F/A-18 E/F 20mm Gun Gatling System

M61A1 Six-barrel Gatling Gun and Feed System
The F/A-18 E/F 20mm Gun System operates on the same proven principles that other General Dynamics 20mm Gatling gun systems use providing a wide array of extremely reliable features for positive round control throughout ammunition storage and the transfer cycle.
The F/A-18 E/F uses special materials and processes that yield extended life and reduced wear of the precision-engineered sprockets, guides, ammo drum and round paths. It also features proven gear box designs that provide reliable, precise and efficient power transfer.

The F/A-18 E/F’s components, including the gun, are mounted on a pallet structure. The gun is attached to the pallet via twin recoil adapters that dissipate firing forces. The entire system is mounted in the nose of the aircraft with barrel positioning provided by a forward muzzle clamp with integral rollers.

The palletized approach provides a straight-forward and rapid installation and removal process for ease of maintenance.
