120mm ventral gun

The 120mm ventral gun is a weapon mounted to the underside of the UNSC GA-TL1 Longsword.

Design details
The 120mm gun found on the Longsword is mounted underneath the craft, and cannot be used while the craft is grounded unless the ship's landing gear is extended. In this state, the gun has a ninety degree axis of rotation, and can fire relatively quickly - described as a "hail" of rounds fired in quick succession.

Operational history
During the capture of the Ascendant Justice by UNSC survivors of the Battle of Installation 04, a Longsword's 120mm ventral guns were used to clear one of the vessel's hangars of numerous Unggoy. The shells cut through unshielded Seraph-class starfighters, fuel pods, and the Covenant defenders with ease.
