The Shenyang J-11 (Chinese: 歼-11), with NATO reporting name Flanker B+, is a single-seat, twin-engine jet fighter, whose airframe is based on the Soviet-designed Sukhoi Su-27 air superiority fighter.
 It is currently manufactured by the Shenyang Aircraft Corporation.
 The People's Liberation Army Air Force (PLAAF) of China (PRC) is the sole operator of the aircraft.
The Shenyang J-31 (or "FC-31 fifth Generation Multi-Purpose Medium Fighter") also known as the "Gyrfalcon" (鹘鹰), or "Falcon Hawk" by some military enthusiasts, is a twin-engine, mid-size fifth-generation jet fighter currently under development by Shenyang Aircraft Corporation.
 The fighter has also been referred to as the "F-60" or "J-21 Snowy Owl" (雪鸮) in some media reports.
 Its official name is Shenyang FC-31; J-xx nomenclatures in the Chinese military are reserved to programs launched and financed by the army, while this plane was developed by a state-owned company.
The Supermarine Attacker was a British single-seat naval jet fighter built by Supermarine for the Royal Navy's Fleet Air Arm (FAA).
 The type has the distinction of being the first jet fighter to enter operational service with the FAA.
 Like most other first-generation jet fighters, it had a short service life due to the rapid development of increasingly advanced aircraft during the 1950s and 1960s.
A fifth-generation jet fighter is a jet fighter classification used around the world that encompasses the most advanced jet fighter generation.
 The exact characteristics of fifth-generation jet fighters are controversial and vague, with Lockheed Martin defining them as having all-aspect stealth even when armed, low probability of intercept radar (LPIR), high-performance airframes, advanced avionics features, and highly integrated computer systems capable of networking with other elements within the battlespace for situation awareness.
The Sukhoi Su-25 "Grach" (Russian: Грач ("rook"); NATO reporting name: Frogfoot) 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 Mikoyan MiG-29 (Russian: Микоян МиГ-29 ; NATO reporting name: Fulcrum) is a twin-engine jet fighter aircraft designed in the Soviet Union.
 Developed by the Mikoyan design bureau as an air superiority fighter during the 1970s, the MiG-29, along with the larger Sukhoi Su-27, was developed to counter new American fighters such as the McDonnell Douglas F-15 Eagle, and the General Dynamics F-16 Fighting Falcon.
 The MiG-29 entered service with the Soviet Air Force in 1982.
China Aviation Industry Corporation I (AVIC I) was a Chinese consortium of aircraft manufacturers.
 The consortium was created on 1 July 1999 by splitting the state-owned consortium China Aviation Industry Corporation (AVIC) into AVIC I and AVIC II.
 AVIC I was historically focused on large planes such as bombers (Xian H-6, Xian JH-7), medium commercial planes (ARJ21), or fighter planes (J-7, J-8, J-10, J-11 and JF-17), while AVIC II was focused on smaller planes and helicopters.
 On 28 October 2008, the companies officially consolidated back into one organization to more efficiently manage resources and avoid redundant projects.
The Lavochkin La-150 (also known as the "Izdeliye" 150 – Aircraft or Article 150, USAF/DOD designation Type 3), was designed by the Lavochkin design bureau (OKB) in response to a 1945 order to build a single-seat jet fighter using a single German turbojet.
 By this time both the Americans and British, as well as the Germans, had already flown jet fighters and the single Soviet jet engine under development (the Lyulka TR-1) was not yet ready for production.
 The design was completed quickly, but the construction of the five flying prototypes was protracted by the factory's inexperience in building metal aircraft.
 The aircraft made its first flight in September 1946, but proved to require extensive modifications to meet the Soviet Air Forces' requirements.
 These took so long to make and test that the aircraft was essentially obsolete by the time that they were completed.
 Even one variant with a much more powerful engine was inferior to other aircraft that the OKB had under development and all work was terminated in 1947.
The McDonnell XF-88 Voodoo was a long-range, twin-engine jet fighter aircraft with swept wings designed for the United States Air Force.
 Although it never entered service, its design was adapted for the subsequent supersonic F-101 Voodoo.
The Sukhoi Su-57 (Russian: Сухой Су-57 ) is the designation intended for a stealth, single-seat, twin-engine jet multirole fighter aircraft designed for air superiority and attack operations.
 The aircraft is the product of the PAK FA (Russian: ПАК ФА , Russian: Перспективный авиационный комплекс фронтовой авиации , "Perspektivny Aviatsionny Kompleks Frontovoy Aviatsii", literally "Prospective Airborne Complex of Frontline Aviation"), a fifth-generation fighter programme of the Russian Air Force.
 Sukhoi's internal name for the aircraft is T-50.
 The Su-57 will be the first aircraft in Russian military service to use stealth technology.
 The fighter is planned to have supercruise, stealth, supermaneuverability and advanced avionics to overcome the prior generation fighter aircraft as well as ground and maritime defences.
