The most widely used catapults throughout the Middle Ages were as follows: [46] Ballista Ballistae were similar to giant crossbows and were designed to work through torsion. The projectiles were large arrows or darts made from wood with an iron tip. These arrows were then shot "along a flat trajectory" at a target.
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 might have been unsuitable for long use.

A slingshot or catapult is a small hand-powered projectile weapon. The classic form consists of a Y-shaped frame, with two tubes or strips made from either a natural rubber or synthetic elastic material. These are attached to the upper two ends. The other ends of the strips lead back to a pouch that holds the projectile. One hand holds the ...
The catapult was versatile, and could effectively launch any projectile that fit in its launch bucket. [34] The Romans also developed an automatic repeating catapult called the scorpion. This was smaller than other catapults but had more moving parts. The rope coils were often made of twisted bovine sinews, horsehair or women's hair.
About a third of the size of a fleet carrier, they carried between 20 and 30 aircraft, mostly for anti-submarine duties. Over 100 were built or converted from merchantmen. Escort carriers were built in the US from two basic hull designs: one from a merchant ship, and the other from a slightly larger, slightly faster tanker.
The modern steam-powered catapult, powered by steam from a ship's boilers or reactors, was invented by Commander C.C. Mitchell of the Royal Naval Reserve. [32] It was widely adopted following trials on HMS Perseus between 1950 and 1952 which showed it to be more powerful and reliable than the hydraulic catapults which had been introduced in the ...
It was launched from a spring-actuated catapult mounted on top of a houseboat on the Potomac River near Quantico, Virginia. Two flights were made that afternoon, one of 1,005 metres (3,297 ft) and a second of 700 metres (2,300 ft), at a speed of approximately 25 miles per hour (40 km/h).
