Although Germans had utilized seaplane tenders using engine steam to launch their Dornier Do J mailplanes on their South Atlantic Air Mail service as early as 1933, the modern steam catapult was a British invention.[5] The use of steam to launch aircraft was suggested by Commander Colin C. Mitchell RNVR,[6] and trials on HMS Perseus, flown by pilots such as Eric "Winkle" Brown, from 1950 showed its effectiveness. Navies introduced steam catapults, capable of launching the heavier jet fighters, in the mid-1950s. Powder-driven catapults were also contemplated, and would have been powerful enough, but would also have introduced far greater stresses on the airframes and may have been unsuitable for long use.
Nations that have retained large aircraft carriers and high performance CATOBAR (Catapult Assisted Take Off Barrier Arrested Recovery) (the United States Navy, Brazilian Navy, and French Navy) are still using catapults out of necessity. Other navies operate STOVL aircraft, such the Sea Harrier or AV-8B Harrier II, which do not require catapult assistance, from smaller and less costly ships. The Russian Su-33 "Flanker-D" can take off from aircraft carriers without a catapult, albeit at a reduced fuel and armament load. U.S. Navy tactical aircraft use catapults to launch with a heavier warload than would otherwise be possible. Larger planes, such as the E-2 Hawkeye and S-3 Viking, require a catapult shot, in as much as their thrust-to-weight ratio is too low for a conventional rolling takeoff on a carrier deck.]
