Lockheed Martin F-22 Raptor

F-22 Raptor

The F-22A Raptor is a next-generation fighter/attack aircraft that features the latest stealth technology to reduce detection by radar. Using more advanced engines and avionics than the current F-15 Eagle, the F-22A is intended to maintain U.S. Air Force capabilities against more sophisticated enemy aircraft and air defenses in the 21st century.

The Raptor combines stealth, maneuverability and the ability to fly long distances at supersonic speeds — or “super cruise” — in performance of air superiority and air-to-ground missions. Furthermore, it requires less maintenance than older fighters. These capabilities represent an exponential leap in war fighting capabilities.

In 1981 the U.S. Air Force needed a new air superiority fighter that would take advantage of new technologies in fighter design including composite materials, lightweight alloys, advanced flight control systems, higher power propulsion systems and stealth technology. Lockheed Martin’s F-22 won the design competition in April 1991, and the rollout ceremony for the first F-22 Raptor occurred in April 1997.

The Raptor successfully completed its initial operational and test evaluation in 2004, and the program received approval for full rate production. In December 2005 operational aircraft were designated F-22As.

Production of the F-22A is a partnership between Lockheed Martin, Boeing and Pratt & Whitney. Boeing builds the Raptor’s wings and aft-fuselage; the engines come from Pratt & Whitney, and Lockheed Martin builds the forward fuselage and assembles the subsections in Marietta, Ga.

On May 12, 2005, the Raptor program achieved a historic milestone with the delivery of the first combat-capable Raptor to the 27th Fighter Squadron, 1st Fighter Wing, at Langley Air Force Base, Va. In January 2006 the 27th Fighter Squadron flew the first operational mission with the F-22 in support of Operation Noble Eagle (the official name given to the defense of U.S. borders).

A combination of sensor capability, integrated avionics, situational awareness, and weapons provides first-kill opportunity against threats. The F-22A possesses a sophisticated sensor suite allowing the pilot to track, identify, shoot and kill air-to-air threats before being detected. Significant advances in cockpit design and sensor fusion improve the pilot’s situational awareness. In the air-to-air configuration the Raptor carries six AIM-120 AMRAAMs and two AIM-9 Sidewinders.

The F-22A has a significant capability to attack surface targets. In the air-to-ground configuration the aircraft can carry two 1,000-pound GBU-32 Joint Direct Attack Munitions internally and will use on-board avionics for navigation and weapons delivery support. In the future air-to-ground capability will be enhanced with the addition of an upgraded radar and up to eight small diameter bombs. The Raptor will also carry two AIM-120s and two AIM-9s in the air-to-ground configuration.

Advances in low-observable technologies provide significantly improved survivability and lethality against air-to-air and surface-to-air threats. The F-22A brings stealth into the day, enabling it not only to protect itself but other assets.

The F-22A engines produce more thrust than any current fighter engine. The combination of sleek aerodynamic design and increased thrust allows the F-22A to cruise at supersonic airspeeds (greater than 1.5 Mach) without using afterburner — a characteristic known as super cruise. Super cruise greatly expands the F-22A ‘s operating envelope in both speed and range over current fighters, which must use fuel-consuming afterburner to operate at supersonic speeds.

The sophisticated F-22A aero design, advanced flight controls, thrust vectoring, and high thrust-to-weight ratio provide the capability to outmaneuver all current and projected aircraft. The F-22A design has been extensively tested and refined aerodynamically during the development process.

From the very beginning, the F-22A exceeded the USAF’s expectations, and during exercises and deployments, it proved to be more than a match for any fighter opposing it.

During the highly realistic Exercise Northern Edge 2006, the F-22 proved itself against as many as 40 “enemy aircraft” during simulated battles. The Raptor pilots achieved a 108-to-zero “kill” ratio against the best F-15, F-16 and F-18 “adversaries.” The stealthy F-22A also proved that it could avoid and destroy enemy surface to air missiles, and recorded an impressive 97 percent mission capability rate.

Specifically noting the Raptor’s performance at Northern Edge, the National Aeronautic Association (NAA) awarded its 2006 Robert J. Collier Trophy, considered America’s most prestigious award for aeronautical and space development, to the Lockheed Martin Corp.-led F-22 Raptor aircraft team “for designing, testing and operating” the Raptor. Team members included Lockheed Martin, Boeing, Pratt & Whitney, Northrop Grumman, Raytheon and BAE Systems. This amazing aircraft was described as “the most efficient and effective fighter in history, through exceptional performance and outstanding safety features.”

The F-22A will have better reliability and maintainability than any fighter aircraft in history. Increased F-22A reliability and maintainability pays off in less manpower required to fix the aircraft and the ability to operate more efficiently.

Boeing (McDonnell Douglas) F/A-18 Hornet and Super Hornet

Boeing F/A-18 Hornet
The F/A-18 “Hornet” is a single- and two-seat, twin engine, multi-mission fighter/attack aircraft that can operate from either aircraft carriers or land bases. The F/A-18 fills a variety of roles: air superiority, fighter escort, suppression of enemy air defenses, reconnaissance, forward air control, close and deep air support, and day and night strike missions. The F/A-18 Hornet replaced the F-4 Phantom II fighter and A-7 Corsair II light attack jet, and also replaced the A-6 Intruder as these aircraft were retired during the 1990s.

The F/A-18 has a digital control-by-wire flight control system which provides excellent handling qualities, and allows pilots to learn to fly the airplane with relative ease. At the same time, this system provides exceptional maneuverability and allows the pilot to concentrate on operating the weapons system. A solid thrust-to-weight ratio and superior turn characteristics combined with energy sustainability, enable the F/A-18 to hold its own against any adversary. The power to maintain evasive action is what many pilots consider the Hornet’s finest trait. In addition, the F/A-18 was also the Navy’s first tactical jet aircraft to incorporate a digital, MUX bus architecture for the entire system’s avionics suite. The benefit of this design feature is that the F/A-18 has been relatively easy to upgrade on a regular, affordable basis.

Making the first flight in November 1978, the F/A-18 and its two-place derivative [subsequently redesignated the F/A-18B] underwent most of their development testing at the Naval Air Test Center under the new single-site testing concept. While much attention was focused on development problems, these were largely typical of those in any new program, with their resolution being part of the development process. For the most part, these occurred in the basic aircraft hardware rather than in the digital electronic systems.

The original F/A-18A (single seat) and F/A-18B (dual seat) became operational in 1983 replacing Navy and Marine Corps F-4s and A-7s. It quickly became the battle group commander’s mainstay because of its capability, versatility and availability. Reliability and ease of maintenance were emphasized in its design, and F/A-18s have consistently flown three times more hours without failure than other Navy tactical aircraft, while requiring half the maintenance time.

The Hornet has been battle tested and has proved itself to be exactly what its designers intended: a highly reliable and versatile strike fighter. The F/A-18 played an important role in the 1986 strikes against Libya. Flying from USS CORAL SEA (CV 43), F/A-18s launched high-speed anti-radiation missiles (HARMs) against Libyan air defense radars and missile sites, effectively silencing them during the attacks on Benghazi facilities.

Following a successful run of more than 400 A and B models, the US Navy began taking fleet deliveries of improved F/A-18C (single seat) and F/A-18D (dual seat) models in September 1987. These Hornets carry the Advanced Medium Range Air-to-Air Missile (AMRAAM) and the infrared imaging Maverick air-to-ground missile. Two years later, the C/D models came with improved night attack capabilities. The new components included a navigation forward looking infrared (NAVFLIR) pod, a raster head-up display, night vision goggles, special cockpit lighting compatible with the night vision devices, a digital color moving map and an independent multipurpose color display.

F/A-18Cs have synthetic aperture ground mapping radar with a Doppler beam sharpening mode to generate ground maps. This ground mapping capability that permits crews to locate and attack targets in adverse weather and poor visibility or to precisely update the aircraft’s location relative to targets during the approach, a capability that improves bombing accuracy. New production F/A-18Cs received the APG-73 radar upgrade radars starting in 1994, providing more precise and clear radar displays.

The F/A-18C Nigh Attack Hornet has a pod-mounted Hughes AN/AAR-50 thermal imaging navigation set, a Loral AN/AAS-38 Nite Hawk FLIR targeting pod, and GEC Cat’s Eyes pilot’s night vision goggles. Some 48 F/A-18D two-seat Hornets are configured as the F/A-18D (RC) reconnaissance version, with the M61A1 cannon replaced by a pallet-mounted electro-optical suite comprising a blister-mounted IR linescan and two roll-stabilized sensor units, with all of these units recording onto video tape.

On the first day of Operation Desert Storm, two F/A-18s, each carrying four 2,000 lb. bombs, shot down two Iraqi MiGs and then proceeded to deliver their bombs on target. Throughout the Gulf War, squadrons of U.S. Navy, Marine and Canadian F/A-18s operated around the clock, setting records daily in reliability, survivability and ton-miles of ordnance delivered.

The multi-mission F/A-18E/F “Super Hornet” strike fighter is an upgrade of the combat-proven night strike F/A-18C/D. The Super Hornet will provide the battle group commander with a platform that has range, endurance, and ordnance carriage capabilities comparable to the A-6 which have been retired. The F/A-18E/F aircraft are 4.2 feet longer than earlier Hornets, have a 25% larger wing area, and carry 33% more internal fuel which will effectively increase mission range by 41% and endurance by 50%. The Super Hornet also incorporates two additional weapon stations. This allows for increased payload flexibility by mixing and matching air-to-air and/or air-to-ground ordnance. The aircraft can also carry the complete complement of “smart” weapons, including the newest joint weapons such as JDAM and JSOW.

The Super Hornet can carry approximately 17,750 pounds (8,032 kg) of external load on eleven stations. It has an all-weather air-to-air radar and a control system for accurate delivery of conventional or guided weapons. There are two wing tip stations, four inboard wing stations for fuel tanks or air-to-ground weapons, two nacelle fuselage stations for Sparrows or sensor pods, and one centerline station for fuel or air-to-ground weapons. An internal 20 mm M61A1 Vulcan cannon is mounted in the nose.

Carrier recovery payload is increased to 9,000 pounds, and its engine thrust from 36,000 pounds to 44,000 pounds utilizing two General Electric F414 turbo-fan engines. Although the more recent F/A-18C/D aircraft have incorporated a modicum of low observables technology, the F/A-18E/F was designed from the outset to optimize this and other survivability enhancements.

The Hughes Advanced Targeting Forward-Looking Infra-Red (ATFLIR), the baseline infrared system for the F/A-18 E/F, will also be deployed on earlier model F/A-18s. The Hughes pod features both navigation and infrared targeting systems, incorporating third generation mid-wave infrared (MWIR) staring focal plane technology.

The aircraft made its debut at Patuxent River (Md.) Naval Air Station in September 1995. The F/A18-E/F has achieved many milestones since its debut. The most significant was initial sea trials aboard USS John C. Stennis (CVN 74), the Navy’s newest aircraft carrier. These first Super Hornet carrier qualifications occurred in January 1997 off the coast of Florida, and consisted of a series of tests including catapult launches, arrested landings and various other system evaluations conducted by flight deck crews.

The Super Hornet is fully capable to conduct both air-to-air and air-to-ground combat missions. This includes air superiority, day/night strike with precision-guided weapons, fighter-escort, close air support, suppression of enemy air defenses, reconnaissance, forward air control and refueling. The Super Hornet has greater range/endurance, can carry a heavier payload, has enhanced survivability, and a built-in potential to incorporate future systems and technologies.
