Mk 72 and Mk 73 VT-RF Fuzes

This might not be that helpful, but the Mk 72 and Mk 73 VT-RF Fuzes are listed in NAVORD OP 2215 Volume 1 Second Revision on pages 3-88 and 3-91 respectively. Unfortunately, the copy I have at home ends at page 3-20. I will check at work tomorrow and see if we have a complete copy.

Thanks for the info, i do not have a copy of that. If you are able to find out more from your copy that would be great.

Thanks,

Mk 73 VT-RF Fuzes

I was unable to find the OP2215 publication I was looking for, however, I did manage to find a little information on the Mk 73 VT-RF Fuze.

The latest model of fuze in the series, is the Mk 73 Mod 13. The fuze has solid state electronics and contains an impact switch to ensure a point detonating back up to the primary radio proximity functioning mode should the proximity element fail to function. The Mod 13 is a non-self-destroying (NSD) fuze and is identified as such by having a green plastic nose.

NOTE - Non-self-destroying fuzes in this series carry odd-numbered Mods, eg, 9, 11, 13 and plastic nose pieces are coloured green. Self-destroying (SD) fuzes carry even-numbered Mods, eg, 8, 10, 12 and plastic nose pieces are coloured white.

All fuzes in the Mk 73 series have the wave suppression feature.

The exterior configurations of Mods 4 through 13 are identical with respect to thread, ogive and intrusion. Changes were made in the later mods to increase handling safety of the electric detonator and safety and reliability in gunfiring.

Unfortunately, I do not have any information specific to the Mod 10, but hope this helps.

I'm sure Darren will be thanking you for that information, but I would like to do likewise. I wasn't aware of the Mod numbers being used to identify NSD and SD types. Good to know.

Where could a guy like me get a copy of OP 2215, even it's only partial? I have OP 1480 but it only goes to 1946 and doesn't cover any of the VT fuzes after MK 59.

Or, any other OPs after 1480 that cover VTs.

Thanks again
