Which country invented the aircraft carrier steam ejection technology?

The steam catapult was invented in August 1950. The prototype was developed by Mitchell, commander of the British naval aviation reserve, and the US Navy purchased the patent and developed it. At present, the C- 130 steam catapult equipped on the Nimitz-class aircraft carrier is 76.3 meters long and can eject two carrier-based aircraft every minute, which is powerful enough to eject a two-ton car to the sea two kilometers away.

Today, only the United States has fully mastered the steam catapult technology, and even the French nuclear-powered aircraft carrier "De Gaulle" has adopted the American steam catapult technology. Russia, Britain, Italy, Spain and other countries can't develop a steam catapult that can really pass the technical process. They can only use a sliding deck on their own aircraft carriers (that is, the end of the deck is turned into an uphill, and the carrier aircraft rushes out of the deck along the uphill after taking off, forming an oblique throwing motion), and the operational efficiency is far less than that of the steam catapult. Although the United States is ahead in the field of steam catapults, its inherent shortcomings determine that it will be replaced by newer technologies.
