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.
Based on the sources provided, I think the sentence is ok, since it says that Ajatshatru is recorded as having used a catapult. I don't want to add in OR on that front by claiming that this would be the first recorded use of catapults on a battlefield without consensus.
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.
F/A-18 attached to steam catapult preparatory to launch. A well-known type of assisted takeoff is an aircraft catapult. In modern systems fitted on aircraft carriers, a piston, known as a shuttle, is propelled down a long cylinder under steam pressure. The aircraft is attached to the shuttle using a tow bar or launch bar mounted to the nose ...

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 ancient Greek Helepolis, a massive siege tower which mounted catapults, could also be considered a weapons platform. The next attempt to mount weapons on platforms was made at sea, with catapults and eventually cannon mounted on their final form as ships of the line before the advent of ironclad warships mounting turrets.
The Flyer moved forward under its own engine power and was not assisted by catapult, a device the brothers did use during flight tests in the next two years and at public demonstrations in the U.S. and Europe in 1908–1909. A headwind averaging about 20 mph gave the machine sufficient airspeed to become airborne; its speed over the ground was ...
