And speaking of which, here's the TTB demonstrator awaiting restoration at the National Army and Cavalry Museum. This picture isn't the best angle, but you can see the distinctive narrow, unmanned turret. This only fitted the 'regular' Abrams gun as opposed to the advanced gun on the CATTB, but coupled it to a rotary carousel autoloader located in the turret basket, with a capacity of 44 rounds and a loading rate of 12 rounds per minute. The autoloader was an elegant bit of engineering: an all-hydraulic setup that required minimal electrical power, did not place any reliance at all on spring-loaded components that could wear out, and was successfully test cycled in excess of 66 thousand loading cycles.

The TTB's autoloader takes advantage of the unmanned turret layout to cleverly split the difference between bustle-mounted and basket-mounted designs, with the ammunition carousel placed in the basket with the rounds nose-down and the actual loader mechanism in the bustle. Due to the Abrams' use of semi-combustible cased ammo, the autoloader was required to handle the rounds so gently that *no witness marks* were visible after twenty load/unload cycles -- as absurdly strict as that sounds, it was *achieved*.

You know, I realized something a few weeks back, and the image of the experimental turret above sealed it for me.

You know that RTS game Warzone 2100? The chassis and turret designs are straight up lifted from or "inspired by" WW2, Cold War, and late 80's/90's weapons and vehicles.

The above turret is a dead ringer for the Heavy Cannon Turret in the game.

I would be *shocked* if the Armata turret doesn't use a similar fundamental layout to TTB. The "trick" to the design is that not having to fit human crew members in the turret lets you make the turret not just narrower but *shorter*, which enables the elegant split layout with the ammunition carousel in the turret basket but the loading mechanism in the bustle, loading from the "back edge" of the carousel. With a basket mounted carousel in a traditional manned turret, there's just no way to fit the crew in the turret unless you're loading from the *front* edge of the carousel, but then you pretty much have to put the loading mechanism in the basket as well.

Yep, removing the fragile humans from the turret, remove many restrictions the designers of autoloaders have to deal with.

Well, there's some breach-block adjustments that need made for the plasma igniter, but everything else of the loading mechanics and turret can be kept the same. There's a point the increased pressure demands a new cannon design to withstand it, but you can get a good boost from a drop-in implementation.

I still want to see attempts at hybrid systems, because there's some pretty important complications you can work around by mixing chemical and electromagnetic shell propulsion, mostly regarding manipulating the pressure curve for component wear and combustion optimization. It'd be a ludicrous dick-wave of US overengineering, but it'd be neat!
... the webcomic 6-Commando has the UNA's MBT use such a system...

While far from the worst fictional tank I've ever seen, that pretty much looks like an oversized, clunky WWII turret stuck on an Abrams-ish hull. In particular, it appears that whoever came up with the art does not understand the change in gun mantlet design between WWII tanks and modern tanks.
Well, in this case, WW2 never happened. 6-Commando is a universe where WW1 went on for a few more years and all of Europe became communist. Oh, and the US never became the powerhouse it would have been.

Reminds of the M113 heavy tank TBH.

I mean, thr French are hurting in game.
I doubt it is as bad as the British one

This is turning really ridiculous... Who is next? A german panzer commander posting the data of the Leopard 2A7+ or something like that?

What's next? T14 even though they havnt added it yet? The Chinese? Japanese?
