How fast do fighter jets fly? Fighter aircraft are noted for their amazing speed, which can often exceed supersonic speeds. Modern fighter jets, such as the F-22 Raptor and the Eurofighter Typhoon, may reach speeds greater than Mach 2, or more than 1,500 mph (2,414 km/h). These high speeds are critical to their role in military operations, allowing them to intercept enemy aircraft, avoid hazards, and engage in combat at lightning-fast rates. A fighter jet's maximum speed is frequently limited by air resistance, fuel efficiency, and the pilot's physical ability, as such speeds can result in extreme g-forces. Furthermore, while fighter planes may fly exceedingly quickly, their speed is frequently limited during peacetime operations to save fuel and protect safety.
