The Leopard 2AV was a pre-production version of the Leopard 2, which was trialled by the US, against the XM-1, in the 1970's. One of the turrets provided had the new 120mm L/44 smoothbore cannon.
DM13 APFSDS was the first APFSDS projectile which entered service with the cannon, which featured 2 tungsten alloy cores in a maraging steel jacket. This projectile cores have a low aspect ratio for a long-rod projectile, resulting in the projectile's performance being only slightly better than projectiles like M774 and M111 Hetz. Due to this, DM13 was quickly superceeded by DM23, which was monolithic with a higher aspect ratio.
The T-72A upper glacis Rolled Homogenous Armour (RHA) has been modelled as ~300BHN. The geometry of DM13 was taken from this diagram: 1.bp.blogspot.com/-bhG8b8KUYd...

Interestingly, there are a few sources stating that DM13 APFSDS can penetrate 220mm RHA at 2km @60°, which I find extemely unlikely based on projectile diagrams and core weights available online. I'd be curious to know what others think about this!

@LMSscavenjer 7 месяцев назад

What is the total weight of the projectile you simulated? It should be 4.64kg according to the ammunition datasheet. I have some documents that state penetration at 2km on a NATO single target plate at 60°, it is much higher than the German TL target plates (213mm vs 178mm). It also provides the range at which it can penetrate the assumed T-64/72 hull armour of 100mm RHA at 70° at puts this at almost 4400m. The "reinfoced" T-64/72 hull armour of 15mm + 100mm at 70° can only be penetrated from a range of around 1500m. DM13 is heavily affected by spaced or complex armour at high angles due to the construction method.

@DarthEarp 7 месяцев назад

Bit of a joke idea. In the movie Delta Farce, the heroes use a Napoleon 12 pounder to disable an M4 Sherman. I know it is unlikely to penetrate, but would love to see a black powder cannon shoot at a tank, just to see what would happen, or how big you would need to do any real damage.

It’s not true that the 120mm demonstrated by the Germans showed significant improvement over the 105mm as demonstrated in tests at Watervliet Arsenal, NY. That’s why the Americans opted to hold off on the 120mm which would have delayed fielding the Abrams.

@downundergarage6968 4 месяца назад
