British Bomb, 250 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 a 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 Tail No. 10 Mk I has a tail cone with a cylindrical strut attached by 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 III has no spring clips, while the Tail No. 3 Mk I used on Bombs Mk IIC, 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.

Tail fins are usually painted red when the Time Pistol No. 37 is used.

Any mark may be found fitted with a copper driving band for proof firing from the B.L. 9.2-in. howitzer.
