F-22 Raptor: The World's First 5th Generation Stealth Fighter

Lockheed Martin / Boeing · USAF Air Superiority Fighter · First Flight 1997 · IOC 2005

The F-22 Raptor is a single-seat, twin-engine, all-weather stealth tactical fighter aircraft developed for the United States Air Force. As the world's first operational 5th generation fighter, the F-22 combines stealth technology, supercruise capability, thrust vectoring, and advanced integrated avionics to achieve unprecedented air dominance. Designed primarily as an air superiority fighter, the F-22 Raptor also possesses ground attack, electronic warfare, and signals intelligence capabilities.

The Raptor entered service in December 2005 and remains the benchmark against which all modern fighter aircraft are measured. With a radar cross-section smaller than a marble, the ability to cruise at supersonic speeds without afterburner, and sensor fusion that gives the pilot unmatched situational awareness, the F22 Raptor is widely regarded as the most capable air superiority fighter in the world.

Development History: The ATF Program

The origins of the F-22 Raptor trace back to 1981, when the United States Air Force issued a requirement for an Advanced Tactical Fighter (ATF) to replace the F-15 Eagle as America's primary air superiority fighter. The ATF program sought a fighter that could counter emerging Soviet threats — including the Su-27 Flanker and the next generation of Soviet aircraft — while surviving in an environment saturated with advanced surface-to-air missiles.

The USAF defined four key requirements for the ATF: stealth, supercruise (sustained supersonic flight without afterburner), advanced avionics with sensor fusion, and superior agility. These characteristics would come to define what the world now calls a 5th generation fighter.

YF-22 vs YF-23: The Fly-Off

In October 1986, the Air Force selected two competing teams for the demonstration/validation phase:

  • Lockheed / Boeing / General Dynamics — YF-22 (two prototypes built)
  • Northrop / McDonnell Douglas — YF-23 "Black Widow II" (two prototypes built)

The YF-23 was widely considered the more stealthy and faster of the two designs, featuring a diamond-shaped wing planform and ruddervators instead of conventional tail surfaces. The YF-22, while perhaps marginally less stealthy, demonstrated superior agility — particularly at high angles of attack — thanks to its thrust-vectoring nozzles.

On 23 April 1991, Secretary of the Air Force Donald Rice announced that the YF-22 had won the ATF competition. The decision was influenced by the YF-22's demonstrated maneuverability, Lockheed's strong management track record with the F-117 program, and the lower perceived risk of the design. The Pratt & Whitney YF119 engine was selected over the General Electric YF120.

The first production F-22A flew on 7 September 1997. The aircraft underwent extensive testing throughout the early 2000s before achieving Initial Operational Capability (IOC) with the 27th Fighter Squadron at Langley Air Force Base on 15 December 2005.

Stealth Design & Low Observability

The F-22's stealth capabilities are central to its combat effectiveness. The aircraft was designed from the outset to have an extremely low radar cross-section (RCS) across a wide range of frequencies, making it exceptionally difficult to detect, track, and engage with radar-guided weapons.

Key stealth features of the F22 stealth fighter include:

  • Aligned edges — The aircraft's leading and trailing edges are designed with a small number of consistent sweep angles, causing radar energy to be reflected in narrow, predictable directions away from the emitting radar
  • Internal weapons bays — All primary armament is carried internally, eliminating the radar reflections caused by external pylons and missiles
  • Radar-absorbent materials (RAM) — Specialized coatings and structural materials absorb radar energy rather than reflecting it
  • Serrated edges — Access panels, engine inlets, and exhaust nozzles feature saw-tooth edges that scatter radar returns
  • Curved inlet ducts — The S-shaped engine intakes prevent radar energy from reaching the highly reflective compressor fan blades
  • Reduced infrared signature — The flat, wide exhaust nozzles and airframe design help dissipate heat and reduce the aircraft's IR signature

The F-22's RCS is estimated to be approximately 0.0001–0.0015 m² from the frontal aspect — roughly equivalent to a steel marble. This gives the Raptor an enormous advantage in beyond-visual-range (BVR) combat, allowing it to detect and engage enemy aircraft long before they are aware of its presence.

Avionics & Sensor Fusion

The F-22's avionics suite represents a generational leap in fighter aircraft electronics. The centerpiece is the AN/APG-77 active electronically scanned array (AESA) radar, which uses approximately 2,000 transmit/receive modules to provide:

  • Long-range air-to-air detection and tracking of multiple targets simultaneously
  • Low probability of intercept (LPI) operation — the radar can search for targets while making it extremely difficult for enemy radar warning receivers to detect its emissions
  • Electronic warfare and electronic attack capabilities
  • High-resolution synthetic aperture radar (SAR) for ground mapping

The F-22 also carries the AN/ALR-94 electronic warfare suite, one of the most capable passive sensor systems ever fitted to a fighter aircraft. This system can detect, identify, and geolocate enemy radar emissions at ranges exceeding 460 km (250 nmi), allowing the pilot to build a comprehensive picture of the threat environment without emitting any detectable signals.

What makes the F-22's avionics truly revolutionary is sensor fusion — the automated integration of data from the radar, electronic warfare suite, communication links, and other sensors into a single, coherent tactical picture. Rather than forcing the pilot to mentally correlate information from multiple displays, the F-22's computers process all sensor data and present the pilot with a unified situational awareness display. This dramatically reduces pilot workload and allows faster, more accurate decision-making in combat.

Supercruise & Thrust Vectoring

The F-22 is powered by two Pratt & Whitney F119-PW-100 turbofan engines, each producing approximately 156 kN (35,000 lbf) of thrust with afterburner. These are the most powerful fighter engines ever installed in a production aircraft.

The F119 engines enable supercruise — the ability to sustain supersonic flight at Mach 1.82 without using fuel-hungry afterburners. This capability provides enormous tactical advantages:

  • Extended range at supersonic speed — The F-22 can cover more distance at high speed without the massive fuel penalty of afterburner use
  • Greater weapons engagement envelope — Missiles launched at supersonic speed carry greater kinetic energy and have longer effective range
  • Reduced infrared signature — Without afterburner, the engine exhaust is significantly cooler and harder to detect
  • Tactical flexibility — The ability to rapidly transit between engagements at supersonic speed

The F-22's top speed exceeds Mach 2.25 (approximately 2,414 km/h or 1,500 mph) with afterburner. The aircraft's two-dimensional thrust-vectoring nozzles can deflect ±20 degrees in the pitch axis, providing exceptional agility at all speeds, including controlled flight at extremely high angles of attack where conventional fighters would stall.

Armament

The F-22 carries its weapons internally to preserve its stealth profile. The aircraft features three internal weapons bays: a large main bay on the ventral fuselage and two smaller side bays.

Air-to-Air Configuration

  • 6 × AIM-120 AMRAAM — Medium-range, active radar-homing, beyond-visual-range missiles carried in the main weapons bay
  • 2 × AIM-9M/X Sidewinder — Short-range, infrared-homing missiles carried in the side weapons bays
  • 1 × M61A2 Vulcan — 20 mm rotary cannon with 480 rounds, mounted internally in the right wing root

Air-to-Ground Configuration

  • 2 × AIM-120 AMRAAM — Retained for self-defense
  • 2 × AIM-9M/X Sidewinder — Retained for self-defense
  • 2 × GBU-32 JDAM — 1,000 lb GPS-guided bombs in the main weapons bay
  • 1 × M61A2 Vulcan — 20 mm cannon

Extended Loadout (Non-Stealth)

When stealth is not required, the F-22 can carry weapons on four underwing hardpoints, increasing its total payload capacity. This configuration sacrifices the aircraft's low-observable characteristics but is suitable for permissive environments or ferry flights.

The internal weapons bay doors are designed to open and close in less than one second, minimizing the time the aircraft's RCS is increased during weapons release. A sophisticated trapeze launch system pushes missiles clear of the weapons bay before their motors ignite.

Operational History & Deployments

The F-22 achieved Initial Operational Capability with the 27th Fighter Squadron, 1st Fighter Wing at Langley AFB, Virginia, on 15 December 2005. Since then, the Raptor has been deployed across the globe:

  • 2007 — First overseas deployment to Kadena Air Base, Okinawa, Japan, demonstrating Pacific theater reach
  • 2009 — First deployment to Al Dhafra Air Base, UAE, for operations in the Middle East theater
  • 2011 — Operation Odyssey Dawn (Libya) — F-22s provided electronic warfare support and SEAD (Suppression of Enemy Air Defenses) during the opening stages of the campaign against Libyan air defenses. This marked the Raptor's first combat deployment
  • 2014 — Operation Inherent Resolve (Syria/Iraq) — F-22s conducted their first air-to-ground strikes using GBU-32 JDAMs against ISIS targets in Syria on 22 September 2014. The Raptor's stealth allowed it to operate freely over Syria's contested airspace
  • 2015–present — Continued operations over Syria and Iraq, plus regular deployments to Europe and the Pacific to deter Russian and Chinese aggression
  • 2023 — An F-22 from the 1st Fighter Wing shot down a Chinese surveillance balloon over the Atlantic Ocean off South Carolina using an AIM-9X Sidewinder, marking the type's first air-to-air kill

The F-22 is stationed at several USAF bases, including Joint Base Elmendorf-Richardson (Alaska), Joint Base Langley-Eustis (Virginia), Joint Base Pearl Harbor-Hickam (Hawaii), Tyndall AFB (Florida), and Eglin AFB (Florida). Alaska-based Raptors regularly intercept Russian Tu-95 Bear bombers approaching North American airspace.

Why Only 187? The F-22 Production Decision

The F-22 was originally planned for a production run of 750 aircraft. This number was gradually reduced over time: to 648 in 1990, to 442 in 1994, to 339 in 2003, to 183 in 2004, and finally to 187 production aircraft when the program was capped in 2009.

Several factors drove the reduction:

  • Enormous unit cost — At approximately $150 million per aircraft (flyaway cost), and with total program costs exceeding $66 billion, the F-22 was extraordinarily expensive. Defense Secretary Robert Gates argued the money was better spent on more versatile platforms
  • End of the Cold War — The collapse of the Soviet Union in 1991 eliminated the primary threat the F-22 was designed to counter. With no peer adversary fielding comparable aircraft, the urgency for large numbers of air superiority fighters diminished
  • Shift to counterinsurgency — The wars in Iraq and Afghanistan focused attention on ground support and counterinsurgency operations where the F-22's capabilities were considered excessive
  • F-35 as the volume fighter — The F-35 Joint Strike Fighter program was positioned as the more affordable, multi-role complement to the F-22, intended for much larger production numbers
  • Export ban — The Obey Amendment prohibited the export of the F-22 to any foreign nation, eliminating the possibility of spreading development costs across allied purchases. Japan, Australia, and Israel all expressed interest but were denied
  • Maintenance burden — The F-22's stealth coatings required extensive maintenance, and the aircraft's availability rate was initially lower than desired

The decision remains controversial. As China's J-20 entered service and Russia developed the Su-57, many analysts and former military officials argued that capping F-22 production at 187 aircraft was premature. The Air Force has consistently stated it needs more than 187 air superiority fighters to meet its global commitments.

F-22 vs F-35: Complementary 5th Generation Fighters

The F-22 and F-35 are often compared, but they were designed for fundamentally different roles and operate as complementary systems within the USAF force structure.

Characteristic F-22 Raptor F-35A Lightning II
Primary Role Air superiority Multi-role strike fighter
Engines Twin-engine (2 × F119) Single-engine (1 × F135)
Top Speed Mach 2.25 Mach 1.6
Supercruise Yes (Mach 1.82) No
Thrust Vectoring Yes (2D nozzles) No
Internal A/A Weapons 6 × AIM-120 + 2 × AIM-9 4 × AIM-120 (A/C variants)
Sensor Fusion Advanced Most advanced (newer generation)
EOTS / DAS No Yes (360° IR coverage)
Helmet Display No (standard HUD) Yes (helmet-mounted display)
Unit Cost ~$150 million ~$80 million
Planned Quantity 187 2,400+ (all variants)
Export Banned Exported to 15+ nations
Variants F-22A only F-35A, F-35B (STOVL), F-35C (carrier)

The F-22 excels in the air superiority mission: it is faster, more maneuverable, and carries more air-to-air missiles internally. Its supercruise capability and extreme agility make it the dominant platform in air-to-air combat. The F-35, meanwhile, was designed from the outset as a multi-role platform with more advanced sensor fusion, a distributed aperture system (DAS) providing 360-degree infrared coverage, and the ability to share data seamlessly across a networked battlespace.

In doctrine, the F-22 "kicks down the door" — penetrating enemy airspace first to destroy advanced air defenses and establish air superiority — while the F-35 follows to conduct strike, close air support, and sustained operations in the cleared environment.

F-22 vs Su-57: American and Russian 5th Generation Fighters

Russia's Sukhoi Su-57 Felon is the only other declared 5th generation fighter in service (apart from China's J-20) and is frequently compared to the F-22 Raptor.

Characteristic F-22 Raptor Su-57 Felon
First Flight 1997 2010
IOC 2005 2020 (limited service)
Stealth All-aspect, very low RCS Reduced RCS, primarily frontal aspect
Engines 2 × F119 (production engines) 2 × AL-41F1 (interim) / Izdeliye 30 (planned)
Supercruise Mach 1.82 Claimed with Izdeliye 30 engine
Thrust Vectoring 2D (pitch only) 3D (all-axis)
Top Speed Mach 2.25 Mach 2.0
Radar AN/APG-77 AESA N036 Byelka AESA (multiple arrays)
Internal Weapons 6 AIM-120 + 2 AIM-9 4–6 missiles (various types)
Produced 195 (complete) ~30 (as of 2025, production ongoing)
Unit Cost (est.) $150 million $35–50 million (estimated)

The F-22 holds significant advantages in stealth and proven combat capability. The Raptor's all-aspect stealth is considered far superior to the Su-57's, which features exposed engine faces, gaps between movable control surfaces, and a generally less refined low-observable design. The Su-57's round engine nozzles, in particular, are a major radar and infrared signature concern compared to the F-22's flat, serrated exhausts.

The Su-57's potential advantages include 3D thrust vectoring (versus the F-22's 2D pitch-only system), a distributed radar system with multiple AESA arrays providing wider angular coverage, and an infrared search-and-track (IRST) system that the F-22 lacks. However, the Su-57 has been produced in very small numbers, has not seen significant combat testing in the air superiority role, and its claimed capabilities remain largely unverified.

Key Design Features

Airframe

The F-22's airframe is constructed from a combination of titanium alloys (39%), composite materials (24%), aluminum (16%), and thermoplastic materials. The extensive use of titanium provides strength at the high temperatures encountered during sustained supersonic flight while keeping weight manageable. The diamond-shaped wing planform with 42-degree leading edge sweep provides a balance of supersonic performance, subsonic agility, and stealth.

Internal Weapons Bays

The F-22 was the first operational fighter to carry all of its primary weapons internally. The main ventral weapons bay measures approximately 4.9 m (16 ft) long and can accommodate six AIM-120 AMRAAMs on a hydraulic trapeze launcher, or two 1,000 lb JDAMs plus two AIM-120s. Two side-mounted bays each carry a single AIM-9 Sidewinder on a hydraulic arm that extends the missile into the airstream before launch.

Cockpit

The F-22's cockpit features a wide-angle head-up display (HUD), six color liquid crystal multifunction displays, and hands-on-throttle-and-stick (HOTAS) controls. The cockpit was designed with an emphasis on situational awareness, allowing the pilot to manage the complex battlespace environment with minimal heads-down time. The Martin-Baker US16E ejection seat provides zero-zero escape capability.

The Future: NGAD and the F-22's Replacement

The F-22 is expected to remain in USAF service into the 2030s, but the Air Force has already initiated work on its successor under the Next Generation Air Dominance (NGAD) program. NGAD is envisioned not as a single aircraft but as a "family of systems" that may include:

  • A crewed 6th generation fighter with advanced stealth, next-generation sensors, and potentially directed-energy weapons
  • Collaborative Combat Aircraft (CCA) — autonomous or semi-autonomous drone wingmen that operate alongside the crewed fighter
  • Advanced networking and battle management systems
  • New weapons systems including hypersonic missiles and long-range air-to-air missiles

The USAF confirmed in 2020 that a full-scale NGAD demonstrator had already flown, suggesting the program is well advanced. However, in 2024, the Air Force announced it was reassessing the NGAD program's scope and cost, with discussions about whether to proceed with a high-end crewed fighter or invest more heavily in autonomous CCA platforms.

Regardless of the NGAD outcome, the F-22 Raptor will be remembered as the aircraft that defined 5th generation air combat. Its combination of stealth, supercruise, sensor fusion, and agility set a standard that remains unmatched over two decades after its introduction. The lessons learned from the Raptor's design, production, and operation continue to shape every advanced fighter program in the world.

Legacy & Significance

The F-22 Raptor fundamentally changed air warfare. It demonstrated that stealth, speed, and information dominance could be combined in a single platform to create an overwhelming advantage in the air domain. In exercises, F-22s have achieved kill ratios as high as 108 to 0 against 4th generation adversaries like the F-15, F-16, and F/A-18.

"The F-22 is the most capable fighter ever built. Comparing a Raptor to an Eagle is like comparing an Eagle to a biplane." — Lt. Gen. John "Jumper" Corley, former ACC commander

In the Red Flag exercises held annually at Nellis AFB, F-22 pilots routinely dominate engagements, often engaging and destroying multiple adversary aircraft before the opponents even know a Raptor is in the fight. This performance has validated the core concept behind 5th generation air combat: the pilot who sees first, shoots first, and kills first wins.
