China has superior 125mm guns. Reminder that Rheinmetall proposed a 130mm gun for the next generation western tank because the 120mm is inferior to Chinese 125mm guns. And even if the west use the 130mm guns, they would still lose against Chinese super 155mm guns on tanks.

You're more than good enough for my standards, Apu
>Is 120mm the endgame? No. Tank gun calibers will likely increase in the next few decades with the EU's MGCS and the US army DLP.
Bentley Torres
Rheinmetall had a functional 140mm ready in the 80s when the 120mm with 44 caliber length was standard. Then Cold War ended and there were no real threads that justified the expenses of switching to a new gun AND new ammo. So when Rheinmetall brought the 120mm L/55 they recycled lots of components that had been developed for the 140mm. Nowadays with emerging chinks and a somewhat completely developed 120mm range the change to a new caliber seems interesting especially considering emerging threads from russia and china. Fact is the west will be foced to upgrade and a 130mm would be more expensive. But it would be a much bigger upgrade with lots of room for further development than the 120mm. But dont ask me why they seemilngly abandoned the 140mm idea. Perhaps better metallurgy made it possible to stay 10mm smaller. >China has superior 125mm guns China has the same medium pressure shit the russians have with the very same limitations. A bigger tank gun is much more than a larger barrel diameter you fucking chink. Also TIANANMEN SQUARE WINNIE THE POOH LIBERTY FREEDOM OF SPEECH!

>China has the same medium pressure shit the russians have with the very same limitations. A bigger tank gun is much more than a larger barrel diameter you fucking chink. This is what Americans want others to believe because they clearly have an inferior cannon. Protips, China leads in railgun innovation not to mention electrochemical thermal guns.
But how much bigger can they get? What comes after 130 and 140mm? 155mm?
Jordan Davis
No.
Rheinmetal are working on a two stage process for tank guns. The L55A1 is now been developed which is a smoothbore L55 gun with a high pressure breach allowing 20% greater perfromance over the current L55 on Leopard. Challenger 2 looks set to be the first tank to get this as it has a similar footprint to the existing L55 (CR2 will be getting a turret redesign)
After that Rheinmetal have a 130mm gun which uses this new breach technology and pairs it with a larger calibre. There are currently no tanks planned with this gun as it's still maybe a decade away but it should improve performance by up to 50% over the existing 120mm L44 on Abrams.
Russia uses a 125mm gun in T14 but plans to use a 152mm gun at some point in the future.
Austin Ward
120mm is the limit for manual loading. If we venture in the 130mm or 155mm range, tanks will probably need an autoloader.

There was a time when people said that about 17 pounder guns in tanks.
Jeremiah Watson
17 pounder cartridges are similar in length to 105mm and 120mm cartridges.
Ethan Hernandez
and about half as wide and a fair bit lighter.
Carter Hughes
17 pounder rounds were smaller than others of the time period, it sounds like you are repeating a zombied myth.
Jordan Long
>China has the same medium pressure shit the russians have with the very same limitations.
Patently false.
China's 125mm guns are the upscale of their own 120mm guns used by the earlier PTZ-89 120mm tank destroyer. The ZPT-98A is a 52 caliber 125mm gun that has higher muzzle velocity and chamber pressure than the 48 caliber 2A46M used by Russian tanks.
>China's 125mm guns are the upscale of their own 120mm guns used by the earlier PTZ-89 120mm tank destroyer No. The PTZ-89 used an indigenous copy of the L44, while the ZPT98 is similar to the Russian smoothbore, firing the same 2-part ammunition.
Jeremiah Baker
Same 2 part ammunition, but the penetrator rods are longer than comparable Russian ammo and the gun itself has highe chamber pressure than the 2A46M
Autoloaders already exist. What are the limits to caliber? If the next guns are 140, is it an eternal increase to 203mm and 16" or does caliber cap or begin reducing eventually?
Benjamin Lopez
>China's copy of a Russian 125mm gun that fires two piece ammunition is actually just an upscale of China's copy of a German 120mm gun that fires single piece ammunition
James Ward
comparable ammo meaning what Russia exported to China
Levi Powell
There is more to guns than just ammo design.
A AR wont suddenly become an AK when it gets rechambered for 7.62x39.
Liam Long
Russia never exported tanks and tank ammo to China, simply because of the Sino-Soviet Split.
Jose Robinson
Correct, China's copy of a 125mm Russian gun wouldn't become China's copy of a 120mm German gun if you rechambered it for 120mm single piece ammunition.
Jack Brown

>What are the limits to caliber? Ammo Storage, Ammo handling and logistical burden per shell, recoil mitigation and turret ring sizes
>does caliber cap or begin reducing eventually You have a gun big enough to do the job effectively and a little bigger just to be safe Larger guns suit HEAT better but composite armour has hindered that - hence the focus on high velocity discarding sabot rounds The size of Sabot rounds is limited mainly by ammo storage and gun chamber pressure If you increase the volume of the chamber for a bigger round you have weakened the chamber walls, making a higher risk of chamber rupture This is offset by increased mass reinforcing the chamber walls Caliber increases lead to exponential weight run aways and you logistics then restricts that that

You faggots post this like it's some kind of ward against Chinese boogeymen. Also, you're not supposed to take the bait, retards.
