What is the fastest fighter jet in the world?
The fastest fighter jet ever created was the NASA/USAF X-15. It was an experimental aircraft that resembled more of a rocket with wings but managed to reach a record 4,520mph. The fastest fighter jet in the world today is the MiG-25 Foxbat, with a top speed of 2,190mph, half the speed of the X-15.
But how do those jets compare with the other fastest fighters ever created, as well as military aircraft still in service today? Every plane mentioned is capable of speeds over Mach 2.0, that’s faster than 1,320mph and means these jets are capable of flying at almost twice the speed of sound or faster.
What is Mach speed?
Mach speed is relative to the speed of sound. Sound travels at a speed of 332 m/s or 1195 km/hr or 717 miles/hour, otherwise known as Mach 1.0. When aircraft travel faster than the speed of sound, they break what is known as the ‘sound barrier’ that can often result in a sonic boom. Once aircraft are capable of travelling faster than the speed of sound, they become incredible fighting machines, intercepting other aircraft and targets over vast distances at great speed.
