Some fighter jets can fly faster than sound without using extra fuel
The Eurofighter Typhoon can maintain supersonic speeds without using fuel-heavy afterburners, a rare engineering feat known as supercruise that allows for sustained high-speed flight and increased mission endurance.
Most fighter jets must engage fuel-thirsty afterburners to break the sound barrier, but the Eurofighter Typhoon achieves Mach 1.1 using only its dry engine thrust. This capability, called supercruise, is enabled by advanced EJ200 turbofans and a lightweight airframe composed of 85 percent carbon fiber composites.
