Description
Gray overall with a green band forward of a blue band on the nose.
A cast steel nose is attached by a continuous circumferential weld and 16 plug welds to a longitudinally welded tubular steel body.
An anti-ricochet attachment consisting of a metal ring and two supporting plates is welded to the bomb at a point 1 3/4 inches forward of the junction of the nose and body. The ring has a 13 3/4 inch diameter, is 5 inches long and 5/32 inch thick. The two semicircular supporting plates are welded to the interior of the forward end of the ring and to the nose of the bomb. There are two notches cut into the forward edge of the ring 180° apart. One notch is in line with the suspension lug. The supporting plates fail to meet by % inch at the two notches.
A tail cone is attached to a collar by 36 screws. The collar is held in the base of the bomb body by a single row of 16 plug welds.
The tail is constructed in two sections: the first section has eight 1/8 inch sheet steel fins welded to the tail cone and supported by seven steel struts. The second section consists of eight plywood fins in steel frames supported at their inner edges by a metal cylinder 4 inches in diameter and on their outer edges by seven steel struts. The second section is attached to the first by bolted steel plates on each of the eight fins. Apparently the wooden tail section is designed to come off on water impact.
