The Medium Multi-Role Combat Aircraft (MMRCA) competition, also known as the MRCA tender, was a competition to supply 126 multi-role combat aircraft to the Indian Air Force (IAF).
 The Defence Ministry has allocated ₹ crore () for the purchase of these aircraft, making it India's single largest defence deal.
 The MRCA tender was floated with the idea of filling the gap between its future Light Combat Aircraft and its in-service Sukhoi Su-30MKI air superiority fighter.
A multirole combat aircraft (MRCA) is a combat aircraft intended to perform different roles in combat.
 A multirole fighter is a multirole combat aircraft which is, at the same time, also a fighter aircraft; in other words, an aircraft whose various roles include, among others, the role of air-to-air combat.
Fourth-generation jet fighter is a general classification of jet fighters in service from approximately 1980 to the present and represent design concepts of the 1970s.
 Fourth-generation designs are heavily influenced by lessons learned from the previous generation of combat aircraft.
 Long-range air-to-air missiles, originally thought to make dogfighting obsolete, proved less influential than expected, precipitating a renewed emphasis on maneuverability.
 Meanwhile, the growing costs of military aircraft in general and the demonstrated success of aircraft such as the F-4 Phantom II gave rise to the popularity of multirole combat aircraft in parallel with the advances marking the so-called fourth generation.
In current military parlance, a strike fighter is a multirole combat aircraft designed to operate primarily as an attack aircraft, while also incorporating certain performance characteristics of a fighter.
 As a category, it is distinct from fighter-bombers.
 It is closely related to the concept of interdictor aircraft, but it puts more emphasis on air-to-air combat capabilities as a multirole combat aircraft.
 Examples of contemporary American strike fighters are the McDonnell Douglas F-15E Strike Eagle, Boeing F/A-18E/F Super Hornet, and Lockheed Martin F-35 Lightning II.
Military aircraft insignia are insignia applied to military aircraft to identify the nation or branch of military service to which the aircraft belongs.
 Many insignia are in the form of a circular roundel or modified roundel; other shapes such as stars, crosses, squares or triangles are also used.
The Tupolev Tu-160 "Beliy Lebed" (or White Swan, Russian: Туполев Ту-160 Белый лебедь , NATO reporting name: Blackjack) is a supersonic, variable-sweep wing heavy strategic bomber designed by the Tupolev Design Bureau in the Soviet Union.
 It is the largest and heaviest Mach 2+ supersonic aircraft ever built and second only to the comparable XB-70 Valkyrie in overall length.
 It is the largest and heaviest combat aircraft, the fastest bomber currently in use, and is the largest and heaviest variable-sweep wing airplane ever flown.
Mil Mi-X1 is a high-speed helicopter being proposed by Mil of Russia.
 The aircraft belongs to the same program as its competitor Kamov's Ka-92 intended to create a new generation of middle-class helicopters cruising at about 500 km/h (312 mph).
 Its preliminary design and early specifications were unveiled at HeliRussia 2009 exhibition near Moscow.
NATO reporting names are code names for military equipment of Russia, China, and, historically, the former Eastern Bloc (Soviet Union and other nations of the Warsaw Pact).
 They provide unambiguous and easily understood English words in a uniform manner in place of the original designations, which either may have been unknown to the Western world at the time or easily confused codes.
 For example, the Russian bomber jet Tupolev Tu-160 is simply called Blackjack.
The Junkers Ju 88 was a German World War II "Luftwaffe" twin-engined multirole combat aircraft.
 Junkers Flugzeug- und Motorenwerke (JFM) designed the plane in the mid-1930s as a so-called "Schnellbomber" (fast bomber) that would be too fast for fighters of its era to intercept.
 It suffered from a number of technical problems during its development and early operational periods but became one of the most versatile combat aircraft of the war.
 Like a number of other "Luftwaffe" bombers, it served as a bomber, dive bomber, night fighter, torpedo bomber, reconnaissance aircraft, heavy fighter and at the end of the war, as a flying bomb.
The Aeronautical Development Agency (ADA) of India's Ministry of Defence was established at Bangalore, in 1984 to oversee the development of the nation's Light Combat Aircraft (LCA) programme.
 Currently, the organisation is involved in design and development of multiple versions of LCA, HAL AMCA and UCAV.
 Dr. Girish S. Deodhare is the Programme Director, Combat Aircraft and Director, ADA.
 He's one of the students of Dr. Vidyasagar, who is considered to be the pioneers of advanced technology of his times.
