British Bomb, 500 lb SAP, Mk 2, Mk 3, Mk 2C, Mk 3C, Mk 5



The Mk V body is forged steel with a pointed nose and an open base, threaded internally to receive the exploder container, which is cemented in position. The base of the body is threaded externally to receive the tail adapter, which is in form of a coned ring with four equi-spaced slots to receive the spring clips of the tail. Earlier marks were similar to the Mk V, with slight variations in the tail adapter.

The Tails Nos. 27 Mks I and II are the short-type tail unit with arming vanes protruding beyond the strut and fins. The Tail Assembly No. 11 Mk I consists of a tail cone with a cylindrical strut attached by means of four fins. It is attached to the bomb body by four spring clips. The arming spindle engages the fork in the tail pistol. The Tail No. 1 Mk I used on Bombs Mk II and Mk III has no spring clips, while the No. 4 Mk I tail used on Bombs Mk IIC and Mk IIIC does have spring clips.

A single suspension lug is secured to the body by four screws.

The Tail Fuze No. 30 has left-hand threads on the securing ring.

Use of the Tail Pistol No. 37 is unlikely, but if used, tail fins are usually painted red.

The Bomb Mk I is very old and will not be found. The Mk IV bomb was manufactured, but never filled.
