US VT (Proximity Fuze)

[Darren]

Obviously a US Navy VT fuze from the stencils but thats all i know about this one. Im looking for any info about this fuze, what type it is, what date, what it was used on etc.

Im also looking fo a photo of a sectioned/cutaway example or an internal diagram.

Stampings:

T80E6 LOT 2069

Some of the stencils are to faded to read but the others are:

US (picture of an anchor)
6-44
75H - 105H

It looks like all im missing on this fuze is the booster cup, if anyone has a spare for this fuze for sale id be interested.

Thanks
Darren

This one is one of the original WWII era fuzes for Army use. The 75H and 105H stand for the two howitzers it was designed for the 75mm howitzer and 105mm Howitzer. The T number means it was Test or Experimental before a regular M number (Model) was assigned to it.

Hi Darren,
besides the booster cup you need the S & A device also, which is missing in the base of this fuze. (It consists of 2 rotor type assemblies in a housing, where the booster charge is attached to it. See attached cutaway!

Since that fuze is incomplete it has little or no value. I would be happy to dispose of it for you. I'll even pay shipping.:tinysmile_twink_t:

That is a good one, one of the earliest. It doesn't appear in OP 1480 (1946). For some reason, the 1945 "US Navy Projectiles & Fuzes" has been removed from the Internet, and I was not smart enough to make a hard copy before they did. Maybe Mrfuze or HAZORD have a copy?

Thanks for the photos.

Can you tell us what the thread diameter and pitch is?

I'm assuming that the stencil 6-44 is the date 1944?

Thanks for the info Hazord, great stuff. Now I know what it is I can display it upon the shelf with the rest of my collection.

If it will help to get you started, I'd guess it's 2" x 12tpi.

Hi Ray,

Ive just had a measure, The internal diameter is 38mm.

38mm seems on the small side unless you're referring to the thread for the Aux Det. I was looking for the thread size for the fuze body, where it screws into the projectile.

Ah, I'm with you now. Just measured that part and yes it is 2 inches.

The T80 proximity fuze series went all the way to the T80E12 version that I know of and may have gone further. The T80E9 was adopted as the M97A1, but the fuze is now obsolete. Bob
