Bogie wheel skirts: why only on some tanks?


Recommended Posts

I was looking at Bullethead's excellent Tank Page site (people.delphi.com/jtweller/tanks/tanks.htm)

when I started wondering why some (especially older) tanks had skirts over their tread drive assemblies and most didn't. Was it too hard to get useful armor over them? Added too much weight?

Most of the skirted vehicles I have seen were mid to late war vehicles and many of these lost the skirts rapidly once they went into action. Alot of photos will show a tank with some of the skirts missing or bent. Take a look at any tank even today and most have bent fenders. I hope (but doubt) CM will model this "missing" skirt detail. It'd be neat if they had a pool of art for certain vehicles and a randomizor to randomly say tank "X" is missing some skirts and then load the appropriat art for that tank. Same thing with kill rings and vehicle numbers. I suppose they have considered this and either implemented it or discarded it. We shall have to wait and see...

I have no idea why the Allies didn't have skirt armor on many of their tanks. The only "production" version I saw (as opposed to some field modifications) was the prototype Assault Sherman intended for street and other up close and personal combat. That sucker looked MEAN smile.gif

The reason why early tanks didn't have skirts is that their only use is to defend against hollow/shaped charges. These weren't introduced in large volumes until after the invasion of Russia.

Well, wearing skirts in 1940 was the fashion of the day. However, as the war progressed, Allied tankers noticed that the skirt wasn't too becoming of their AFV's, let alone very unconfortable. The Allied tankers decided that it would be fashionably irrisponsible to keep the skirts on their tanks. It is almost as important a liberating event for Allied AFV's in the 1940's as burning your Bra was for women in the 1960's.

Hey Max,

Weren’t you referring to suspension protection armour, not "schürtzen"?

If this is the case Id say you are pretty much correct in your assumptions, especially considering the development of suspension systems demanding more freedom of movement, externally.

In short, it is inefficient and uneconomical in relation to weight. It´s easier to just exchange a destroyed suspension arm.

If Maxm2 was indeed asking about armor specifically to protect the running gear, this sort of protection wasn't practical with the "newer" suspension systems. As Mattias said, developments in suspension systems required more degrees of freedom. The main reason was to prevent buildups of mud which could immobilize the vehicle. Another was that the skirts often fell off because they had to "give" if something hit them or if mud built up. The armor plates on the sides of German tanks were hung, not bolted on for these reasons. Yet another was, of course, weight.

And the final reason... to totally protect the wheels from damage there would have to be a very thick and cumbersome system of armor. Too thick, in fact, to be practical taking into account all the stuff I said above. Adding 20mm of armor wouldn't do jack squat against any form of AT, but that was probably even too heavy for practical use. Uhm... and another problem was that the armor would get in the way of general maintainence and repairs.

My conclusion is that they couldn't effectively protect the running gear from damage, so what was the point of going through all of downsides and NOT achieve the desired end result?

Wow... now that I think about it, there are so many reasons why this didn't happen wink.gif

I have a couple of pics of the Assault Sherman, officially known as T-14. No, it won't ever go into CM as only 2 were ever built, neither of them leaving US soil until one was shipped to Bovington Camp (Tank Museum) after the war. The whole project was at the request of the British, but it failed to impress either the Brits or the US Armies, so the project was scrapped. Having just reread the description, one of the problems cited was the skirt armor made dealing with the tracks difficult wink.gif
