Early M3 tanks had the M2 gun, with a 1930 ft/sec muzzle velocity with the APC M61 projectile. Later M3's had the M3 gun, with a 2,030 ft/sec...
No, I think your memory is correct, at least so far as the 75 was considered the HE gun vs the 37mm as the AT gun. At least I've read that...
I believe that was the original intent, for the 37mm to be the anti armor gun with the 75mm shooting HE, but it was quickly realized that the 75mm...
To give a specific example, lets say a M3 faces a PzKpfw III Ausf. J at 1000 yards. Its 75mm gun can penetrate 2.2 (55mm) of homogenous armor, or...
Hunnicutt goes over the combat performance of the M3 pretty well in his book. With the exception of the Long Barreled Mark IV Panzer, they...
The biggest Pro for the M3 is that is was there. It put a 75mm armed AFV at the front line at a point when it was desperately needed. They were...
Here you go. http://www.onwar.com/tanks/ussr/index.htm For example the T-34-76 Model 1940 held 77 rounds of 75mm....
When you say the Mk14 (I think you mean mk15) had a weak warhead, I presume you mean the fuse was weak/unreliable? The Warhead itself was pretty...
Hunnicutt simply calls it the Gyroscopic Stabilizer, I believe it was made by Westinghouse.
I would imagine that was part of the decision as well, plus most M4's did more infantry support then moving combat against enemy tanks, so the...
Hunnicutts Sherman makes particular note of the stabilizer. It did indeed work, at least when properly maintained and the troops were trained in...
Couple of caveats. The 90mm was able to penetrate the Glacis of that particular panther at 600 yards, a better quality plate would do better....
Finally found what I was looking for. Here are comparative tests of the 90mm against actual Panther tanks....
It was issued in very limited quantities to the M26's that saw service at the end of the war. I'm not sure if any got to the M36 tank destroyers....
The normal abcbc round had a small explosive "D" filler, which increased damage with penetration, but could also prematurely detonate and cause...
Basically they were comparable with comparable ammo, i.e. HVAP for the 90mm compares to APDS for the 17dpr, ABCBC compares to the ABCBC. The...
Calculations of immune zones can get really complicated, I mentioned the immune zone of vanguard on the vanguard thread, note I calculated the IZ...
Its not entirely clear. For years Warspite held the record without question, when Tony DiGiulian of the old warships1.com board noticed that...
Fans of Vanguard will complain that such a analysis doesnt take into account the fact that Vanguard has more armored volume then South Dakota, and...
OK, I've calculated the relative vulnerability of the ships belts on facehard at target angles of 10 and 20 degrees. Used the following...
