The proposed layout uses twin eight-barrel 40 mm Gatling mountings to create a dense barrage against incoming missiles. Three installations would be arranged so that two could concentrate fire in any threatened direction. Multiple barrels are suggested to distribute heat. The expected defensive effect comes from placing a large volume of flak in the missile's path, although no trial results or engineering calculations are offered.

Overlapping fields of fire for a proposed 40 mm barrage defence
A proposed three-mount arrangement would let two 40 mm Gatling installations concentrate a barrage against an incoming missile.
