The '''General Electric F404''' and '''F412''' are a family of [[afterburning]] [[turbofan]] engines in the {{convert|10500|-|19000|lbf|kN|abbr=on|lk=on}} class (static thrust). The series is produced by [[GE Aerospace]]. Partners include [[Volvo Aero]], which builds the [[Volvo RM12|RM12]] variant. The F404 was developed into the larger [[General Electric F414|F414]] turbofan, as well as the experimental [[General Electric GE36|GE36]] civil [[propfan]].

==Design and development==

===F404===

GE developed the F404 for the [[F/A-18 Hornet]], shortly after losing the competition for the [[F-15 Eagle]]'s engine to [[Pratt & Whitney]], and losing the [[Lightweight Fighter]] (LWF) competition to the [[Pratt & Whitney F100]] powered [[F-16 Fighting Falcon|YF-16]]. For the F/A-18, GE based the F404 on the [[General Electric YJ101|YJ101]] engine they had developed for the [[Northrop YF-17]], enlarging the bypass ratio from 0.20 to 0.34 to enable higher fuel efficiency. The engine consists of a three-staged fan, seven axial stage compressor arrangement, single stage low and high pressure turbines, an augmentor, and produces maximum thrust of 16,000 lbf (71.2 kN) in the original F404-GE-400 model. The engine was designed with a higher priority on reliability than performance. Cost was the main goal in the design of the engine.<ref>Spick, Mike ed, ''Great Book of Modern Warplanes'', pp. 274–278. MBI, 2000. {{ISBN|0-7603-0893-4}}.</ref>

GE also analyzed "throttle profiles" and found that pilots were changing throttle settings far more often than engineers previously expected, putting undue stress on the engines. GE also sought with the F404 a design that would avoid compressor stalls and other engine failures, and would respond quickly to control inputs; a common complaint of pilots converting from propeller planes to jets was that early turbojets were not responsive to changes in thrust input. GE executives Frederick A. Larson and Paul Setts also set the goal that the new engine would be smaller than the F-4's [[General Electric J79|GE J79]], but provide at least as much thrust, and cost half as much as the P&W F100 engine for the F-16.<ref name="Orr">{{cite book |author=Kelly, Orr |title=Hornet: the inside story of the F/A-18 |location=Novato |publisher=Presidio Press |year=1990 |isbn=0-89141-344-8}}</ref>

Due to a fan designed to smooth airflow before it enters the compressor, the F404 has high resistance to [[compressor stall]]s, even at high angles of attack. It requires less than two shop visits per 1,000 flight hours and averages 6,500 hours between in-flight events. It also demonstrates high responsiveness to control inputs, spooling from idle to full afterburner in 4 seconds. The engine contains an in-flight engine condition monitoring system (IECMS) that monitors for critical malfunctions and keeps track of parts lifetimes.<ref name="Jenkins_p144">Jenkins 2000, p. 144.</ref>

GE developed the [[General Electric F110|F110]] for the Air Force as an alternative to the [[Pratt & Whitney F100]] for use on the F-16 and F-15 based on the [[General Electric F101|F101]] and used F404 technology.<ref>{{Cite web |url=http://www.geae.com/engines/military/f110/spotlight_lockheed.html |title=GEAE: F110 Engine |access-date=2008-02-26 |archive-date=2008-02-25 |archive-url=https://web.archive.org/web/20080225110909/http://www.geae.com/engines/military/f110/spotlight_lockheed.html |url-status=dead }}</ref> The F110 was derived from the F101 via the F101DFE, though some elements of the F404 such as the design of the fan, albeit enlarged, were incorporated, per the F110 page and other sources. GE developed the F404-GE-402 in response to a Swiss requirement for more power in its F/A-18 version; it produces a maximum of 17,700 lbf (78.7 kN) of thrust with afterburner.<ref name="Jenkins_p63-97"/> The new engine version was used on Kuwaiti Hornets, later U.S. C and D Hornets, and subsequent Hornets.<ref name="Jenkins_p63-97">Jenkins 2000, pp. 62–63, 93, 97.</ref> The [[KAI T-50 Golden Eagle]] uses a single General Electric F404-GE-102 turbofan engine with [[Full Authority Digital Engine Control]] (FADEC) system; the engine is similar to the F404-402, but with additional redundancies built in for single-engine operations. The aircraft has a maximum speed of Mach 1.5.

The General Electric F404-GE-103 is the latest derivative of the F404 engine family, developed for use in advanced trainer and light combat aircraft. It was originally developed for the [[Boeing T-7A Red Hawk]], and is also used in the [[Turkish Aerospace]] [[Hürjet]]. The -103 variant includes safety features tailored for single-engine operations and incorporates a Full Authority Digital Electronic Control (FADEC) system derived from the GE F414 engine.<ref name="F404_Family">{{cite web |date=2022-01-01 |title=F404 Family Data Sheet |url=https://www.geaerospace.com/sites/default/files/2022-01/F404%20Family%20Data%20Sheet_UPDATED.pdf |url-status=live |archive-url=https://web.archive.org/web/20250413082214/https://www.geaerospace.com/sites/default/files/2022-01/F404%20Family%20Data%20Sheet_UPDATED.pdf |archive-date=2025-04-13 |access-date=18 June 2025 |publisher=GE Aerospace}}</ref><ref>{{cite web |url=https://www.sto.nato.int/publications/STO%20Meeting%20Proceedings/STO-MP-AVT-374/MP-AVT-374-04P.pdf |title=HÜRJET: A new generation advanced jet trainer aircraft |last=Karaarslan |first=İsmail |date=2023 |website=STO/NATO Science and Technology Organization |access-date=18 June 2025}}{{Dead link|date=July 2025 |fix-attempted=yes |url=}}</ref>

Almost 4,000 F404 engines power the F/A-18 Hornets in service worldwide. The F404 engine family had totaled over 12 million flight hours by 2010.<ref>[http://www.geae.com/aboutgeae/presscenter/military/military_20100719.html "Proven Experience, Program Upgrades Spark GE F110 and F404/414 Popularity"]. {{webarchive|url=https://web.archive.org/web/20100929062201/http://geae.com/aboutgeae/presscenter/military/military_20100719.html |date=2010-09-29 }}.

=== F404-GE-IN20 === For the [[HAL Tejas]], GE developed an uprated '''F404-IN20''', which is the highest thrust variant in F404 family, and which produces a maximum of {{Convert|19000|lbf|kN|abbr=on|order=flip}} of thrust with afterburner.<ref>{{cite web |title=F404 |url=https://www.geaviation.com/sites/default/files/datasheet-F404-Family.pdf |website=GE Aviation |publisher=General Electric |access-date=19 January 2022}}</ref><ref name=":0" /> It incorporates latest hot section materials and technologies as well as a [[FADEC]] system for reliable power and performance.<ref name=":1">{{Cite web |title=Hindustan Aeronautics Ltd.

However, General Electric had closed down the production line of F404-IN20 engines without further prospects of orders from India and the first engine was yet to be delivered as of October 2024 leading to the subsequent delivery delays of [[HAL Tejas Mk1A]] to the [[Indian Air Force]].
