What is the Difference Between Catapult and Trebuchet

Catapult and Trebuchet are a set of ancient weapons used to destroy walls and fortresses during war times. It is quite possible to think that Catapult and Trebuchet are the same, however, there are multiple differences between the two.

Catapult vs Trebuchet

The main difference between Catapult and Trebuchet is that Catapult is commonly used for hurling objects of small size and weight, while Trebuchet can throw heavy projectiles.

However, the above is not the only difference. A comparison between both the terms on certain parameters can shed light on subtle aspects:

Catapult is a device for shooting small stones. Catapult is made of a Y-shaped stick with a piece of elastic tied between the two top parts.

In simple terms, Catapult is a type of instrument or machine which can throw an object. Catapult is a device specially used to set in motion projectiles at a significant distance. Catapult is usually small in size.

Catapults are of different types, the commons ones being with twisted springs. Other types of Catapult include ballistae (Catapult used in ancient warfare for hurling large stones which worked through the action of twisting). The other widely used Catapult in medieval times included mangonel or onagers (specifically designed to throw heavy objects), sprinkled (more for use in a limited space), and finally Trebuchet.

Catapult can throw small objects (around in the range of 10-25 kg). Catapults can throw fire-producing or inflammable objects or even medium-large stones. Catapults have been used in war activities since ancient times. Catapult was considered as one of the effective weapons to destroy enemy key objects.  Catapult is also available in modern times, for example, a device like a slingshot can be considered as a Catapult. Also, if we consider the aspect of launching an aircraft from a navy ship, it is based on the mechanism of the working of Catapult.

Trebuchet is a large medieval siege engine for hurling missiles consisting of a sling on a pivoted wooden arm set in motion by the fall of a weight. The trebuchet was first coined in China and then later progressed on the West wherein there were multiple variations in the design and methods of working.

Trebuchet main features include heavy load carrying and a flexible strap or belt used in the form of a loop to support the loaded objects or to launch the projectiles. The trebuchet can be considered to have enormous power to throw even a horse (around 200 kg plus) up to 500 meters.

The trebuchet can be extremely heavy in size. Trebuchet is not easily movable and even if one has to move it may require significant manpower. Trebuchet will have 4 portions or parts: the first one is a motionless frame, the second one is a signal on a shaft, the third is a slingback to hold the load or object, and finally, the ropes on each side to pull down the beam.

Trebuchet is a type of Catapult. Also, there are other types of Trebuchet such as traction Trebuchet which is also known as mangonel (which uses manpower) and counterweight Trebuchet (which is extremely large).

Trebuchet is very popular amongst the people who engage in warfare as Trebuchet carries more impact when used compared to other weapons in the same category. The trebuchet was once considered as the preferred and the most effective weapon in the war until the appearance of guns and arms.

Catapult and Trebuchet have been used for a long time as war weapons. Both of them have their pros and cons. Catapult and Trebuchet were designed to throw huge objects at castle walls or forts to destroy the walls. However, of late, Catapult and Trebuchet have lost significance due to the advancement of other better automatic war weapons in the market.
