The proposal herein outlined sets forth the exact method for control of an aircraft bomb, classified as Barrage Type, intended to be remotely flown, thence unerringly guided from a ground control position to its ultimate target. It is suggested to also consider it as an artillery supplement in the laying down of a barrage. In several different ways it is better for long-range intensive barrage than the huge rifles of artillery. It is contemplated to employ that part of the radio spectrum between 70 and 200 megacycles or thereabouts.
