British Bomb, 4000 lb HC, Mk 1

 

1394-038

Description

The body is a cylindrical shell which has a hollow, conical nose piece welded to it, parallel sides, and a closing plate bolted to an angle ring. The angle ring is welded in position a short distance inside the after end. The shell is strengthened by a T-section beam welded to its inner surface. Steel blocks, constituting pads for suspension lug and hoisting brackets, are welded in the angles of the beam. The central tube is fitted over, and cemented to, the stem of the exploder container, extending almost to the closing plate. Two exploder containers are fitted near the rear of bomb at 45° angles to the strengthening beam.

The tail is a cylinder of lightgauge plate, closed at rear by a diaphragm plate which is welded in position. Tail securing screws thread into corresponding holes near the rear edge of the body shell. The forward portion of the cylinder has saw-cuts between adjacent screw clearance holes, so that the tail can be sprung into the rear of the bomb body.

A single suspension lug at the center of gravity is bolted to the body and internal strengthening beam.

This bomb may be fitted with a nose attachment to retard it in flight, consisting of a light-gauge plate around the forward end of the shell, which projects beyond it around the conical nose piece. Side fuze pockets are usually not used, but might contain a Time Pistol No. 47.
