M632 105-MM CS projectile

**jvollenberg** · 27th January 2012, 03:34 PM

Does anyone have a M632 projectile or M632 105-MM CS cartridge (the cartridge contains the M632 projectile) they can take pictures of? I am in the process of updating this publication, and would like to get some real images of this item if possible.

Thanks,

Joe

Thanks

Some photos of my 105H XM-629 TAC-CS cartridge that uses an XM-632 projo body. Shown with an ILLUM and BE smoke to show the tighter radius of ogive on the ILLUM and TAC-CS compared to the larger radius of ogive (more tapered) on the rest of the 105 Howitzer family. The Illum and TAC-CS are very recognizeable by their ogive design. I'm puzzled as to why the weight zone markings were stamped in 90 degrees clockwise from the rest of the lettering. You will notice that the illum cartridge is an M314A3 and the projectile is an M314A3. I guess keeping the same number for cartridge and projo body on the TAC-CS would have been too simple.

Great pictures, do you have an example of the 155mm Projo?

Pete,

Here is the XM-631 155H projo. It is fired and I repainted it about 30 years ago. It is 23-3/8 inches tall without base plate or fuze. The base plate will add about 5/16 to 3/8 more.

It is shown with the 105H XM-629 projo above, which is just under 14-7/8 inches tall without base plate or fuze, and also shown with the 66mm CS rocket which is 20 inches long.

The 155mm projo appears to be identical in design to the 155mm M-485 ILLUM. It takes a 2 inch fuze and the base is press fit in and pinned the same as the ILLUM. BE smoke projectiles of this caliber typically have a screw in baseplate and take the smaller diameter 1.4 inch time fuze.
