The F-22 Raptor's fuel consumption depends on its flight mode
The F-22 Raptor is a highly advanced fighter jet that combines stealth, supercruise, manoeuvrability, and integrated avionics with improved supportability. Its fuel consumption is dependent on its flight mode, with different modes offering varying levels of fuel efficiency.
When the F-22 engages its afterburners, it can achieve speeds of over Mach 2.0, or 2,414 kilometres per hour (1,500 mph). This speed is more than twice the speed of sound and provides a significant tactical advantage. However, this incredible speed comes at a cost. Afterburners inject extra fuel into the engine, providing a significant thrust boost. While this is excellent for short bursts of extreme speed, it is also extremely fuel-intensive and generates a significant heat signature, which can compromise the aircraft's stealth capabilities.
On the other hand, the F-22's supercruise capability allows it to sustain supersonic speeds without the use of afterburners. This mode offers greater fuel efficiency, enabling extended supersonic flight without excessive fuel consumption. Supercruise also allows the F-22 to maintain its stealth advantage, as it can achieve high speeds while remaining relatively stealthy due to the reduced heat signature. This tactical surprise gives the F-22 the ability to intercept enemy aircraft or engage in combat situations quickly and efficiently.
The exact fuel capacity of the F-22 is classified information, but estimates suggest it can carry around 8,165 kg (18,000 lbs) of internal fuel. For extended missions, the F-22 can utilise additional external fuel tanks, such as the 600-gallon tanks stored at Langley AFB in Virginia. These external tanks are designed to be jettisoned along with their pylons, allowing F-22 pilots to improve their stealth and performance when needed.
Overall, the F-22 Raptor's fuel consumption is dependent on the flight mode it is operating in. While it can achieve extremely high speeds with afterburners, this comes at the cost of fuel efficiency. The supercruise mode, on the other hand, offers a more fuel-efficient way to maintain supersonic speeds while preserving the aircraft's stealth capabilities.

Supercruise offers greater fuel efficiency than afterburner use
The F-22 Raptor is a dominant force in the skies, with a combination of unparalleled speed, stealth, manoeuvrability, and high-altitude performance. The F-22 Raptor's supercruise capabilities are touted as a major performance advantage over other fighters. Supercruise capability provides advantages for stealth aircraft because an afterburner plume reflects radar signals and creates a significant infrared signature. Afterburners also tend to guzzle fuel.
Supercruise is sustained supersonic flight without using an afterburner. The F-22 Raptor can supercruise above Mach 1.5 without external stores. Virtually all fighters prior to the F-22 cruise at Mach 0.8–0.9 while carrying a normal weapons load. The F-22 Raptor's supercruise capabilities are a significant increase in effective combat speed with a full weapons load.
The F-22's fuel consumption varies depending on its flight mode. Supercruise allows for extended supersonic flight without guzzling excessive fuel, giving the F-22 greater operational range and endurance. While the exact fuel capacity of the F-22 is classified information, estimates suggest it can carry around 8,165 kg (18,000 lbs) of internal fuel, with the option for additional external fuel tanks for extended missions.
The F-22 Raptor is a fifth-generation fighter incorporating fourth-generation technology, heightened manoeuvring capabilities, the ability to fly at supersonic speed without afterburners, and enhanced pilot situational awareness. The F-22 Raptor's supercruise capabilities are a testament to American engineering prowess.

The F-22 burns 60-65 gallons per minute at cruise
The F-22 Raptor is a fighter jet that combines stealth, supercruise, manoeuvrability, and integrated avionics with improved supportability. It is capable of both air-to-air and air-air-to-ground combat. The F-22 can achieve a top speed of Mach 2.0 (2,414 kilometres per hour or 1,500 miles per hour) with its afterburners engaged. This speed is more than twice the speed of sound.
Afterburners inject extra fuel into the engine, providing a significant thrust boost. This is excellent for short bursts of extreme speed but is very fuel-intensive. The F-22 burns approximately 60-65 gallons of fuel per minute at cruise. This fuel consumption is much higher than other aircraft, with one commenter on Reddit stating that the number "blows my mind".
The F-22 also has a supercruise capability, which allows it to sustain supersonic speeds without using afterburners. Supercruise offers greater fuel efficiency, giving the F-22 a longer range and endurance. This mode of operation also allows the F-22 to maintain its stealth capabilities, as afterburners generate a significant heat signature.
The exact fuel capacity of the F-22 is classified, but estimates suggest it can carry around 8,165 kilograms (18,000 pounds) of internal fuel. For extended missions, the F-22 can utilise external fuel tanks, such as the 600-gallon tanks stored at Langley AFB in Virginia. These tanks are designed to be jettisoned along with their pylons, allowing F-22 pilots to improve their stealth and performance when needed.

Afterburners inject extra fuel for a significant thrust boost
The F-22 Raptor is a highly advanced aircraft, capable of air-to-air and air-to-ground combat. It is a combination of stealth, supercruise, manoeuvrability, and integrated avionics, with improved supportability. One of the key features of the F-22 is its ability to use afterburners, which provide a significant thrust boost.
Afterburners are a set of fuel injectors that introduce additional fuel into the jet pipe downstream of the turbine. This extra fuel is burned using the leftover oxygen in the hot exhaust gases exiting the engine, providing an extra boost of power. The afterburner acts as a second combustion stage, significantly increasing the thrust of the engine without adding much weight or complexity.
The F-22's afterburners allow it to achieve speeds of up to 1.5 Mach (one and a half times the speed of sound) without even igniting its afterburner. When the afterburners are engaged, the aircraft can reach even higher speeds, making it highly manoeuvrable and agile.
However, the use of afterburners comes at a cost. Afterburners have a high fuel consumption rate, with estimates ranging from 50 to 65 gallons per minute. This fuel inefficiency limits their use to short durations, such as during take-off or in combat situations where a burst of speed is required. For this reason, afterburners are typically used sparingly and are more commonly seen on military jets than on commercial airliners, where efficiency is prioritised over short-term speed boosts.
Despite their fuel consumption, afterburners remain a valuable tool for aircraft like the F-22 Raptor. They provide a significant thrust boost without significantly increasing the weight or complexity of the engine, making them a critical component for aircraft requiring high-speed capabilities and manoeuvrability.

The F-22 can carry 8,165 kg (18,000 lbs) of internal fuel
The F-22 Raptor is a highly advanced fighter jet, with a combination of speed, stealth, manoeuvrability and high-altitude performance. Its fuel consumption varies depending on its flight mode. The F-22 can carry 8,165 kg (18,000 lbs) of internal fuel, but its exact fuel capacity is classified information. This internal fuel capacity is estimated, as the exact fuel capacity of the F-22 is classified.
The F-22's supercruise capability allows it to maintain supersonic speeds without using fuel-intensive afterburners, which inject extra fuel into the engine for a significant thrust boost. This fuel efficiency gives the F-22 greater range and endurance, allowing it to intercept enemy aircraft and engage in combat efficiently.
The F-22 can also be fitted with external fuel tanks for extended missions. These external tanks provide additional fuel capacity, but they can be jettisoned along with their pylons to improve the aircraft's stealth and performance when needed. The large external fuel tanks are stored in specialised facilities like the VTSS at Langley AFB, which houses the Raptor's 600-gallon external fuel tanks.
The F-22's fuel burn rate is estimated to be around 60-65 gallons per minute during cruise, which is still considered high even by fighter jet standards. This high fuel consumption is a trade-off for the aircraft's exceptional speed and performance, with the ability to cruise at over Mach 2.0, or twice the speed of sound.
