The '''Lockheed Martin/Boeing F-22 Raptor''' is an American [[Twinjet|twin-engine]], [[Night fighter|all-weather]], [[supersonic]] [[Stealth aircraft|stealth]] [[fighter aircraft]]. As a product of the [[United States Air Force]]'s [[Advanced Tactical Fighter]] (ATF) program, the aircraft was designed as an [[air superiority fighter]], but also incorporates [[attack aircraft|ground attack]], [[electronic-warfare aircraft|electronic warfare]], and [[signals intelligence]] capabilities. The prime contractor, [[Lockheed Martin Aeronautics|Lockheed Martin]], built most of the F-22 airframe and weapons systems and conducted final assembly, while program partner [[Boeing Defense, Space & Security|Boeing]] provided the wings, [[aft]] fuselage, [[avionics]] integration, and training systems.

First flown in 1997, the F-22 descended from the [[Lockheed YF-22]] and was variously designated '''F-22''' and '''F/A-22''' before it formally entered service in December 2005 as the '''F-22A'''. Although the U.S. Air Force (USAF) had originally planned to buy a total of 750 ATFs to replace its [[McDonnell Douglas F-15 Eagle|F-15 Eagle]]s, it later scaled down to 381, and the program was ultimately cut to 195 aircraft – 187 of them operational models – in 2009 due to political opposition from high costs, a perceived lack of air-to-air threats at the time of production, and the development of the more affordable and versatile [[Lockheed Martin F-35 Lightning II|F-35]].{{refn|Referring to statements made by the Secretary of Defense Robert Gates: "The secretary once again highlighted his ambitious next-year request for the more-versatile F-35s."<ref>{{cite web |last=Baron |first=Kevin |url=http://www.stripes.com/news/gates-outlines-air-force-priorities-and-expectations-1.94837 |title=Gates outlines Air Force priorities and expectations |work=Stars and Stripes |date=16 September 2009 |access-date=30 October 2013 |archive-url=https://web.archive.org/web/20131031171947/http://www.stripes.com/news/gates-outlines-air-force-priorities-and-expectations-1.94837 |archive-date=31 October 2013 |url-status=live}}</ref>|group=N}} The last aircraft was delivered in 2012.

The F-22 is a critical component of the USAF's high-end tactical airpower. While it had a protracted development and initial operational difficulties, the aircraft became the service's leading counter-air platform against peer adversaries. Although designed for air superiority operations, the F-22 has also performed strike and electronic surveillance, including missions in the [[Middle East]] against the [[Islamic State]] and [[Al-Assad family|Assad]]-aligned forces. The F-22 is expected to remain a cornerstone of the USAF's fighter fleet until its succession by the [[Boeing F-47]].<ref>{{Cite web |last=Trimble |first=Steve |date=March 21, 2025 |title=Boeing Wins U.S. Air Force's NGAD F-47 Fighter Contract |url=https://aviationweek.com/defense/aircraft-propulsion/boeing-wins-us-air-forces-ngad-f-47-fighter-contract |access-date=March 21, 2025 |website=[[Aviation Week & Space Technology]]}}</ref><ref>{{Cite web |last=Epstein |first=Jake |date=March 21, 2025 |title=First US sixth-gen fighter jet will be the F-47, Trump says, and Boeing, not Lockheed, is going to build it |url=https://www.businessinsider.com/boeing-wins-air-force-next-generation-air-dominance-fighter-contract-2025-3 |access-date=March 21, 2025 |website=Business Insider |language=en-US}}</ref>

===Origins===
{{main|Advanced Tactical Fighter|Lockheed YF-22}}
[[File:Advanced Tactical Fighter Systems Project Office Patch.jpg|thumb|ATF SPO Patch, 1990]]

The F-22 originated from the [[Advanced Tactical Fighter]] (ATF) program that the U.S. Air Force (USAF) initiated in 1981 to replace the [[McDonnell Douglas F-15 Eagle|F-15 Eagle]] and [[General Dynamics F-16 Fighting Falcon|F-16 Fighting Falcon]]. Intelligence reports indicated that their effectiveness would be eroded by emerging worldwide threats emanating from the [[Soviet Union]], including new developments in surface-to-air missile systems for integrated air defense networks, the introduction of the [[Beriev A-50]] "Mainstay" airborne warning and control system (AWACS), and the proliferation of the [[Sukhoi Su-27]] "Flanker" and [[Mikoyan MiG-29]] "Fulcrum" class of fighter aircraft.<ref>Jenkins, Dennis R. ''Lockheed Secret Projects: Inside the Skunk Works.'' St. Paul, Minnesota: MBI Publishing Company, 2001. {{ISBN|0-7603-0914-0}}. pp.&nbsp;70.</ref> Code-named "''Senior Sky''", the ATF would become an air superiority fighter program influenced by these threats; in the potential scenario of a Soviet and [[Warsaw Pact]] invasion in [[Central Europe]], the ATF was envisaged to support the [[AirLand Battle|air-land battle]] by spearheading [[offensive counter air|offensive]] and defensive counter-air operations (OCA/DCA) in this highly contested environment that would then enable following echelons of NATO strike and attack aircraft to perform [[air interdiction]] against ground formations; to do so, the ATF would make an ambitious leap in capability and survivability by taking advantage of the new technologies in fighter design on the horizon, including [[composite material]]s, lightweight [[alloy]]s, advanced flight control systems and avionics, more powerful propulsion systems for supersonic cruise (or [[supercruise]]) around Mach 1.5, and stealth technology for low observability.<ref>{{cite web |url=https://www.nationalmuseum.af.mil/Visit/Museum-Exhibits/Fact-Sheets/Display/Article/196040/lockheed-martin-f-22a-raptor/ |title=Lockheed Martin F-22A Raptor |work=National Museum of the U.S. Air Force}}</ref><ref>Pace 1999, pp. 3–4.</ref><ref>Aronstein and Hirschberg 1998, pp. 51-54, 72.</ref>

The USAF published an ATF [[request for information]] (RFI) to the aerospace industry in May 1981, and following a period of concept and specification development, the ATF System Program Office (SPO) issued the demonstration and validation (Dem/Val) [[request for proposal]]s (RFP) in September 1985, with requirements placing strong emphasis on stealth, supersonic cruise and maneuver. The RFP saw some alterations after its initial release, including more stringent signature reduction requirements in December 1985 and the addition of the requirement for flying technology demonstrator prototypes in May 1986.{{refn|The greatly increased stealth requirements arose from the SPO's discussions with Lockheed and Northrop, the two companies with prior stealth experience from the "''Senior Trend''"/[[Lockheed F-117 Nighthawk|F-117]] and "''Senior Ice''"/[[Northrop B-2 Spirit|B-2]] respectively.<ref>Aronstein and Hirschberg 1998, pp. 56–57.</ref>|group=N}}<ref>Aronstein and Hirschberg 1998, pp. 82–89.</ref> Owing to the immense investments required to develop the advanced technologies, teaming among companies was encouraged. Of the seven bidding companies,{{refn|The seven bidding companies for Dem/Val were Lockheed, Northrop, General Dynamics, Boeing, McDonnell Douglas, [[Grumman]], and [[Rockwell International|North American Rockwell]].<ref>Miller 2005, pp. 14, 19.</ref>|group=N}} [[Lockheed Corporation|Lockheed]] and [[Northrop Corporation|Northrop]] were selected on 31 October 1986.{{refn|Lockheed's design had considerable variations throughout concept exploration, ranging from [[Lockheed SR-71 Blackbird|SR-71]]/[[Lockheed YF-12|YF-12]]-like, to faceted designs similar to the F-117, to a curved surface design with an arrowhead-like planform as the company became able to design stealthy shapes with curved surfaces.<ref name="f22_evolution_p1">{{cite web |last=Hehs |first=Eric |url=https://www.codeonemagazine.com/article.html?item_id=179 |title=F-22 Raptor Design Evolution, Part 1 |work=Lockheed Martin |date=1998 |access-date=13 March 2023 |archive-date=16 January 2022 |archive-url=https://web.archive.org/web/20220116193649/https://www.codeonemagazine.com/article.html?item_id=179 |url-status=live}}</ref>|group=N}} Lockheed, through its [[Skunk Works]] division at [[Burbank, California]], teamed with [[Boeing]] and [[General Dynamics]] while Northrop teamed with [[McDonnell Douglas]]. These two contractor teams undertook a 50-month Dem/Val phase, culminating in the flight test of two technology demonstrator prototypes, the [[Lockheed YF-22]] and [[Northrop YF-23]]; while they represented competing designs, the prototypes were meant for demonstrating concept viability and risk mitigation rather than a competitive flyoff.{{refn|The contractor teams were to give the SPO "sealed envelope" flight performance predictions against which their prototypes would be evaluated, rather than against each other.<ref>Aronstein and Hirschberg 1998, p. 137.</ref>|group=N}} Concurrently, [[Pratt & Whitney]] and [[General Electric]] competed for the ATF engines.<ref>Jenkins and Landis 2008, pp.&nbsp;233–234.</ref><ref>Williams 2002, pp.&nbsp;5–6.</ref>

[[File:F-22 design evolution 595 to 645 200x592.png|thumb|upright=0.66|Evolution of the F-22 design from 1987, with the bottom being the production configuration.]]
Dem/Val was focused on [[system engineering]], technology development plans, and risk reduction over point aircraft designs; in fact, after down-select, the Lockheed team completely redesigned the airframe configuration in summer 1987 due to weight analysis, with notable changes including the [[Wing configuration#Wing planform|wing planform]] from swept trapezoidal to diamond-like delta and a reduction in forebody planform area.<ref>Aronstein and Hirschberg 1998, p. 119.</ref><ref>Mullin 2019.</ref> The team extensively used analytical and empirical methods including [[computational fluid dynamics]] and [[computer-aided design]], [[wind tunnel]] testing (18,000 hours for Dem/Val), and [[radar cross-section]] (RCS) calculations and pole testing. Avionics were tested in ground prototypes and flying laboratories.<ref>Aronstein and Hirschberg 1998, pp. 104–125.</ref> During Dem/Val, the SPO used [[trade study|trade studies]] from both teams to review the ATF system specifications and adjust or delete requirements that were significant weight and cost drivers while having marginal value. The short takeoff and landing ([[STOL]]) requirement was relaxed to delete [[thrust reversal|thrust-reversers]], saving substantial weight. [[Side looking airborne radar|Side looking radar]]s and the dedicated [[infrared search and track]] (IRST) system were eventually removed as well, although space and cooling provisions were retained to allow for their later addition. The [[ejection seat]] was downgraded from a fresh design to the existing [[ACES II]]. Despite efforts by both teams to rein in weight, the takeoff gross weight estimates grew from {{convert|50000|to|60000|lb|kg|sigfig=3|abbr=on}}, resulting in engine thrust requirement increasing from {{convert|30000|to|35000|lbf|kN|0|abbr=on}} class.<ref>Aronstein and Hirschberg 1998, pp. 105–108.</ref>

Each team built two prototype air vehicles for Dem/Val, one for each engine option. The YF-22 had its maiden flight on 29 September 1990 and, in testing, successfully demonstrated supercruise, high angle-of-attack maneuvers, and the firing of air-to-air missiles from internal weapons bays. After the flight test of the demonstrator prototypes at [[Edwards Air Force Base]], the teams submitted the results and their full-scale development design proposals – or Preferred System Concept – in December 1990; on 23 April 1991, the [[United States Secretary of the Air Force|Secretary of the USAF]], [[Donald Rice]], announced the Lockheed team and Pratt & Whitney as the winners of the ATF and engine competitions.<ref>Jenkins and Landis 2008, p.&nbsp;234.</ref> Both designs met or exceeded all performance requirements; the YF-23 was considered stealthier and faster, but the YF-22, with its thrust vectoring nozzles, was more maneuverable as well as less expensive and risky, having flown considerably more test sorties and hours than its counterpart.<ref name="Goodall_p110">Goodall 1992, p.&nbsp;110.</ref><ref>Aronstein and Hirschberg 1998, pp. 159–160.</ref> The press also speculated that the Lockheed team's design was more adaptable to the Navy Advanced Tactical Fighter (NATF) for replacing the [[Grumman F-14 Tomcat|F-14 Tomcat]], but by fiscal year (FY) 1992, the [[United States Navy|U.S. Navy]] had abandoned NATF due to cost.<ref name=Miller_p76>Miller 2005, p. 76.</ref>

===Full-scale development===
The program formally moved to full-scale development, or [[Manufacturing readiness level#Definitions|Engineering & Manufacturing Development]] (EMD), in August 1991. The production F-22 design (internally designated Configuration 645) had also evolved to have notable differences from the YF-22, which was immature due to being frozen relatively soon after the complete redesign in the summer of 1987.{{refn|The YF-22 outer lines were frozen to allow construction to begin in 1988, resulting in the shaping being rather unrefined, especially compared to the YF-23.<ref name="f22_evolution_p2"/>|group=N}} While the overall layout was similar, the external geometry saw significant alterations; the wing's [[leading edge]] sweep angle was decreased from 48° to 42°, while the vertical stabilizers were shifted rearward and decreased in area by 20%.<ref name="NASA">{{cite web |url=http://oea.larc.nasa.gov/PAIS/Partners/F_22.html |archive-url=https://web.archive.org/web/20040118030146/http://oea.larc.nasa.gov/PAIS/Partners/F_22.html |archive-date=18 January 2004 |title=F-22 Partners |work=NASA |access-date=25 July 2009}}</ref> The radome shape was changed for better radar performance, the wingtips were clipped for antennas, and the dedicated airbrake was eliminated.

Aside from advances in air vehicle and propulsion technology, the F-22's avionics were unprecedented in complexity and scale for a combat aircraft, with the integration of multiple sensors systems and antennas, including electronic warfare, communication/navigation/identification (CNI), and software of 1.7&nbsp;million [[Source lines of code|lines of code]] written in [[Ada (programming language)|Ada]]. Avionics often became the pacing factor of the whole program. In light of rapidly advancing computing and semiconductor technology, the avionics was to employ the [[United States Department of Defense|Department of Defense]]'s (DoD) ''[[PAVE|PAVE PILLAR]]'' systems architecture and [[Very High Speed Integrated Circuit Program|Very High Speed Integrated Circuit]] (VHSIC) program technology; the computing and processing requirements were equivalent to multiple contemporary [[Cray#Cray Research Inc. and Cray Computer Corporation: 1972–1996|Cray]] supercomputers to achieve [[sensor fusion]].<ref>Aronstein and Hirschberg 1998, p. 170.</ref><ref name="B3.0SW">[http://www.fas.org/man/dod-101/sys/ac/docs/man-ac-f22-010105.htm "F-22 aircraft No. 4005 completes successful first flight"]. {{Webarchive|url=https://web.archive.org/web/20170629121402/https://fas.org/man/dod-101/sys/ac/docs/man-ac-f22-010105.htm |date=29 June 2017}}.

The roughly equal division of work amongst the team largely carried through from Dem/Val to EMD, with prime contractor Lockheed responsible for the forward fuselage and control surfaces, General Dynamics for the center fuselage, and Boeing for aft fuselage and wings. Lockheed [[General Dynamics#Divestitures|acquired General Dynamics]]' fighter portfolio at [[Fort Worth, Texas]] in 1993 and thus had the majority of the airframe manufacturing, and merged with [[Martin Marietta]] in 1995 to form [[Lockheed Martin]]. While Lockheed primarily performed Dem/Val work at its Skunk Works sites in Burbank and Palmdale, [[California]], it shifted its program office and EMD work from Burbank to [[Marietta, Georgia]], where it performed final assembly; [[Boeing Defense, Space & Security|Boeing]] manufactured airframe components, performed avionics integration and developed the training systems in [[Seattle, Washington]]. The EMD contract originally ordered seven single-seat F-22As and two twin-seat F-22Bs, although the latter was canceled in 1996 to reduce development costs and the orders were converted to single seaters.<ref>Aronstein and Hirschberg 1998, p. 118.</ref> The first F-22A, an EMD aircraft with [[United States military aircraft serial numbers|tail number]] 91-4001, was unveiled at [[United States Air Force Plant 6|Air Force Plant 6]] in [[Dobbins Air Reserve Base]] in Marietta on 9 April 1997 where it was officially named "Raptor".{{refn|The YF-22 was originally given the unofficial name "Lightning II", from the World War II [[Lockheed P-38 Lightning]] fighter which persisted until the mid-1990s, when the USAF officially named the F-22 "Raptor".

The F-22 flight test program consisted of flight sciences, developmental test (DT), and initial operational test and evaluation (IOT&E) by the [[411th Flight Test Squadron]] (FLTS) at Edwards AFB, California, as well as follow-on OT&E and development of tactics and operational employment by the [[422nd Test and Evaluation Squadron]] (TES) at [[Nellis Air Force Base|Nellis AFB]], [[Nevada]]. Nine EMD jets assigned to the 411th FLTS would participate in the test program under the Combined Test Force (CTF) at Edwards. The first two aircraft conducted envelope expansion testing, such as flying qualities, air vehicle performance, propulsion, and stores separation. The third aircraft, the first to have production-level internal structure, tested flight loads, flutter, and stores separation, while two non-flying F-22s were built for testing static loads and fatigue.

[[File:F-22 CRIIS Edwards.png|thumb|left|An EMD F-22 of the 411th FLTS flies over Edwards AFB, California, in 2018.]]
Because the F-22 had been designed to defeat contemporary and projected Soviet fighters, the end of the [[Cold War (1985-1991)|Cold War]] and the [[dissolution of the Soviet Union]] in 1991 had major impacts on program funding; the DoD reduced its urgency for new weapon systems and the following years would see successive reductions in its budget. This resulted in the F-22's EMD being rescheduled and lengthened multiple times. Furthermore, the aircraft's sophistication and numerous technological innovations required extensive testing, which exacerbated the cost overruns and delays, especially from mission avionics. Some capabilities were also deferred to post-service upgrades, reducing the upfront cost but increasing total program cost.<ref>{{cite news |last=Sweetman |first=Bill |url=http://aviationweek.com/awin/rivals-target-jsf |title=Rivals Target JSF |archive-url=https://web.archive.org/web/20160819135759/http://aviationweek.com/awin/rivals-target-jsf |archive-date=19 August 2016 |work=Aviation Week |publisher=McGraw Hill |date=30 November 2010 |access-date=31 August 2011}}</ref><ref>{{cite report |last1=Younossi |first1=Obaid |last2=Stem |first2=David E. |last3=Lorell |first3=Mark A. |last4=Lussier |first4=Frances M. |url=http://www.rand.org/pubs/monographs/MG276.html |title=Lessons Learned from the F/A–22 and F/A–18E/F Development Programs |archive-url=https://web.archive.org/web/20110425192042/http://www.rand.org/pubs/monographs/MG276.html |archive-date=25 April 2011 |publisher=Rand Corporation |year=2005 |access-date=27 August 2011}}</ref> The program transitioned to full-rate production in March 2005 and completed EMD that December, after which the test force had flown 3,496 sorties for over 7,600 flight hours.<ref name=f22milestones/> As the F-22 was designed for upgrades throughout its lifecycle, the 411th FLTS and 422nd TES continued the DT/OT&E and tactics development of these upgrades.<ref name="3.2A_test"/> Derivatives such as the [[Lockheed Martin X-44 MANTA|X-44]] thrust vectoring research aircraft and the [[Lockheed Martin FB-22|FB-22]] medium-range regional bomber were proposed in the late 1990s and early 2000s, although these were eventually abandoned.

===Production and procurement===
The USAF originally envisioned ordering 750 ATFs at a total program cost of $44.3&nbsp;billion and procurement cost of $26.2&nbsp;billion in FY 1985 dollars, with production beginning in 1994 and service entry in the mid-to-late 1990s. The 1990 Major Aircraft Review (MAR) led by [[United States Secretary of Defense|Secretary of Defense]] [[Dick Cheney]] reduced this to 648 aircraft beginning in 1996 and service entry in the early-to-mid 2000s. After the end of the Cold War, this was further curtailed to 442 in the 1993 Bottom-Up Review while the USAF eventually set its requirement to 381 to support its [[Air Expeditionary Force]] structure with the last deliveries in 2013. Throughout development and production, the program was continually scrutinized for its costs and less expensive alternatives such as modernized F-15 or F-16 variants were being proposed, even though the USAF considered the F-22 to provide the greatest capability increase against peer adversaries for the investment.<ref>Aronstein and Hirschberg 1998, pp. 246–256.</ref> However, funding instability had reduced the total to 339 by 1997 and production was nearly halted by [[United States Congress|Congress]] in 1999.{{refn|group=N|Another reason other than funding issues, the F-22’s superior combat capability, has been attributed to cuts to F-22 purchases.

The long gap since the end of production meant hiring new workers, sourcing replacement vendors, and finding new plant space, contributing to the high start-up costs and lead times.

The F-22's shape combines stealth and aerodynamic performance.

The shoulder-mounted wings are smoothly blended into the fuselage with four [[empennage]] surfaces and [[leading edge extension|leading edge root extensions]] running to the caret inlets' upper edges, where the forebody chines also meet. Flight control surfaces include [[Leading-edge slat|leading-edge flaps]], [[flaperon]]s, [[aileron]]s, [[rudder]]s on the canted [[vertical stabilizer]]s, and all-moving horizontal tails ([[stabilator]]s); for [[Air brake (aeronautics)|air braking]], the ailerons deflect up, flaperons down, and rudders outwards to increase drag.<ref>Miller 2005, pp. 79-91.</ref><ref name="f22_flight_test_update"/> Owing to the focus on supersonic performance, [[area rule]] is applied extensively to the airplane's shape and nearly all of the fuselage volume lies ahead of the wing's trailing edge to reduce drag at supersonic speeds, with the stabilators pivoting from tail booms extending aft of the engine nozzles.<ref>Sweetman 1998, pp. 34-36</ref> Weapons are carried internally in the fuselage for stealth.

The F-22's [[thrust-to-weight ratio]] at typical combat weight is nearly at unity in maximum military power and 1.25 in full [[afterburner]]. The fixed shoulder-mounted [[intake ramp|caret inlets]] are offset from the forward fuselage to divert the turbulent [[boundary layer]] and generate oblique shocks with the upper inboard corners to ensure good total pressure recovery and efficient supersonic flow compression.<ref>{{cite book |first1=Jeffrey W. |last1=Hamstra |first2=Brent N. |last2=McCallum |url=https://onlinelibrary.wiley.com/doi/10.1002/9780470686652.eae490 |title=Tactical Aircraft Aerodynamic Integration |doi=10.1002/9780470686652.eae490 |isbn=9780470754405 |date=15 September 2010 |access-date=19 October 2021 |archive-date=19 October 2021 |archive-url=https://web.archive.org/web/20211019070031/https://onlinelibrary.wiley.com/doi/10.1002/9780470686652.eae490 |url-status=live}}</ref> Maximum speed without external stores is approximately [[Mach (speed)|Mach]] 1.8 in supercruise at military/intermediate power and greater than Mach 2 with afterburners.{{refn|This capability was demonstrated in 2005 when General [[John P.

The effectiveness of the stealth characteristics is difficult to gauge. The RCS value is a restrictive measurement of the aircraft's frontal or side area from the perspective of a static radar. When an aircraft maneuvers it exposes a completely different set of angles and surface area, potentially increasing radar observability. Furthermore, the F-22's stealth contouring and radar-absorbent materials are chiefly effective against high-frequency radars, usually found on other aircraft. The effects of [[Rayleigh scattering]] and resonance mean that [[low-frequency radar]]s such as [[weather radar]]s and [[early-warning radar]]s are more likely to detect the F-22 due to its physical size. These are also conspicuous, susceptible to [[Clutter (radar)|clutter]], and have low precision.<ref>Ralston, J; Heagy, J; et al.

The F-22 underwent extensive testing before its service introduction. While the first production aircraft was delivered to Edwards AFB in October 2002 for IOT&E and the first jet for the 422nd TES at Nellis AFB arrived in January 2003, IOT&E was continually pushed back from its planned start in mid-2003, with mission avionics stability being particularly challenging.{{refn|In 2002–2003, the F-22's software reliability was highly inadequate, needing to initiate an avionics system restart (which took minutes to cycle) every 1.9 hours despite the requirement for "mean-time between instability events" being over 20 hours.

To increase deployment responsiveness and reduce logistical footprint in a peer or near-peer conflict, the USAF developed a deployment concept called Rapid Raptor which involves two to four F-22s and one [[Boeing C-17 Globemaster III|C-17]] for logistical support, first proposed in 2008 by two F-22 pilots. The goal was for the type to be able to set up and engage in combat within 24 hours in smaller and more austere environments that would enable more dispersed and survivable disposition of forces.

On 25 March 2009, an EMD F-22 crashed {{convert|35|mi|km}} northeast of Edwards AFB during a [[test flight]], resulting in the death of Lockheed Martin test pilot [[David P. Cooley]]. An [[Air Force Materiel Command]] investigation found that Cooley momentarily lost consciousness during a high-G maneuver, or [[g-LOC]], then ejected when he found himself too low to recover. Cooley was killed during ejection by blunt-force [[Blunt trauma|trauma]] from windblast due to the aircraft's speed. The investigation found no design issues.<ref>{{cite news |title=F-22 Crash Linked To G-Forces |newspaper=The Washington Post |date=5 August 2009 |page=2}}</ref><ref>{{cite report |url=http://www.airforcemag.com/SiteCollectionDocuments/Reports/2009/July%202009/Day31/F-22_AIB_073109.pdf |title=USAF AIB Report on 25 March 2009 F-22A mishap |archive-url=https://web.archive.org/web/20190331150934/http://www.airforcemag.com/SiteCollectionDocuments/Reports/2009/July%25202009/Day31/F-22_AIB_073109.pdf |archive-date=31 March 2019 |access-date=31 May 2014}}</ref>
