Ballista vs. Catapult — What's the Difference?
By Tayyaba Rehman & Fiza Rafique — Updated on May 9, 2024
A ballista is a missile weapon that launches bolts or large arrows, utilizing torsion springs, while a catapult primarily uses tension or torsion to hurl stones or projectiles.

Key Differences
The ballista operates similarly to a giant crossbow, designed to shoot large bolts or stones with precision, whereas catapults are often associated with hurling large stones or spherical projectiles over a longer distance.
The ballista was used for targeting specific points, such as personnel or small sections of fortifications, due to its accuracy, while the catapult was more effective for smashing walls or delivering payloads over and into enemy fortifications.
In terms of design, ballistas utilize two wooden arms and a torsion-powered mechanism, contrasting with catapults, which can vary in design from a simple slingshot mechanism to a more complex torsion-based system like the onager.
The loading mechanism of a ballista involves pulling back a winch to twist the skeins of the torsion springs, storing energy efficiently; on the other hand, catapults may use a winched arm or a twisted rope to build potential energy.
The projectiles used in ballistas are typically bolts or arrows, which can be enhanced with fire or other elements, while catapults often launch larger, more varied ammunition such as stones, fire pots, or even deceased infected animals to spread disease within enemy lines.

Ballista
The ballista (Latin, from Greek βαλλίστρα ballistra and that from βάλλω ballō, "throw"), plural ballistae, sometimes called bolt thrower, was an ancient missile weapon that launched either bolts or stones at a distant target. Developed from earlier Greek weapons, it relied upon different mechanics, using two levers with torsion springs instead of a tension prod (the bow part of a modern crossbow).

Common Curiosities
In what contexts were ballistas and catapults typically used?
Ballistas were used in both open field and siege warfare for precise attacks; catapults were predominantly siege weapons.
What types of projectiles did each use?
Ballistas fired bolts or arrows, while catapults could launch stones, fire pots, and more.
Which was more accurate, a ballista or a catapult?
The ballista was more accurate, suited for hitting specific targets.
What distinguishes a ballista from a catapult in terms of operation?
A ballista uses torsion springs for launching, focusing on precision; catapults generally use tension or torsion, aiming for power and range.
Could both weapons break through walls?
Catapults were more effective for breaching walls due to their power; ballistas were better for damaging structures and personnel without necessarily breaching them.
Are ballistas and catapults from the same historical period?
Both originated in ancient times but saw extensive use and development through the medieval period.
What was the range comparison between the two?
Generally, catapults had a longer range compared to ballistas.
What was the main tactical advantage of a ballista?
Its ability to target and disable specific enemy assets with high accuracy.
Could either weapon be operated by a single person?
Both weapons typically required a team to operate efficiently due to their size and the strength needed to load and fire.
Were replicas of these weapons used in modern times for any purpose?
Yes, replicas have been constructed for educational purposes, historical reenactments, and entertainment.
Which required more skill to operate?
Both required considerable skill, but ballistas demanded more precision in aiming.
Did the construction materials differ significantly between the two?
Both primarily used wood, metal, and rope, but the specific configurations and requirements could vary greatly.
How did the sizes of the two compare?
Sizes varied widely, but catapults, especially those designed for siege, were typically larger.
Was the ballista considered more advanced technology than the catapult?
Technologically, both had sophisticated designs, but the ballista’s mechanism allowed for greater precision, reflecting a different kind of advancement.
What is a common misconception about catapults and ballistas?
A common misconception is that they served the same tactical purposes; in reality, their designs and uses were quite distinct, with different strategic advantages.
