The SR-72, designed by Lockheed Martin, is estimated to have a top speed of 7,400 km/h, making it the fastest aircraft in the world when tested in 2025. This speed is almost twice as fast as its predecessor SR- 71 Blackbird – the world’s fastest manned aircraft, which broke the speed record in 1974 but was discontinued in 1998.
With that super-fast speed, the SR-72 becomes a supersonic aircraft and can evade today’s jet fighters.
Supersonic aircraft are aircraft that fly faster than the speed of sound but do not reach the threshold of Mach 5. And aircraft with a minimum speed of 5 times of sound (Mach 5), or more than 6,200 km/h, are known as supersonic aircraft. supersonic aircraft.
The SR-72 is designed to be a reusable supersonic unmanned aerial vehicle, specialized for reconnaissance, surveillance and attack in hazardous environments where it can be too risky for dangerous environments. manned aircraft are slower.
The speed boost of the SR-72 is possible thanks to the new turbine-based combined cycle (TBCC) propulsion system combined with today’s dual-mode straight-line turbofan engines.
According to Lockheed Martin, the SR-72 prototype will take off for test flights in 2025 and may enter service in the 2030s.
Supersonic aircraft technology is becoming a global race. NASA will test-fly the silent supersonic X-59 next year.
