Description
Gray overall. Green tail struts. No color bands on the nose.
The bomb consists of a nose piece, barrel and tail assembly.
The slightly tapered longitudinally welded nose piece is closed at its forward end by a flat plate which has an 11 3/8 inch diameter. The plate is drilled centrally and this nose pocket can only accommodate a Navy gaine. A metal flange is welded to this plate. It is 5 1/4 inches long, 7/32 inch thick and has an 11 3/8 inch inner diameter. It is pierced by four 1/2 inch holes 3/4 inch aft of the forward end. The nose section is attached to the barrel by a continuous circumferential weld and 17 plug welds. There is a second circumferential weld at the point where the nose section begins to taper.
The barrel is of tubular steel construction.
The tail cone is attached by 30 plug welds to a coupling ring which fits inside the barrel. The coupling ring is held in the barrel by 2 rows of screws numbering 34 in all. There is a standard tail fuze pocket at the apex of the tail cone.
Four Navy type tail fins are welded to the tail cone. The fins are braced by a single set of box type struts.
The type 3 electric firing device is an influence fuze, operated by a photo-electric cell, which is activated by a beam of light projected from the fuze, and reflected from the target. Aerial burst at an altitude of 7 meters or above was desired by the designers. Fifty percent accuracy was considered to have been attained.
