The Mk 31 projectile was originally designed to receive the Base Fuze Mk 13, which is now obsolete. The projectile will now be found fitted only with V.T. fuzes and a plug in the base. |
|
The Nose Fuze Mk 40 is replacing the Mk 32 and Mods. With these fuzes, the Auxiliary Detonating Fuze Mk 54 will be emplyoed, replacing the previously used Auxiliary Detona-ting Fuzes Mk 17 and Mk 46. |
|
When the V.T. Fuze Mk 53 is used, the projectile adapter is removed and the Auxiliary Detonating Fuze Mk 44 employed. |
|
This projectile is also issued B.L. & P. or B.L. & T. with an adpater and the Tracer Mk 6, or Cut-off Base Fuze Mk 13, for target practice. |
