F22 Raptor

The F-22 Raptor is a fifth-generation, single-seat, twin-engine, all-weather stealth tactical fighter aircraft developed by Lockheed Martin and Boeing for the United States Air Force (USAF). It is considered one of the most advanced fighter jets in the world, with capabilities that include stealth, supercruise, maneuverability, and integrated avionics. Production of the F-22 was halted in 2011 due to high costs, and the total number of aircraft produced is 187. The F-22 is used primarily by the USAF and is not available for export to other countries.   

History

The development of the F-22 Raptor began in the 1980s as part of the USAF's Advanced Tactical Fighter program. The goal of the program was to develop a new generation of air superiority fighter to replace the aging F-15 Eagle and F-16 Fighting Falcon. Lockheed Martin and Boeing were selected as the primary contractors for the program, and the first F-22 prototype took its maiden flight in 1997.

The F-22 officially entered service with the USAF in 2005. However, the program encountered several delays and cost overruns, and the total number of aircraft produced was limited to 187 due to budget constraints. The F-22 was first used in combat in 2014, during operations against ISIS in Syria.

Range

The range of an F-22 Raptor is approximately 1,500 miles (2,414 kilometers) when flying at supersonic speeds, and approximately 1,200 miles (1,931 kilometers) when flying at subsonic speeds. This range can be extended by using external fuel tanks.

Speed

The F-22 Raptor is capable of flying at high speeds, both in supersonic and subsonic speeds. The aircraft is designed to achieve supercruise, which is the ability to fly at supersonic speeds without using afterburners. Supercruise allows the F-22 to fly at speeds of up to 1.5 Mach (1,183 mph, 1,905 km/h) without using additional fuel.

The F-22 also has a maximum speed of around Mach 2.25 (1,498 mph, 2,410 km/h) with afterburners. This allows it to outrun most other fighter aircraft. Additionally, the F-22 has a maximum altitude of over 60,000 feet (18,288m) and can climb to that altitude in less than 2 minutes. These speed and altitude capabilities provide the F-22 with a significant advantage in air-to-air combat, as it can quickly close in on an enemy aircraft without giving away its position and evade radar detection.

power

The F-22 Raptor is powered by two Pratt & Whitney F119-PW-100 turbofan engines, each capable of producing 35,000 pounds-force (156 kN) of thrust. These engines are designed to be highly stealthy and provide the F-22 with excellent performance and maneuverability. The F119 engine features a low-observable fan section, internal weapons bay, and a two-dimensional thrust vectoring nozzle. The F-22's engines are designed to allow the aircraft to supercruise, which is the ability to fly at supersonic speeds without using afterburners. This allows the F-22 to fly at speeds of up to 1.5 Mach (1,183 mph, 1,905 km/h) without using additional fuel. The engines also give the F-22 a maximum speed of around Mach 2.25 (1,498 mph, 2,410 km/h) with afterburners and a maximum altitude of over 60,000 feet (18,288m) and can climb to that altitude in less than 2 minutes. The F-22's engines are also designed to be highly reliable and require minimal maintenance, which reduces the aircraft's downtime and increases its availability for missions.

Fuel capacity

The F-22 Raptor has a fuel capacity of approximately 18,000 pounds (8,165 kg) of fuel. This fuel is stored in four internal fuel tanks, two in the main fuselage and one in each wing. The F-22's fuel system is designed to be highly efficient, allowing the aircraft to fly long distances and stay on station for extended periods. In addition, the F-22's engines are designed to be highly fuel-efficient, which helps to extend the aircraft's range and endurance. The F-22 also has the capability to carry external fuel tanks which can be attached to the hardpoints beneath the wings of the aircraft. This increases the aircraft's total fuel capacity and allows it to fly even longer distances. The use of external fuel tanks does however, reduce the aircraft's stealth capabilities as it increases the radar cross-section.

Price

The F-22 Raptor is one of the most expensive military aircraft ever built, with the unit cost of each aircraft being very high. The unit cost of the F-22 at the time of its production was around $150 million per aircraft in 1997 dollars, and it is estimated that the total program cost for the 187 aircraft produced was around $79.4 billion. However, it should be noted that these figures are from the time of the program and are likely to have increased due to inflation and other factors. Additionally, the cost of the aircraft does not include the cost of research and development, which was significant.

It's also worth noting that the F-22 was a relatively limited production aircraft and was not produced in large numbers like other fighter jets. The high unit cost is in part due to the advanced technology used in the aircraft and the high cost of research and development. Additionally, the F-22's capabilities make it a formidable weapon system and a key asset to the United States Air Force.

Characteristics

It has the following key characteristics:

Stealth: The F-22's design includes many features that make it difficult to detect by radar, including internal weapons bays, a low-observable fan section, and a two-dimensional thrust-vectoring nozzle.

Supercruise: The F-22 is designed to fly at supersonic speeds without using afterburners, which allows it to fly at speeds of up to 1.5 Mach (1,183 mph, 1,905 km/h) without using additional fuel.

Maneuverability: The F-22 is highly maneuverable, thanks to its advanced flight control system and thrust-vectoring nozzles, which allow it to perform high-G maneuvers and maintain control at high speeds.

Avionics: The F-22 is equipped with advanced avionics, including an active electronically scanned array radar, advanced electronic warfare systems, and a helmet-mounted cueing system.

Weapons: The F-22 can carry a variety of air-to-air and air-to-ground weapons, including AIM-120 AMRAAM missiles, AIM-9 Sidewinder missiles, and JDAM precision-guided bombs.

Speed and altitude: The F-22 has a maximum speed of around Mach 2.25 (1,498 mph, 2,410 km/h) and a maximum altitude of over 60,000 feet (18,288m).

Overall, the F-22 Raptor was designed as an air superiority fighter and it is one of the most advanced aircraft in the world.

Crashes

There have been several incidents and accidents involving the F-22 Raptor, some of which have resulted in crashes.

One of the early F-22 crashes occurred in 2010, when an F-22 crashed in Alaska, the pilot safely ejected. The cause of the crash was determined to be from a malfunction in the oxygen system that resulted in a loss of pilot consciousness.

Another crash occurred in 2012, an F-22 crashed in Florida, the pilot safely ejected. The cause of the crash was determined to be from a malfunction in the aircraft's left engine.

In 2018, an F-22 crashed outside of Anchorage, Alaska, the pilot was killed. The cause of the crash was determined to be from a malfunction in the aircraft's engine.

In 2019, an F-22 crashed in Florida, the pilot safely ejected. The cause of the crash was determined to be from a malfunction in the aircraft's engine.

It's worth noting that the F-22 has a relatively low accident rate compared to other military aircraft. The crashes that have occurred were not due to any inherent flaw in the aircraft's design, but rather were caused by specific malfunctions or equipment failures. The Air Force has taken steps to address these issues, such as upgrading the F-22's oxygen system and making changes to the aircraft's engine, to prevent similar incidents from happening in the future.
