Trebuchet vs Catapult vs Ballista: 11 Critical Insights

by

Ballista vs Trebuchet vs catapult are all siege warfare engines but have some differences from which they gain some unique identities and characteristics. They are primarily used in the mediaeval period, around 400 BC to the 18th century. Trebuchet, catapult, ballista are ballistic weapons that throw projectiles like a boulder, burning charcoal, heavy darts etc. In this article, we will see the differences between Trebuchet vs catapult vs ballista and how it works? Their construction, etc.

Trebuchet vs Catapult vs Ballista

TrebuchetCatapultBallista
It is a mediaeval siege engine and successor of catapults.Catapults are the earliest siege machines in human history.and successor of catapults. Catapults are the earliest siege machines in human history. Ballista is the modern type of catapult
Mechanical advantage of a lever is used to throw projectileCatapults used torsion or tension in the skein to throw a projectile.Ballista also use torsion to throw the shot
It has a very long arm to hurl a projectile.Its arm is not as long as trebuchets.Ballista uses two levers, fixed in a twisted spring, to throw
Its long arm is pivoted on an axle in unequal proportion.Catapult arms one end is fixed in a twisted spring, and another lot have a bucket to carry projectile.It is more like a giant crossbow like structure, and both of its levers, one end, is fixed in springs. 
It can throw heavy objects to a very long distance.It can not throw heavy projectiles.It can throw heavy objects to a very long distance It can not throw heavy projectiles It can only throw small bolts and arrows specially made for it called darts
d 50 to 200 kg or more.It can throw a thing in 50 to 150 kg range.Ballista are not designed to throw heavy projectiles
It is a long-range engine but not precise in target hitting.It is not a long-range machine but very precise at target hittingIt is a long-range machine, exact in target hitting, and it can fire almost double to that of bow
It has two type
1- Traction Trebuchet
2- Counterweight trebuchet		It has four type
1- Trebuchet
2- Mangonel
3-Onager
4-Ballista		It has three type
1-Bontrager ballista
2- Roman ballista
3- Heavy ballista

trebuchet vs catapult

FeatureTrebuchetCatapult
TypeSiege engineSiege engine
MechanismUses a counterweight to swing a long arm and launch the projectileUses tension (either twisted rope or flexed wood) to launch projectiles
Historical UsageCame into widespread use in the Middle Ages, around the 12th centuryAncient and Medieval periods, with origins dating back to around 399 BC
RangeUp to 300 meters (980 feet) depending on the size and designGenerally shorter range, up to 200 meters (650 feet)
PayloadCan launch heavier projectiles, up to 140 kilograms (300 pounds)Typically lighter projectiles, around 15 to 20 kilograms (33 to 44 pounds)
AccuracyHigh accuracy with consistent counterweightLess accurate due to variations in tension force
ConstructionComplex to build and operate, requiring precise engineeringSimpler in design and easier to construct and operate
MobilityGenerally immobile due to size and weightMore mobile and versatile in placement on the battlefield
Energy SourceGravitational potential energy of the counterweightStored mechanical energy in twisted ropes or bent wood
Primary UseSiege warfare, capable of breaching fortificationsSiege warfare, anti-personnel, and breaching fortifications

This comparison emphasizes the catapult’s versatility and ease of use against the trebuchet’s superior power and range. Catapults were pivotal in both ancient and medieval warfare for various purposes, including breaching and anti-personnel actions. In contrast, trebuchets, which emerged prominently in the Middle Ages, specialized in demolishing fortifications with their hefty projectiles and extended range, showcasing advancements in siege technology and military engineering.
