4th Generation Multi-Role Fighters (1/72)

Aerospaceweb
In 2004 the website Aerospaceweb noted that classification by generations, "appears to have first appeared in Russia during the mid-1990s when officials were planning a competitor to the American Joint Strike Fighter" and proposed a classification :[7]

4. 1970 to 1990, emphasizing maneuverability rather than speed : F-14, F-15, F-16, F/A-18, AV-8B, MiG-29, MiG-31, Su-27, Su-33, Yak-141, Panavia Tornado, Mirage 2000, Viggen, Mitsubishi F-2, AIDC Ching-Kuo, Chengdu J-10
4.5. 1990 to 2000, enhanced capabilities, advanced avionics, limited Stealth technology characteristics : F/A-18E/F, Su-30, Su-34, Su-35, Mig-35, Eurofighter Typhoon, Saab Gripen, Dassault Rafale

Air Force Magazine
In 2009, Air Force Magazine also define fighter generations and proposed a sixth :[10]

4. Pulse-doppler radar; high maneuverability; look-down/shoot-down missiles : F-15, F-16, Mirage 2000, MiG-29.
4+. High agility; sensor fusion; reduced radar signature : Eurofighter Typhoon, Su-30, F/A-18E/F, Rafale
4++. Active electronically scanned arrays; continued reduced signatures or “active” (waveform canceling) stealth technology, supercruise : Su-35, proposed F-15SE

Jim Winchester
Jim Winchester, in a book published in 2011 by The Rosen Publishing Group, proposed the following definitions:[11][citation not found]

4. 1975–2005. relaxed stability by fly-by-wire, digital computers, Active electronically scanned array, Infra-red search and track : F-14, F-15, F-16, F/A-18
4+, 4++. 1986- high capacity data-link

Air Power Development Centre Bulletin classification
The Royal Australian Air Force Air Power Development Centre Bulletin proposed a classification in 2012:

4. 1970 to late 1980s. head-up displays, fly-by-wire, Swing-role fighters : MiG-29, Su-27, F/A-18, F-15, F-16, Mirage 2000
4.5. late 1980s into the 90s. (half generation from a reduction in military spending) stealth technology, Radar-absorbent materials, thrust vectoring, Active Electronically Scanned Array radar, Network Warfare, multirole missions : F/A-18E/F, F-15SE, Eurofighter Typhoon, Saab Gripen, Dassault Rafale
