Basic diagram of an onager, a type of catapult. A catapult is a ballistic device used to launch a projectile a great distance without the aid of gunpowder or other propellants – particularly various types of ancient and medieval siege engines. [1] A catapult uses the sudden release of stored potential energy to propel its payload.
The catapult used on aircraft carriers consists of a track or slot built into the flight deck, below which is a large piston or shuttle that is attached through the track to the nose gear of the aircraft, or in some cases a wire rope, called a catapult bridle, is attached to the aircraft and the catapult shuttle.
A trebuchet [nb 1] (French: trébuchet) is a type of catapult [5] that uses a rotating arm with a sling attached to the tip to launch a projectile. It was a common powerful siege engine until the advent of gunpowder. The design of a trebuchet allows it to launch projectiles of greater weights and further distances than that of a traditional ...
The modern steam-powered catapult, powered by steam from the ship's boilers, was invented by Commander C.C. Mitchell of the Royal Naval Reserve. [27] 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 1940s.

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.
The Onager was a Roman torsion powered siege engine. It is commonly depicted as a catapult with a bowl, bucket, or sling at the end of its throwing arm. Trebuchet: 4th Century BC China: Similar to the catapult, but uses a swinging arm to launch projectiles. It is usually considered to be stronger than the catapult. [4] Oxybeles: 375 BC Greece
A catapulta was a Roman machine for throwing arrows and javelins, [1] [2] 12 feet (3.7 m) or 15 feet (4.6 m) long, at the enemy. The name comes from the Greek katapeltes (καταπέλτης), because it could pierce or 'go through' (kata) shields (peltas).
