Weren't some armies talking about potentially switching to telescoped darts a while back?

If that becomes technically feasible that would be another mark against a dual autoloader system.
The current Western APFSDS rounds can be considered semi-telescoped ammo. All of them have the projectile expand into the propellant case.

French wanted to go full telescopic to accommodate 140 mm ammo. I don't think anyone will adopt their solution though. German semi-telescopic 130 mm will likely become the global standard. It is just common sense as it is an upgrade to the current paradigm.

I wonder if this obession with longer kinetic penetrators is really worth it. Since tank on tank battle is so exceedingly rare in comparison to atgm/UAV kills. Having a tank that's 'good enough' for general purpose via HE shells and also being able to fire NLOS missiles against other tanks seems to be a better approach, with sensor suite being such a focus now why bother risking the tank in a direct cannon on cannon battle?
I have a similar opinion too. Even on this forum, I advocated for cheaper tanks that are optimized for infantry support and that have measures against UAV. Tank vs tank is rare and can be left to the ATGM units. If APFSDS capability is still wanted, it can be kept in a missile form. Such missiles were being researched 25 years ago.

Only older Leopard 2 models have ammo in the hull, near the driver, but in newer variants everything is inside the bustle as it's much safer for the crew. 99A's design philosophy comes straight from T-72 and so does it's autloader even if slightly improved.
All do.

It's almost* impossible to fit enough 120-130mm ammo for exploitation in just a bustle alone. Ammo requirement is typically calculated at the expected number of rounds/engagements(adjusted for round effect), to have enough separate engagements.
What is possible is to not load anything other than ready-use ammunition (meaning bustle for most western tanks and carousel for t-64 group), if you don't plan to do penetration, and can reliably return to rearm after a single engagement.


*Abrams is almost there, but still not enough, even for minimal requirement(and 120mm abrams significantly lowered offensive requirement compared to 105). There was a single obscure Russian prototype(obj. 640) - which in fact did fit enough, but at the expense of the high vulnerability of the bustle even from the front angles.
All others go for a mix - i.e. ready rack sufficient for tactical situations(20-30), secondary storage elsewhere.

Most of the ammo is still in the hull for NATO tanks except for the M1 Abrams. This is partially why Germans are investing a lot in insensitive propellants and explosives. The DM-73's propellant is seriously impressive with its total insensitivity to even shaped charge jets for example. The biggest problem for Russian tanks is that they store ammo all over the place. Which makes it hard to not hit them.

This is really bad. The only worse one is likely the Challenger 2. With the recent T-90s, they tidied it up a bit, even moving some to a blow-off compartment in the bustle.

But it is still not optimal. I would not want any ammo in the fighting compartment if possible. Only the Abrams and the Type-15 can fit that requirement as of 2023. I think the time to replace the Type-99A has come.



IMO Abrams is a very good tank with the exceptions of its weight and fuel consumption. However I still find it funny how Americans on the internet were defending its every design feature like a religion and then we learned it will become a tank with an unmanned turret, autoloader, and a diesel engine. Most religiously defended features were discarded by the US Army.
It's the Apple effect. If Apple does something, it's considered innovative and becomes the trend. It just depends how well a company or country is about to brainwash its citizens or customers.

We all knew this was the trends tanks were going to go. It was just a matter of technology maturing.

multiple sources online claim that the type 99A's frontal armor is equivalent to 1000mm. the Abrams only has 700mm.
this plausible at all?

The 99A uses ERA on top of its composites. It may be possible for the first hit through an ERA block that the 99A can offer better protection but worse after that. The Abrams has alot of room in its turret for very thick composites that cover more of the frontal arc than the 99A. Its possible that the 99A has more protection but with only full coverage by its composite armor if its pointed directly at the enemy. The upper frontal armor of the Abrams is actually very thin but sloped at an extreme angle. I have no idea what the currently models have but older declassified documents showed that it was only 38.1mm thick. You can tell its relatively thin by looking at pictures with the drivers hatch open. Although the lower frontal armor has plenty of room for a thick composite block. The hull armor is still probably weaker than its turret armor though due to having less space.

The overall protection of the Abrams is probably better, but id wager the 99A probably has more frontal protection to it's upper frontal armor (The lower frontal armor is thought to be pretty weak) and frontal turret. If you look at the shape of the 99A's frontal armor from the top it should provide better armor coverage against high angle attacks due to the frontal turret shape and the coverage by ERA when looking at the 99A from a 45 degree top down angle. But who knows. I'm just some random guy on the internet guessing about tanks.
