It is the removed arm cannon of a guardian drone. It fires a ball of energy that acts as a grenade, bouncing and then exploding after a period of about 3 seconds. The projectile has the ability to move buses and cars before exploding.
This weapon is hard to use at first, but once one understands its operation, it becomes an extremely devastating weapon. A direct hit from the ball of energy will also deal high damage, and hitting a target's middle to upper body will usually result in the ball dropping straight down before exploding, making it a good way to hit specific targets with the explosion.
When fired into water, the projectile will continue normally, bouncing off any obstructions under the water. It will explode normally like other explosives.
The drone cannon can successfully fire about 417 times from full condition before breaking.
Drone cannon Ex-B - it has increased range over the drone cannon, and the projectiles fired from it explode on impact, unlike the bouncy drone cannon shot.

- Playstation 3 Xbox 360 When examining the drone cannon while in a guardian drone's inventory, the condition, damage, and value is at its highest (Full CND,152 DMG, Value:1999 caps) but when examining the drone cannon in the Wanderer's inventory, it will show its true statistics e.g. 3/4 CND,129 DMG, Value:1357 caps.

- ↑ Fallout 3 Official Game Guide Game Of The Year Edition p. 104: "Ripped from the mechanical body of an Alien Drone encountered throughout Mothership Zeta, this fires orb-like projectiles that bounce off walls and scenery and explode after around three seconds. It uses Alien Power Modules as ammunition. It inflicts two types of damage: collision (when the orb strikes a foe) and explosive (when the orb detonates). This can be extremely deadly once you learn when to fire, and how the orbs interact. It can fire over Alien Sphere Shields too, acting a little like a grenade."
