90mm T15E1 Gun Data:
70 Calibers

Penetration:

T43 AP Shot (APBC-T; 3,200 ft/sec)
132mm @ 30 degree angle @ 500 yds
127mm @ 30 degree angle @ 1000 yds
124mm @ 30 degree angle @ 1500 yds
122mm @ 30 degree angle @ 2000 yds

T44 HVAP Shot (APCR-T; 3,750 ft/sec)
244mm @ 30 degree angle @ 500 yds
221mm @ 30 degree angle @ 1000 yds
196mm @ 30 degree angle @ 1500 yds
173mm @ 30 degree angle @ 2000 yds

If these number are right. Then the gun on the normal M26 was more powerfull but I thought the T15E1 was suppose to me a better gun with the longer barrell and all.

The gun on the normal Pershing was; from Hunnicutt's Pershing:

Ok. So do you now how they come with penetration numbers for the game? I under stand the Armor ratings. If I did it right, the modified Super Pershing should have frontal armor of 18 for the hull front and 19 for the turret front.

I was investigating the Super Pershing myself today and there are some fairly consistent penetration values for the 90mm T15E1 L73 gun, but the value seem to be a bit fantastic. Perhaps people could comment a bit?

330mm @ 30 degree angle @ 100 yds
240mm @ 30 degree angle @ 1000 yds
Panther Hull @ 2600 yds

The 90mm L73 T15E1 gun was an attempt to provide the same kind of performance as the German 8.8cm PAK 43 anti-tank gun. Like the German gun in addition to the longer barrel the gun fired ammunition with a larger propelling charge. Muzzle velocity firing the T30E16 projectile increased from 3,350fps to 3,750 and T33 from 2,800fps to 3,200fps, increasing the range at which a Panther hull front could be penetrated to 2,600 yards! Originally the T15 used one-piece ammunition but at 50-inches long it was too bulky to handle in a tank turret so a redesign was undertaken to employ 2-piece seperately loaded rounds, which became the T15E2 to be mounted on the Heavy Tank T26E4. Even with 2-piece ammunition the cartridge case extended past the turret ring during loading which could cause problems at anything other than level elevation.

Here is the penetration according to a classified US Army document dated June 1945:

Here's the armour thickness they could penetrate at 30 degrees:




ps. Panther front hull is 85mm, at 55 deg it would be 148mm
