GERMAN 15 cm (NAVAL) A.P.B.C. SHELL
(Fig. 15)

This is a naval shell and is fired with a separate loading Q.F. cartridge. The approximately length of the shell is 24.8 inches and its weight filled and fuzed is approximately 99 lb.

The exterior of the shell is painted yellow and stencilled in black and has a black painted tip on the ballistic cap. A large arrow on the ballistic cap, painted in black and pointing towards the base, readily distinguishes this shell with a brass fuze from the H.E. shell which is similarly marked but has a nose fuze under the ballistic cap. The shell is fitted with two copper driving bands and, immediately behind the driving band, a lead ring which acts as a decoppering agent. The light blue ballistic cap is screwed on to an adap-ter secured to the shoulder of the shell body.

External markings on the shell are shown in Fig. 15.

The base of the shell cavity is screwthreaded to receive a flanged base adapter which screws on to a lead washer fitted against a shoulder formed in the shell cavity below the tread. The adapter is screwthreaded internally to receive a steel container, for the gaine and fuze, which extends into a cavity in the bursting charge.

The bursting charge weighs 4 lb. 7 1/2 oz. and consists of five pressed blocks of T.N.T./ Wax corresponding in setting point to Service Grade 1. Between the whole charge and the walls of the shell are two sheets of paper. The forward block consists of 6 oz. TNT/ Wax 75/25 in an aluminium container suitably shaped to fit the upper end of the shell cavity. The remaining blocks are contained in a card-board carton and consists of two upper blocks of 13 oz. TNT/Wax 80/20 and 1 lb. 0 1/2 oz. TNT/Wax 85/15 respectively, followed by two blocks consisting of 2 lb. 4 oz. TNT/Wax 95/5. The upper of the lower two blocks has a base cavity which, with the annular shaped lower block, forms a suit-ably shaped cavity to receive the steel exploder container.

Cardboard washers are fitted between the base adapter and the base of the filling in order that the filling may be held securely in the shell cavity.
