weather attack aircraft developed in the Soviet Union. The aircraft has a variable-sweep wing, twin-engines and a side-by-side seating arrangement for its crew of two. It was the first of the USSR's aircraft to carry an integrated digital navigation/attack system. It remains in service with the Russian Air Force, Syrian Air Force, Ukrainian Air Force, Azerbaijan Air Force and various air forces to which it was exported.
The Sukhoi Su-30 is a twin-engine, two-seat supermaneuverable fighter aircraft developed by Russia's Sukhoi Aviation Corporation. It is a multirole fighter for all-weather, air-to-air and air-to-surface deep interdiction missions.
The Sukhoi Su-33 is an all-weather carrier-based twin-engine air superiority fighter designed by Sukhoi and manufactured by Komsomolsk-on-Amur Aircraft Production Association, derived from the Su-27 and initially known as the Su-27K. Compared with the Su-27, the Su-33 has a strengthened undercarriage and structure, folding wings and stabilators, all for carrier operations. The Su-33 has canards and its wings are larger than the Su-27 for increased lift. The Su-33 has upgraded engines and a twin nose wheel, and is air refuelable.
The Sukhoi Su-17 is a Soviet variable-sweep wing fighter-bomber developed from the Sukhoi Su-7. It enjoyed a long career in Soviet, later Russian, service and was widely exported to Eastern Bloc, Arab air forces, Angola and Peru as the Su-20 and Su-22. It is the first variable-sweep wing of Russian/Soviet origin.
The Ukrainian Air Force is a part of the Armed Forces of Ukraine. Ukrainian Air Force headquarters is located in the city of Vinnytsia. When the Soviet Union dissolved in 1991, a large number of aircraft were left on Ukrainian territory. Ever since, the Ukrainian air force has been downsizing and upgrading its forces. In spite of these efforts, the main inventory of the air force consists of Soviet-made aircraft. Currently 36,300 personnel and 144 aircraft are in service in the Ukrainian air force and air defense forces but approximately only eighty aircraft are airworthy. All ICBMs and strategic bombers have been taken out of service.
The Vympel R-73 is a short-range air-to-air missile developed by Vympel NPO that entered service in 1984.
The Sukhoi Su-34 is a Russian twin-engine, twin-seat, all-weather supersonic medium-range fighter-bomber/strike aircraft. It first flew in 1990 and entered service in 2014 with the Russian Air Force.
The Vympel R-27 missile is a medium-to-long-range air-to-air missile developed by the Soviet Union. It remains in service with the Russian Air Force and air forces of the Commonwealth of Independent States.
The Sukhoi Su-30MKI is a twinjet multirole air superiority fighter developed by Russia's Sukhoi and built under licence by India's Hindustan Aeronautics Limited (HAL) for the Indian Air Force (IAF). A variant of the Sukhoi Su-30, it is a heavy, all-weather, long-range fighter.
The Libyan Air Force is the branch of the Libyan military responsible for aerial warfare. In 2010, before the Libyan Civil War, the Libyan Air Force personnel strength was estimated at 18,000, with an inventory of 374 combat capable aircraft operating from 13 military airbases in Libya. Since the 2011 civil war and the ongoing conflict, multiple factions fighting in Libya are in possession of military aircraft. As of 2019 the Libyan Air Force is nominally under the control of the internationally recognised Government of National Accord in Tripoli, though the rival Libyan National Army of Marshal Khalifa Haftar also has a significant air force.
A Turkish Air Force F-16 fighter jet shot down a Russian Sukhoi Su-24M attack aircraft near the Syria–Turkey border on 24 November 2015. According to Turkey, the aircraft—whose nationality was unknown at the time—was fired upon while in Turkish airspace because it violated the border up to a depth of 2.19 kilometres for about 17 seconds after being warned to change its heading 10 times over a period of five minutes before entering the airspace. The Russia Defence Ministry denied the aircraft ever left Syrian airspace, counter-claiming that their satellite data showed that the Sukhoi was about 1,000 metres (1,100 yd) inside Syrian airspace when it was shot down. The U.S. State Department said that the U.S. independently confirmed that the aircraft's flight path violated Turkish territory, and that the Turks gave multiple warnings to the pilot, to which they received no response and released audio recordings of the warnings they had broadcast. Turkish President Recep Tayyip Erdogan pointed out that Turkey had the right to defend its airspace. Russian president Vladimir Putin said that the U.S. knew the flight path of the Russian jet and should have informed Turkey; two U.S. officials said that Russia did not inform the U.S. military of its jet's flight plan.
The 831st Brigade of Tactical Aviation is a formation of the Ukrainian Air Force, composed primarily of Sukhoi Su-27 aircraft, that is based at Mirgorod.
