Image Courtesy: USAFThe Lockheed Martin F-22 Raptor achieves an estimated0. 30 to 0. 37 miles per gallonwhile flying in supercruise, a figure that may seem incredibly inefficient at first glance. However, compared to other fighter jets attempting the same sustained supersonic speeds, the Raptor is significantly more fuel-efficient because it does not rely on fuel-hungry afterburners. The estimate is based on the F-22’s confirmed internal fuel capacity of18,000 pounds, or roughly2,687 gallons, and its ability to sustain speeds aboveMach 1. 5, approximately990 mph. While official fuel consumption data remains classified, the calculations align with publicly available aircraft specifications and engineering estimates,according to Simple Flying. Supercruise refers to sustained supersonic flight without using an afterburner, a capability that sets the F-22 apart from most operational fighter aircraft. Powered by two Pratt & Whitney F119-PW-100 turbofan engines, the Raptor can maintain these speeds while burning considerably less fuel than fourth-generation fighters, which typically require afterburners and achieve an estimated0. 11 to 0. 15 mpgunder similar conditions. Based on the estimated burn rate, the F-22’s internal fuel supply can support approximately45 to 60 minutesof continuous supercruise, translating to a maximum range of roughly750 to 990 milesbefore the aircraft must slow down or draw fuel from external tanks. Several operational factors influence the aircraft’s fuel efficiency. Flying at higher altitudes reduces aerodynamic drag, while a clean configuration without external fuel tanks minimizes resistance. Aircraft weight, outside air temperature, and aggressive maneuvering also affect fuel consumption. Even brief afterburner use can dramatically reduce efficiency during flight. Despite its impressive performance, experts caution that the published fuel economy figures are estimates rather than official measurements. The U. S. Air Force has not released detailed fuel burn data for the F-22’s engines, meaning the calculations are derived from confirmed specifications and comparable engine performance. The F-22’s supercruise capability remains one of its defining tactical advantages. Although the jet consumes enormous amounts of fuel by civilian standards, it can travel at sustained supersonic speeds far more efficiently than aircraft that depend on afterburners, allowing it to reach combat zones faster while preserving valuable fuel reserves.
