European MGCS ( Main Ground Combat System)

[muttbutt]

Though they seem to be pitching it squarely at the MGCS program, whether in earnest or just to get some of the R&D funding is debatable of course.

Well they are calling this version the SHARD 120 which is a very variant specific name and leaves open other calibres for SHARD plus,

The validation and qualification of innovative technology building blocks in the SHARD programme is also one of the milestones in the development of very high performance ammunition for future land combat systems, in particular the Main Ground Combat System.

Seems like they have ideas going forward with the whole SHARD project.

Rheinmetall also seems to be busy on new rounds

Nexter has been busy...

Nexter is proposing the ASCALON concept ("Autoloaded and SCALable Outperforming guN") designed to cope with the latest generation of heavy armor while staying ahead of the threats of the next half-centur

Leaning on its expertise in battle tank armament, illustrated by the Leclerc's self-loading gun, and on the excellence of its ammunition activity, Nexter (KNDS group) is presenting ASCALON, a new main armament concept for main battle tanks, designed to deal with future heavily armored threats.

Modern sabot rounds are already heavily telescoped; this just takes it to the logical extreme by pushing the sabot all the way to the front of the dart and filling the volume of the case behind it. NEXTER has some experience with "puller" sabots like this, thanks to 40 CTA.

Just guessing that this is a 140mm gun, with a dart around 1 meter long.

Edit: interestingly, this telescoped round is about the same length overall as the new Rheinmetall 130mm design, at 1.3m.

Well let's see if anyone would complain about Bore Riding points like what they did for Russian rounds.

Then that dart is what, 1.10 - 1.20 meters long? Damn son.

Also, that split flash channel for ignition looks funky.

Probably on the low end of that range. The APFSDS round might actually be a little shorter than the other rounds, since HE/HEAT rounds want to maximize the volume of the projectile and can't be totally buried in the propellant like the APFSDS dart.

But yeah, it's a beast no matter how you measure it. OTOH, I've seen several articles noting that the KE being claimed isn't terribly impressive, only a modest improvement over the current long-barrel 120mm.

KE figures are probably for the penetrator and not the entire projectile. Rheinmetall expected its old 140mm gun to impart 14 megajoules to the penetrator against 23 MJ to the projectile.

I really have no idea how much energy gets left in the sabot. Presumably as little as possible?
