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. |
