Introduction
The designation F‑22 is most commonly associated with the United States Air Force’s fifth‑generation tactical fighter aircraft, the Lockheed Martin F‑22 Raptor. The F‑22 is notable for its advanced stealth, supercruise, sensor fusion, and agility, and it represents a major milestone in U.S. aerospace development. While the acronym “F‑22” can also be used in other contexts, such as specific military or industrial designations, this article focuses on the fighter aircraft, covering its development, design features, operational history, and the broader implications for air combat doctrine.
History and Development
Origins and Program Initiation
The concept of a sixth‑generation fighter had been discussed as early as the 1970s, but the United States entered a new era of fifth‑generation design with the Joint Strike Fighter (JSF) and the Advanced Tactical Fighter (ATF) programs in the 1980s. The ATF competition, intended to replace the aging F‑15 and F‑16 fleets, led to the development of the F‑22. In 1991, the U.S. Air Force formally adopted the ATF as the Fifth Generation Air Superiority Fighter (F‑22) program, and the project received the necessary funding and political support to proceed.
Contractual and Design Phases
In 1995, the Lockheed Martin Corporation secured the sole-source contract to design and produce the F‑22. The company’s design leveraged previous experience with the F‑117 stealth technology, the F‑15 combat airworthiness, and the stealthy F‑117 and F‑35. The initial prototype, codenamed “Raptor,” first flew in 1997. Subsequent flight tests in the late 1990s and early 2000s validated the aircraft’s high‑performance flight envelope, stealth characteristics, and integrated avionics suite.
Production and Service Entry
After extensive evaluation, the U.S. Air Force decided to procure 187 F‑22 aircraft, including both production and combat-ready units. Production officially began in 2002, and the first serial aircraft was delivered in 2005. The F‑22 entered operational service in 2008 after the completion of initial combat training and fleet integration. The aircraft remained in production until 2011 when the U.S. Congress limited further orders, citing cost overruns and shifting defense priorities.
Design and Technology
Stealth Architecture
The F‑22 incorporates several stealth techniques to reduce radar cross‑section (RCS) and infrared signature. Key design elements include faceted wing and fuselage surfaces, blended radar‑absorbing composites, and internal weapon bays that eliminate external hardpoints. The use of composite materials and low‑observable alloys minimizes radar returns, allowing the aircraft to penetrate advanced air defense networks.
Propulsion and Supercruise
The fighter is powered by two General Electric F119-PW-100 turbofan engines, each capable of providing a thrust of 33,000 pounds. The engines incorporate bypass designs that reduce acoustic signatures, and the aircraft is capable of supercruise - maintaining Mach 1.5 or higher without afterburner. This capability provides extended range and high‑speed transits, especially over contested areas.
Flight Control and Aerodynamics
Highly maneuverable flight is achieved through an advanced fly‑by‑wire system and a fly‑by‑wire thrust vectoring nozzle that can direct engine thrust in multiple axes. The variable‑geometry tailplane, known as the "Maneuvering Tailplane," further enhances agility at high angles of attack. The aircraft’s wing design incorporates leading‑edge slats and trailing‑edge flaps, enabling both high‑speed and low‑speed flight regimes.
Avionics and Sensor Fusion
The F‑22’s cockpit houses the Integrated Avionics and Control System (IACS), which integrates radar, electro‑optical/infrared sensors, electronic warfare suites, and communications systems into a single data network. The AN/APG‑77 radar provides phased‑array detection, track‑while‑scan, and multi‑target engagement. Sensor fusion algorithms combine data from multiple sources to generate a comprehensive situational awareness picture for the pilot.
Armaments and Payload
The aircraft is designed to carry a wide array of air‑to‑air missiles, including the AIM‑120 AMRAAM and AIM‑9X Sidewinder, as well as the AIM‑54 Phoenix in earlier versions. Internal bomb bays can accommodate the GBU‑32 JDAM, GBU‑57A/B massive bunker buster, and the AGM‑154 Joint Standoff Weapon. External hardpoints are limited to maintain stealth, but the aircraft can also deploy external pylons when operating from non-stealth missions.
Operational History
Training and Deployment
F‑22 units were first stationed at the U.S. Air Force’s primary fighter bases, including Joint Base Elmendorf–Richardson and Luke Air Force Base. The aircraft entered the Gulf of Aden for air policing and maritime strike missions in 2008, with initial sorties focusing on air-to-ground support and air superiority tasks. The pilot training program emphasizes both simulator-based instruction and real‑flight practice, ensuring mastery of the aircraft’s advanced systems.
Combat Missions
While the F‑22’s combat record is relatively limited due to its high cost and the preference for other platforms in many theaters, it has participated in a variety of operations. The aircraft has provided close air support in Iraq and Afghanistan and has served as a deterrent presence in the Persian Gulf. It has also been employed in air policing missions over the North Atlantic and European airspace, ensuring the defense of allied air sovereignty.
International Collaboration
Several allied nations expressed interest in acquiring the F‑22; however, export restrictions prevented transfer to foreign militaries. Nonetheless, the U.S. Air Force conducted joint exercises with partner forces, enabling interoperability with aircraft such as the Eurofighter Typhoon, F‑35 Lightning II, and various NATO fighters.
Variants and Upgrades
Block 1 and Block 2
Initial production included two blocks. Block 1 aircraft featured the basic systems and core weaponry, while Block 2 incorporated incremental improvements such as enhanced mission computers, updated cockpit displays, and improved electronic warfare capabilities. The transition between blocks was seamless due to modular design and commonality.
Proposed Block 3
During the early 2010s, discussions considered a Block 3 upgrade that would integrate advanced radar, better survivability against directed‑energy weapons, and higher capacity for electronic warfare. These plans were shelved due to budget constraints and shifting strategic priorities.
