The fastest fighter aircraft is the MiG 25, with speeds topping at Mach 3.2 (2,450 mph/4,000 km/h). Pilots were not allowed to go beyond Mach 2.8. Above Mach 2.8, the engines would overheat and burn up.
Most modern fighters can reach speeds of mach 2 or twice the speed of sound but rarely ever do so. Air engagements usually happen at 400 knots or so and acceleration is utilizâ¦ed for positioning more than anything. When needed this type of acceleration needs to happen pretty fast so a lot of power is needed.
