>Rheinmetall unveiled the new L/51 130mm tank gun currently undergoing company testing. The new weapon provides 50 percent improvement in performance, over the current 120 mm cannon. It is intended for use in a new class of main battle tanks, or as an upgrading of existing tanks. The new 130 mm gun is a precondition for the future tank, known as ‘Main Ground Combat System’ (MGCS) being developed by Germany. MGCS is currently being developed by Germany and France as a future replacement for the Leopard 2 and Leclerc main battle tanks, considering the increasing threat posed by Russian systems such as the Armata (T-14) MBTs

And in the end they will again use broomsticks.
If there's just one fucking thing in the world, just one, that you don't have to worry about slav bro.
It's the German Bundeswehr.

They're re-arming again lads.
>>77257116
I don't know, you still have it in you. It is stll very probable to expect a revitalized german army later in this century, parrying Russia in conventional strength.

Before that she was secretary for women, family and retard affairs.
Well now every military base in Germany has a Kindergarden but they don't have guns anymore.
Guns are bad anyways :^)

That's a nice gun. I'm sure it'll look great on the M1A3.

Rheinmetall guns are used on Abrams as well. And on several other tanks. USA is literally cucked.

I always wondered how much of a meme the abrams armor is,can it bepierced with any current
tank cannon?
>>77256829
do they not know bigger bullets aren't as effective?
A smaller faster projectile is far more effective. That why railguns are so fucking deadly
this is more interesting:

>>77260316
The answer is a definitive maybe. It's hard to know since the export models lack the DU layer which is apparently essential to it not being shit and the domestic models haven't gone up against opposing modern armor.
>>77260316
export monkey models are just RHA so probably not.
murrican models can probably stop a frontal shot but who really knows until there's an actual engagement involving these guns/armor.

>Rheinmetall unveiled the new L/51 130mm tank gun
>Germany had put 140 mm tank guns in Leopard 2s like 25 years ago
This is retarded, even ignoring that it is pointless (Germany won't be fighting T-14s for 40 years when third world shitholes start buying old Russian surplus tanks), Germany had similarly capable guns for decades which were abandoned for the aforementioned reason.
>>77260486
wouldn't mirrors stop that weapon?
The saviors of Europe are back again, look out anglo blood.
>>77262024
nope. technically it's a MASER
https://en.wikipedia.org/wiki/Maser
not sure if it's efficient, but it's interesting.
>>77256829
Europe is ramping up its military complex in general. Germany is currently the world's third biggest exporter of weaponry, France is rapidly increasing their production of military equipment and will overtake Germany next year, for the first time in years Germany will actually start increasing its investment into the military and hire new personnel and so on.
>>77260406
>do they not know bigger bullets aren't as effective?
I am unsure if you are retarded or just pretending to be retarded. Assuming the former let me break it down for you tank shells work a lot like really big bullets, the bigger the shell the more propellant that can be shoved into the case giving it more muzzle energy. The same reason a 7.62 NATO has a higher muzzle energy than a 5.56 NATO is the same reason a 120 mm gun has a higher muzzle energy than a 90 mm gun. However tanks don't fire normal bullets or high explosive shells like artillery, they have different highly specialized munitions for dealing with different threats, the two main munitions for killing tanks are High Explosive Anti-Tank (HEAT) and Armour Piercing Fin Stabilized Discarding Sabots (APFSDS).
>>77262766
HEAT works by having a copper (or other metal like aluminium or tantalum) cone in front of an explosive charge, when the shell hits a target the charge detonates creating a metal jet that can punch through armour, velocity has no impact at all on penetration but the diameter of the metal cone (as well as the cone shape and material) primarily effects penetration. APFSDS works by having a long rod penetrator (LRP) which is effectively a massive metal arrow made of some hard high density metal (generally a depleted uranium or tungsten alloy) being placed in a sabot, so while the sabot is the full bore diameter (eg. 120 mm) the penetrator itself is only a fraction of that diameter (eg. 30 mm). Since the sabot is made of a very light metal or composite the overall projectile is fairly light meaning it can have a very high muzzle velocity (about 1500-1850 m/s depending on gun and shell design) while only losing a small about of its total muzzle energy when the sabot breaks away from the penetrator. So this long ass LRP hits the target and it has a tons of different parameters that effect penetration but the biggest ones are penetrator length, penetrator velocity, and penetrator density. With a higher muzzle energy you can have a much higher velocity, much higher penetrator weight, or slightly higher of each, either way the penetration would be significantly higher.

140mm gun would require an autoloader and a new turret design
the 130mm gun fits in the current leo2 and lec
>>77256829

Pretty worthless desu.
>>77257116
The Weimar republic had 100k soldiers and thats it mostly.... We can do it again, we just have to want it bad enough. Especially if France, Austria and eastern Europe is in on it too for the modern crusades to the middle east.
are tank guns really still relevant? I'm no expert, but aren't modern ATGMs far more effective?
>>77256829
The US is already using the previous Rheinmetall cannon on their tanks.
>>77262285
but the targeting system has to use some sort of laser to guide the high powered maser. Mirrored encasing around a missile/drone could confuse it maybe.
>>77262829
They put 140 mm guns in Leopards 2, both Germany and Switzerland. While they would require an autoloader French, Korean, and Japanese tanks all already have autoloaders, this isn't the early cold war, autoloaders are very reliable.
Either way my main point was that this is redundant, they aren't going to fight any of the tanks that the gun is needed to defeat. As I said sure they might be necessary to defeat Armatas (although I really doubt you would need a new gun to defeat Armatas) but NATO won't actually have to fight Armatas for another 40-50 years when third world shitholes start buying them.

What good will it do to Germans in urban street to street combat?
>>77262829
>an autoloader
no
>a new turret design
yes
the autoloader was not needed, but with the increased weight of the shell would be advisable and when you design a new turret you can also put an autoloader into it.

>>77256829
Russians have 2A83 152 mm smoothbore cannon for the last 30 years at least, with all the needed subsystems, including at least 2 different autoloader solutions.
Germany and Switzerland tried out 140 mm cannons in the '90s, but they gave up on them, since modern fuccbois struggle loading 120 mm shells, let alone massive 140 mm shells.
If Rheinmetal developed an autoloader, now that'd be a change of things.
>>77260316
It is pretty meme
Its armor has deleted uranium which is makes it heavier and doesn't add a huge amount of protection compared to tanks with modern composite like the Leo 2 variants.
An M1A2 compared to a Leo 2A6 with similar protection kits won't have huge differences
>>77260406
You're partly right
Tank armor piercing rounds are sabot - a round that's much smaller in diameter than the tank's cannon. If you have two projectiles with the same mass but one long and thin and the other short and wide, the thin one will be able to apply all of its kinetic force to a smaller area and penetrate more easily than the stubby one. Not to mention the thin one will have less drag.
But a bigger cannon lets you use rounds with bigger cartridges and explosive propellant.
With railguns however, you don't have to worry about propellant and cartridges since the round will just be a ferromagnetic piece of metal propelled by electromagnets across the barrel.
>>77262829
M60 Starships and Sheridans had stubby 152mm cannons. Guys had to take their sweet time, but loaded them just fine.
They were total meme guns though. Many Sheridan commanders got fractured ribs from the recoil
>>77260486
>effective
I'll just slap on a couple fog generators onto the drone, problem solved. The drone's own propellors can spread the thick mist.
>>77261317
The 140mm project had complications, and there's more to a guns performance than the caliber used.
It would still be interesting to see if they had designed something to fit the 140mm, though.
>>77260406
>railguns

>bigger bullets aren't as effective
Bigger rounds are more accurate and have more power, all other things being equal.
>>77258038
I kekt way too long at this.
>>77263546
So, you'll be defending against Russian, not German, tanks next time then?

>Meme weapons.
for now, once you get faster charging/better capacitors and viable power sources they are going to be reality
>Bigger rounds are more accurate and have more power, all other things being equal
something flying 10x faster is going to do more damage then something thats 10x heavier, something traveling at high speed wouldent even need a explosive payload and it would still do more damage
>all that fire, zero explosives
>>77267388
>for now, once you get faster charging/better capacitors and viable power sources they are going to be reality
So yea, meme weapons.
>>77265881
Conventional warfare is dead.
Unless aloha snackbars somehow get a large military infrastructure and start producing their own assets. Or Hillary Clinton starts WWIII. You will never see modern armor vs. armor battles.
These days it's all about of entering a host country, draining its resources and breeding like rabbits. Also guerrilla warfare.
>>77267388
You are well aware that railguns destroy the rails that shoot the projectile, right?
>>77268128
For the time being
>>77258309
arent they all bound by some sort of treaty signed 100 years ago anyways?
>>77256829
>current cannon is 120 mm
>next gen will be a 130 mm
Why not just blow shit up with a 200 mm cannon outright?
>>77268128
The Navy is claiming hundreds of shots from their guns at power levels around what you'd see in a railgun equipped tank. Assuming the rails were relatively cheap and easy to replace it's not a massive deterrent if there's a large enough tactical advantage of the railgun system.
>>77256829
Oh yeah? Who's going to fucking pay for that? Just keep printing more money you morons.
>>77269910
>fit a railgun on a tank

Probably has something to do with ballistics.
Wonderful piece of equipment, just because it is wonderful doesn't mean we need to buy 5000 of them and ruin our economies.
>>77270155
It's not quite tank sized but General Atomics is thinking along those lines.
https://www.youtube.com/watch?v=-xeHfxzjThQ
>>77270248
Even 5000 would not be enough for all the tanks Us has stockpiled.
Anyway, is time for a new project. The Abrams era is over I think.
>>77265974
oh baby, based on the this pic and absolutely zero evidence it looks like it could even be a tapered barrel. The Germans had a 5.5/7.5cm tapered barrel that sent decent sized projectiles screaming. But its probably just a reciprocating system
