A nose cap may be threaded to the projectile body over the nose fuze for moisture proofing purposes.
When this projectile is used in the 6"/58 bag gun, the Primer Mk 15 Mod 1 is used.
The Auxiliary Detonating Fuze Mk 54 is replacing the Auxiliary Detonating Fuzes Mk 17 and Mk 46 in all assemblies.
A specially cavitized Mk 34 round, designed for use in the 6"/47 gun only, is being produced for assembly with the VT Fuze Mk 47. When this fuze is used, the Base Fuze Mk 28 is also employed, without tracer. This feature differs from other VT fuzed projectiles, which take no base fuze. The Auxiliary Detonating Fuze Mk 44 will be used only in conjunction with the VT Fuze Mk 47.
No information about functioning.
Nothing else to see.
