ThrustSSC, Thrust SSC or Thrust supersonic car is a British jet car developed by Richard Noble, Glynne Bowsher, Ron Ayers, and Jeremy Bliss. Thrust SSC holds the world land speed record, set on 15 October 1997, when it achieved a speed of 1,228 km/h (763 mph) and became the first land vehicle to officially break the sound barrier.

The car was driven by Royal Air Force fighter pilot Wing Commander Andy Green in the Black Rock Desert in the state of Nevada. It was powered by two afterburning Rolls-Royce Spey turbofan engines, as used in the British version of the F-4 Phantom II jet fighter. The car is 16.5 metres long and 3.7 metres wide and weighs nearly 10 tons. It had a total thrust of 223 kN (approximately 50,000 pounds force), equivalent to around 102,000 brake horsepower at the measured record speed (calculated using Power = Force x Velocity).
