OOC: This is pretty much me asking you guys what the stats should be for this thing. Sorry for the bad artwork, i'm not a good 3d artist.

IC:

It looks like your average tank...

But it isn't.

HBT-X is an experimental design using three smooth bore guns. Each gun's diameter is 102mm.

OOC: Could you help me come up with stats?

How exactly is the turret handling the weight of 3 cannon?

You'd be surprised what you can accomplish with toilet rolls and sticky-backed plastic :D

I'm sorry, I couldn't help myself. I say that a lot don't I? Anyway, it's a good question. Wouldn't it be a little more realistic with just two guns? Or perhaps, three shorter guns of a smaller calibre?

I guess the same way the Yamato's guns handled the weight of 3 cannons, downscaled to about 1/4th. If that's wrong, then i guess I'll try to figure out another way or abandon this idea.

Two guns are too C & C -esque. And smaller calibre would be too weak.

It's not the weight that'll kill you, it's the torque. Every time the left or right barrels are fired, it'll put the full recoil pressure on the turret drive train. A center-weighted barrel will distribute the load equally across the diameter of the turret and won't deform the drive ring. The other two stress across a chord rather than a diameter. This arrangement would blow off its own turret after a few dozen shots.

Make the outer barrels some kind of self-propelled missle or shell and it might work. Squeezing in a loader might be a chore, of course.

Naval guns are in a much larger carriage and have adequate recoil mechanism. A tank doesn't have room for that.

what about a rotating barrel?

/me hopes that's an adequate solution

Hmmm, if you ask me, the tank would be pointless to have, as the guns probably couldn't penatrate much, but I'll help you out.

First of all, it would way a ton from all of the cannons, and the ammo.

Also, it would be moving very slow, and you'd probably need three autoloaders just to fire the guns, and a complicated computer program to be able to target stuff. You'd also have to have a huge turret to carry the ammo and autoloaders. You'd have a hard time putting a crew inside the turret, so if I were you, I'd stick 'em in the hull. Also, the turret would probably turn very slowly, making it a sitting duck.

With all of this weight, you're not gonna have much room for heavy armor.

And lastly, I still think three barrels is too CnC esque.

Like I said before, its a cool idea, but not really effective in a real battle. Plus It'd be cannon fodder for regular MBTs. I still like the idea, though.

yeah.


bump.

Actually the small round calibre doesn't nessicarily mean a week gun, he could be apeing the 75/105mm or 75/120mm concept of using much much bigger propellant charges than the basic size woudl indicate, you coudl also be facing a variable volume chamber system. How ever multiple main guns won't work that well, any target that woudl require all three barrels would be better dealt with using one larger gun and aiaming the gun independently would be a nightmare.

Chellis for a long time used the Mirca I, a Bradley-ish vehicle with six 20mm cannons, and no ATGM. With enough ammo, that thing was devastating in a town, when it used HE ammo.

Three 102's are pointless, however. The only point, that I could see, would be having three ATGM launchers on one vehicle. ATGMs take fairly long to load, so having three might make it a bit easier...

You could also use small caliber railguns (so as to little recoil, but only if you're FT/a few years in the future) on the side, and a large maingun. The only problem would be that with three guns, its too friggin heavy to haul butt, so you'd sacrifice either armor or speed. You don't really want to sacrifice any of the main four (size inside, speed, armor, and armament). This is a good idea, but it just wouldn't be practical because to produce it well, you'd lose a lot of time and money you oculd have spent on other tanks that are better (ex: WWII Germany's tank program, they made the king tiger, but it was so impractical and costly that they made not a dent on the overall war)

OOC: Points taken. Thanks.

The cancellation of the XHBT project was announced yesterday, after the ministry of defense realized that the design was too impractical for use in combat.
