"Target: side. Distance: 800 m. Result: penetration, breach size 350 mm by 230 mm.
Target: side. Distance: 1450 m. Result: penetration, breach entrance diameter 110 mm, exit diameter 380 mm. A fragment 700 mm by 92 mm by 82 mm was knocked off. Cracks 220 mm, 200 mm, and 180 mm in length developed."
Some pretty catastrophic spalling going on here. Recall that the T-34-76 had to close in to 500 meters to even have a chance of damaging a Tiger tank, even from the side.
"Target: side. Distance: 1450 meters. Result: penetration, breach diameter 115 mm.
Target: lower front. Distance: 1000 meters. Result: penetration. Entrance diameter 150 mm, exit diameter 160 mm. An armour fragment 230 mm in diameter broke off on the inside. Three cracks, 300 mm long, developed. The welding seam is destroyed."
More catastrophic spalling, this time in the front. More welding seams giving in under pressure. The testers then got optimistic, and moved out to 1500 meters.
"Target: upper front. Distance: 1500 meters. Result: dent 30 mm deep, 120 mm in diameter. Bump on the inside.
Target: lower front. Distance: 1500 meters. Result: the plate cracked from previous impacts by the 85 mm gun. Two pieces broke off: 500 mm by 240 mm and 800 mm by 200 mm."
The Tiger's overhardened armour cracks and falls apart after two hits to the lower front plate. A bit disappointing for a tank that has been made out to be invincible.
"Conclusion: the armour piercing shell can penetrate the side of the Tiger tank, 82 mm thick, from 1500 meters, and the front, 100 mm thick, from 1000 meters."
These are certainly some excellent results. They appear to be confirmed in practice, since a Red Army document on tactics of Tiger combat notes that it can be penetrated from the front at 1000 meters, and from the side at 1450 meters. It is not surprising that an 85 mm gun with similar ballistics was placed first in the SU-85, then in a T-34, to make a dangerous enemy for any German tank.
Now, let's take a look at tests against the Tiger II. The D-5 gun is used in these, mounted on the SU-85 tank destroyer.
"Shot # 22. Target: upper front plate. Distance: 300 m. Result: dent, 200 mm by 125 mm, 50 mm deep (including remains of the shell that welded itself to the armour). A fragment broke off the other side of the armour, 300 mm by 250 mm, 85 mm thick."
For shots from the side, the data is presented in a different report (from which there is only a table in the summary report). From that table, the following conclusions are made:
"The AP shell from the domestic gun D-5-S penetrates:
- the side of the hull from 1350 meters
- the over-track hull from 800 meters
- turret side from 800-1000 meters"
A T-34-85 fought several Tiger IIs from the s.Pz.Abt 501 at Ogledow. There were supposed to be 45 of these new tanks, but only 8 made the 45 km march. Oskin's T-34-85 destroyed 3 of the Tiger IIs in that battle. One of the tanks that was captured at Ogledow intact was the one that served as a test subject in the Tiger II penetration report.
