Armour thickness on tanks


Europa

Recommended Posts

I'm wondering after playing germans alot:

Why are there no tanks with very armoured turrets on flimsy hulls? I might be damaged due to playing CMAK instead of dying in Normandy, but I get the impression that a small number of such vehicles would be useful in hulldown positions.

Weight at the front of the turret is at a premium in a tank, because this is where most of the weight for the main gun sits.

So if you have a big gun and a lot of armor at the front of the turret, you have to put a heavy counterweight at the back of the turret to counterbalance it.

There's only so much weight you can add to the turret before it starts creating structural and/or balance problems. For example, an overly heavy turret creates higher center of gravity, can create problems with turret traverse mechanisms (too much weight to rotate), or with the overall weight balance of the tank.

This is why you see tanks like the PZIV, which starts the war with a short 75 and relatively balanced armor protection between the hull and turret. As it gets upgunned and uparmored, though, pretty soon they hit the upper limit for the amount of weight they can add to the front of the turret, and have to choose between a bigger gun, or more armor. Most of the time, designers chose the bigger gun.

The problem is also to come up with a turret rotation mechnism which can move the turret if the tank is standing on a slope. E.g. the KV-2 couldn't.

The root of the problem is that the turret ring mechanism is expensive (mechanism, bearings etc), and tank planners for too long were building too narrow turret rings which then limited upgradability.

I disagree with the original poster's thesis that strong-turret tanks are actually useful. A tank always meant for moving and attacking first. Also, if the thick turret would be sufficient, then the Germans would have put such a large plate on their tank hunters.

I'm reminded of the awful problems the M10 TD had with its unbalanced turret. Horribly slow rotation on any kind of a slope. that's why with later and later models the rear counterweight kept getting bigger and bigger til the final 'duck bill' counterweight projected far out from the turret.

This is usually the point where one hopes for an 'unbalanced turret' feature in the new game engine, but I doubt there wil be any M10 TDs running around in CMx2:Space Lobsters.

Exactly. This was the "problem" with the Matilda. It was an amazing tank for its time, but it was stuck the the 2-pdr because its turret ring was too small to withstand a heavier gun.

Actually, I'm pretty sure they had unbalanced load indicators in the '40s.

But what good would it do? This is a design issue, not something that occasionally happens when you put a few too many AP rounds on one side of the turret -- a heavy turret front makes the turret unbalanced *all the time*. An unbalanced load light would just be a rather expensive and complicated running light. . .

An 'unbalance indicator' light would be kind'a redundant if the light comes on only when the turret rotation slows to a crawl - something that would be readily apparent. An experienced tank driver would make a point of avoiding eleven degree can angles when he comes to a stop! Concerns like these were why it often took awhile for a tank to get into a proper hull-down defensive position.

My clothes washer gets them all the time, so the mechanism shouldn't be too expensive.

Perhaps you should add a car battery at the same time as your clothes to avoid the imbalance in the first place. </font>
