ION CANNON is a legendary rocket launcher in Borderlands 3 manufactured by Vladof. It can only be obtained in Moxxi's Heist of the Handsome Jackpot from the Fabricator located in Jack's Secret.

Special Weapon Effects

Fun detected. Obliterate. – Drastically increased weapon damage. Consumes 6 ammo per shot. Has a weapon charge-up time. Fires a highly accurate laser.

Usage & Description

The ION CANNON is capable of one of the highest single-shot damage outputs in the game when fully charged. This, along with its pinpoint accuracy, means that this weapon can reliably kill most mob-type enemies in one to two hits, and can be used for sniping during Fight For Your Life. A short charge will increase the ION CANNON's damage by a decent amount, and a full charge takes a relatively short amount of time.

This pairs very well with any character, but especially so with Moze, due to skills like Forge allowing ammo regen of the ION CANNON, and a majority of her Demolition Woman skill tree buffing splash damage output, especially Torgue Cross-Promotion.

The ION CANNON notably synergizes with abilities that use overkill damage. The Enforcer Guardian Rank reward Overkill allows any other gun to become capable of one-shotting regular enemies after a kill, while Amara's Remnant will add overkill damage to her homing orb upon killing an enemy.


  • Its skin is similar to a low-rarity Hyperion weapon skin.
  • An ION CANNON with the Annexed prefix will consume one more ammo per shot (total 7) instead of doubling it (total 12).
  • The Fabricator boss drops an ION CANNON every time it is killed.
