The 12-inch H.C. projectile is merely a redesignation of the Mk 16. |
The Base Fuze Mk 39 repleaces the original "green stripe" Base Fuze Mk 28; the Auxili-ary Detonating Fuze Mk 35 replaces the original special "green stripe" Mk 17 Mod 8. These Fuzes are now being replaced by the Base Fuze Mk 48 and the Auxiliary Detonat-ing Fuze Mk 55. |
The Nose Fuze Mk 62 is the preferred nose time fuze. |
