Tank Busting Armaments... Whats The Best Setup???

15x96mm.

Sure it was developed. It was even deployed a little. But my point is I don't think it was commonly used - it was just too expensive for aircraft guns where most of the rounds would miss the target anyway. Something around 10% or less of aircraft ammo actually hit a target - that's a lot of wasted tungston which was essential to many industrial tools.

The USA had M8 API rounds with tungsten penetrators but switched to a moly-steel penetrator because it was deemed a waste of precious tungsten. And the USA had a lot more avialable tungston than Germany, especially later in the war.

No. the SAE 8620 isn`t stainless. Actually is a Cr-Ni-Mo-Si steel specially designed for superficial hardening by heat treatment.

There is better steel for armour without heat treatment, like SAE 1075, 4340, 4140, but this is really hard when is cemented.

Hmmm, I thought the 8000 series steels were all stainless (at least to a degree). Doesn't substantial chromium and Nickle define stainless????

I cannot view the file - it requires some codec that is not part of Windows Media player.

Yes it does, but you need more than 17 % of cromium and-or more than 15% nickel in the alloy for make it stainless. The 8620 have much less of that.

You need codec Divx. Can be downloaded from:

I think that's some kind of self propelled howitzer. The turret sits far back on the hull. We cannot see the gun length because the gun is pointed twoard the attacker.

BTW: nice film!

If it is cheep and works, use it. I think that volume of fire can help to make up some difference.

[BountyHunter15]

If you ask me, I think the P-51D Mustang with two 20mm cannons would stop tanks dead in their tracks.

[MP-Willow]

Would that be for tanks or for aircraft ?)

[cheddar cheese]

I never even knew 'Stangs were equipped with 20mm's...

[the lancaster kicks ass]

2x20mm wont "stop tanks dead in their tracks", 4x20mm will suffice for "soft" targets, and there are far better ground attack platforms than the P-51, principly the tiffy, with 4x20mm funnily enough........

[cheddar cheese]

Also the Hs-129, with 1x BK 7,5 cannon

[MP-Willow]

P-51s did have 20mm mostlyused by the RAF. The USAAC used 8x0.50s

We have talked about shells and rockets, but the most common way to kill a tank a 100lb bomb!
Or mybe a good artillery volley.

The P-51A1 had 2 x Hispano II's. Most were delivered to the British who used them with 20mm installed. Most, but not all, of those kept by the USAAF after the US entered the war had the 20mm replaced with .50s.

USAAF P-51s had 6x.50cal, not 8, and i can't speak for the US, but the RAF didn't use 100lb bombs, do you mean 1,000lbs??

20mm Hispano's won't kill a tank except for maybe Italian tanks and some very early German tanks. Armored car's and halftracks yes, tanks no!

As an example, the British took a captured Panzer III and set it in a prime location and attacked it repeatedly with Hurc-IIc's. After several thousands of hits something like only 1 was deemed to maybe have killed the tank and two more had disabled it.
