T-90 was armored on par with/more than contemporary NATO MBTs. "Heavy" isn't about size/volume.
Then again, India not signing into more modern T-90MS apparently is only result of the war, and frankly updating Bhishmas to this level can be done through moderate ERA upgrade alone.
But your threat profile is surprising.
There's Korean peninsula, which is the second (if second at all, given that South's previous president literally tried to provoke something) likeliest land conflict for PRC.
Then there's Taiwan, then there are Philippines, then there's Vietnam ... I frankly wonder where did you find peaceful neighborhood.
Heavy MBTs are suitable for neither mountainous terrain, beaches, nor jungles. Heavy MBTs also tend to have a much larger logistical footprint, which isn't ideal if your ground forces require transport via sea or air.T-90 was armored on par with/more than contemporary NATO MBTs.

It's not that bonkers, increasing cartridge volume can easily accomplish this along with telescoped ammo to reduce overall dimensions. It's also how 140mm/130mm guns with a 120mm barrel could perform similarly considering they are designed to use the same breach with massive propellant volume. It is fair here to assume the penetrator is nearly as long as the projectile due to not needing an ERA defeating tip so it could be possible for decent performance matching the latest penetrators but still fall short of newer advanced ammo from larger guns. Again, I never doubted they could make a 105mm have similar armor penetration to the latest rounds but 105 still lacks behind for practically everything else. There is a limit to how long you can make a projectile like HE/MP rounds before they get unstable hence 105mm will always lag behind significantly with filler ammo and gun launched AGTMs due to less space for propellant and payload.To give some perspective of just how bonkers the new 105mm APFSDS is. In the most optimistic scenario, with a penetrator of 750mm and assuming L/D of 30:1, we get this kind of performance:

This is way better than all current in-service APFSDS in 120-125mm caliber. Only not yet in service projectiles compatible with higher powered models of 120-125mm (namely, Russia´s BM69 Vacuum and Germany´s DM83) are somewhat better than this.
In the more conservative scenario, the whole projectile is 750mm long and the penetrator may well measure about 650x21.5mm. The end result is very comparable to the current top performing 120-125mm projectiles such as DM73:View attachment 156612
Either way, we are talking about KE capability of 120-125mm class but in a 105mm caliber. As I said, its just bonkers. Which makes you wonder what kind of propellant technology the Chinese have come up with and the potential to scale up performance if this same thing is upscaled to, lets say, 125mm or larger calibers.
Except we don´t know yet what they did. I´m willing to bet they are using the same cartridge dimensions as regular 105. Then the question becomes about propellant and material pressure tollerances, which is the most interesting part.It's not that bonkers, increasing cartridge volume can easily accomplish this
Yet no one disclosed that part. For it putting no focus on tank-to-tank, its indeed weird that they prioritized getting same of superior performance than current 120mm when it comes to KE but also chose to deprioritize kill capability against anything else. In other words, lower weight being the target, they could have either gone with a larger caliber but much lower pressure ammo (hence enabling a lighter gun) or smaller caliber but with super high pressures to get a lot of kinetic energy and this is what they chose. I guess the Russians would have done the opposite.For a tank that's claimed not to be made for tank on tank, this tank is surprisingly odd.
On that I can agree. This is either a true "medium tank" or may be classified as a new tank class entirely, I like "universal tank": getting MBT-like firepower and survivability with medium/light tank strategic and operational mobility.This design is truly bonkers and in a very confusing way, I am doubting if this is a MBT at all at this point
Not at all.It's it true that because China use a autoloader the round is shorter = less pen
Yes but no, it's not using an autoloader that caused this, it's using this specific design of the Soviet AZ autoloader on T-72/T-90 tanks. Soviet autoloaders have limits on penetrator size due to requiring two-piece ammo(Penetrator in the top piece with a propellant cartridge behind it) although newer iterations of the design can support longer penetrator but still less than western single piece ammo. Western style bustle loader doesn't actually have this problem since they could support NATO standard single piece ammo no issue plus you could install a blowout panel above it for better crew protection.It's it true that because China use a autoloader the round is shorter = less pen
This is basically a modern tank destroyer or assault gun, no? Good for killing tank, possibly weak armor but highly mobile but can't do much of anything else.Yet no one disclosed that part.

I don´t think so because it will be used as the primary offensive maneuver armored asset, ie. a tank. I wouldn´t be surprised at all if the crew is protected to the levels of something like ZTZ99A, in terms of armor.This is basically a modern tank destroyer or assault gun, no?
