Aero L-39 Albatros
The Aero L-39 Albatros is a Czechoslovak jet trainer family built by Aero Vodochody, with armed L-39ZO and L-39ZA variants adapted for light attack and weapons training. In the Nagorno-Karabakh Conflict archive it is included conservatively because Armenia fielded L-39 trainers in its 2020 operational air fleet, while available open sources do not verify specific L-39 combat sorties in that war.

Su-22 fighter-bomberVariable-sweep-wing fighter-bomber / ground-attack aircraftThe Su-22 is the export member of Sukhoi's Su-17 Fitter family, a Soviet variable-sweep fighter-bomber built for low-level strike, ground attack, and battlefield interdiction. In the Nagorno-Karabakh archive it represents Azerbaijan's earlier post-Soviet fixed-wing strike fleet, with direct sourcing for a Su-22 loss in 1994 rather than for 2020 combat employment.
AH-64 Apache attack helicopterTwin-engine attack helicopterThe AH-64 Apache is a U.S. twin-engine attack helicopter built for armed reconnaissance, close combat, and precision attack missions with a 30 mm chain gun, rockets, and Hellfire missiles. In the United States-Iran Conflict, official Operation Epic Fury material identified Apaches among U.S. assets, and DVIDS imagery documented AH-64E aircraft from the 82nd Airborne Division operating with rockets and Hellfire missiles in the CENTCOM area.
AH-64A Peten attack helicopterAttack helicopterThe AH-64A Peten is the Israeli Air Force's Apache attack helicopter, a twin-seat strike platform built around the Apache airframe and used for close support and precision attacks. During the Israel-Hamas War, 190 Squadron Peten crews were part of the October 7 response missions, showing the older AH-64A remained in active combat use.
Su-17Variable-sweep wing fighter-bomber / ground-attack aircraftThe Su-17 Fitter is a Soviet variable-sweep wing fighter-bomber developed from the Su-7 and exported as the Su-20 and Su-22. Built for low-level strike and bombing missions with rockets, bombs, missiles, gun pods, and cannon armament, the family remained visible in later conflicts through operators such as Syria.
Su-34Twin-seat fighter-bomber / strike aircraftThe Su-34 Fullback is a Russian twin-seat fighter-bomber derived from the Su-27 family and built for long-range strike, interdiction, and reconnaissance missions. In the Russia-Ukraine War, Russian forces have relied on Su-34s as key launch aircraft for stand-off glide bombs, allowing heavy ordnance delivery while trying to remain outside many Ukrainian short-range air-defense envelopes.
Su-57Fifth-generation multirole fighter aircraftThe Su-57, NATO reporting name Felon, is Russia's Sukhoi-designed fifth-generation multirole fighter, built for air-to-air combat and standoff strike missions with low-observable shaping, integrated avionics, and internal weapons carriage. In the Russia-Ukraine War it has appeared as a scarce Russian Aerospace Forces asset used cautiously, with documented Ukrainian reporting of a June 2024 strike against an Su-57 at Akhtubinsk airfield rather than routine overflight of defended Ukrainian airspace.Sources
