Description:
The Mk IV body consists of a hollow nose forging or casting, and a cast or forged tail adapter, welded to a sheet steel cas¬ing. The hollow nose is threaded to take a solid, fiat nose plug, which is secured by a locking screw. The carting is made of two part, welded together longitudinally. The tail adapter re¬ceives the exploder container, which is locked and scaled in position, and houses the detonator holder and pistol. The Mk III body has a nose fitted with a nose fuze adapter, three internal strengthening rings, and a tail adapter. A ballistic cap screws onto the nose to prevent ricochet. In the Mk VI body, the nose plug and a cup shaped nose attachment are welded on.
Use:
A.S. bombs, ranging from 100 to 600 lb. are at present in service use. They are thin-walled bombs, having a high charge/weight ratio for maximum blast effect on, or under, water. Air¬craft depth charges are used by the British as alternatives for these bombs.
Functioning:
The Bomb Mk IV uses a Tail Assembly No. 7 Mk I which consists of a sheet-metal tail Cone with a. Cylindrical strut attached by four fins. It is secured to the tail adapter by four spring clips on the cone. The tail assem¬bly also has a reach rod, with arming vanes on after end, which extends through the tail cone to en gape the arming fork of the tail pistol. The tail of the Bomb Mk III consist of a cylindrical strut, attached by fins to a dome, which is secured to the bomb by a central holt. The Bomb Mk VI uses a Tail No. 56 Mk I, which is secured by four locking screws threaded through four cone-securing bosses welded on at an angle to tail cone. The screws thread in¬ward and aft to engage slots in the bomb body.
