25pdr SP, tracked, Sexton MK II

In the latest update there is a French boat (made by Britain I believe) equipped with 25-Pdr guns. These guns have access to APC shells, so it’s likely we will see the same for ground vehicles with this gun too.

Hesh filling is likely 1.91kg of 86% RDX / 14% Wax.

That’s useful to know. Where did you find out about it?

I found it in the Australian archives, item no. 3254827. Preliminary info as it was still under test/development, so it is possible that that fill weight includes a small amount of inert cushioning material in the nose.

I tried searching for it on their site but couldn’t find it. They probably haven’t digitized it yet. Did you perchance happen to make a copy or take a photo of the document? Physical proof could really help out to put the shell in to the game. :)

+1, more representation for WWII howitzers!

Many thanks!

Some of the data I could get from it if anyone’s interested:

Spoiler

Date of testing: 1951/52 (Australia)
Filler Type: RDX/PWX 86/14 (TNTe = x1.28)
Filler Weight: 1.915 kg
Propellant Charge: Super charge. “Super charge plus” was considered but dropped later on.
Fuse: Similar to the LS Mk.1 fuze as used in the 120mm B.A.T. gun.

Penetration: Projected to defeat 4 inches (101.6mm) @30º-64º.

Was it adopted? Still not sure but one piece of text stood out suggesting it very likely was:

Shell drawing with data

Cool but quite a few stats for that shell seems to be wrong, they got the initial weight right, as it fires a 20 pound AP shell so 9.07 kg, but the shell type is wrong as it should be an APCBC shell or standard AP as they didnt do an APC shell. In addition they are firing it with only the HE charge, the AP and APBC shell for the 25 pounder was fired with a juicy Super and Super plus charge, which was done to ensure that the shell would strike enemy armour flat, that has the following statistic and would give a muzzle velocity of 609.6 meters a second. Its odd this is the case though, as the HE shell in game seems to have the right statistics, they have just borked the ap.

the fact the he shell is using the super charge means they have decided to model a mark 2 or later 25 pounder, as the earlier guns couldent handle the oomff

Perhaps a bug report is in order?

not really, as the real bug report would be to have it removed from the ship, as they loaded only HE, as it was for shore bombardment, like the rest of the landing ship gun variants.

We’re missing so many of these iconic vehicles. +1

No problem. I would be a little bit careful with it as that is just information supplied by the UK to Australia before the design was finalised and so it is subject to change. I have a vague recollection of the L8 fuze not being 100%, and so it ended up with the L19 fuze (I think).

I had wondered if the AP round on that French boat was using the strongest charge but hadn’t bothered to look in to it yet. Thanks for posting, suggests there’s a bit more pen to come from the 25pdr in tanks like the Sexton, A.C.III and Yeramba.

There is an APC round for the 25 pounder, APC MkVIIT although it seems to have been quite rare. I’d have more doubts about an APCBC as the only evidence I can recall ever seeing for it is one bad photo that appears to show a miss-labelled HE drill round instead.
