Well Germany is in NATO and Japan is a close ally of the US.
And both coutries use JDAMS.
Also:
So here is a good source, nice!
So were are both correct and both wrong then. The L/44 can fire the DM53 but only if new recoil brakes are installed. But it does not require a new breach block as you started the discussion with saying:
You might have either mistyped or misunderstood what the k600-k900 serries ment?
And the increased max allowable from 740-760 to 760-780 MPa i didn’t know about and haven’t seen anywhere else. Thanks for the source to that. But it also shows that the breach and barrel of L/44 was more than capable of handling the DM53 but the issue was mainly a WAY greater ware on the barrel (the article even states that the L/55 uses the same breach as the L/44).
The image of the pressures of DM53 show that the pressure is under 650MPa at 45 degrees so still within the max allowable pressure for L/44.

Yes, I did. Both have B in them and my mind jumped to the breechblock since nobody ever thinks of the brakes lol.

No problem!
if you are interested as well; the Ariete uses the CL-3143 round (the M322 Israeli round) which is the same as the SLPPRJ 95 that Sweden uses. According to the Swedish army ammunition catalogue (AMKAT 2014) the SLPPRJ has a max pressure of 670Mpa (which is around the same as the DM53 going by the previous graph).
So the Ariete might also only need new brakes to be able to fire DM53.
I have no clue about the upgrade cycle of the Ariete though, is there a chance they upgraded the breaks on them?
pMax per NATO standard is the pressure generated at +/- 50 degrees, so DM53s still has a few pascals over it.
If my memory serves me correctly, Ariete’s Oto-Breda L/44 has an SMP/design pressure of about ~670 MPa, as such, M/95 is still considered safe, while DM53 by that alone would be regarded as too much.
I have no clue about the upgrade cycle of the Ariete though, is there a chance they upgraded the breaks on them?
No data. However, if their plains for the C2 (C3?) upgrade are anything to go by, not likely, as they’re looking towards their new L/45 which has similar pressure resistances to Germany’s L/55A1, and DM53 has only been trialed on the Centauro B2 so far (though, in this case, they’re looking more at DM73 & the future DM83)
