turret front by 6 rounds. Hit #13 was moved. '?' is unknown hit. Other locations were moved very slightly to compensate for perspective. At the point of the photograph the weld between the upper hull and lower has burst open after taking 8 heavy hits along it. A piece of the lower hull is missing as three 100mm AP shots and a 122mm AP shot struck near each other in a cluster.
Impacts of 3-4 armor-piercing or high-explosive fragmentation shells from 152, 122, or 100 mm artillery pieces caused cracks, spalling and destruction of the weld seams in the tank's 100-190 mm thick frontal armor plates at ranges of 500-1000 meters. The impacts disrupted the operation of the transmission and took the tank out of service as an irrevocable loss.
Armor-piercing projectiles from the BS-3 (100 mm) and A-19 (122 mm) gun completely penetrated when impacting the edges or joints of the "Tiger-B" tank's front hull plates at ranges of 500-600 meters.
#22 85 mm armor-piercing projectiles from the D-5 and S-53 gun failed to penetrate the tank's front hull plates or cause any structural damage at distances of 300 meters.
What looks like a key to the diagram is in the lower part of the graphic. The lowest line "152/122" may be High Explosive (HE) shells. The third column of the key diagram represents penetrating AP hits. The fourth column of the diagram key has the word 'He' in the label meaning 'not' - thus not penetrated. The graphic of the shell locations was probably produced by some author for their book or web page at a much later date.
The accuracy of the turret diagram is questionable. I rearranged some of the markers here to reflect this text from the archived Russian Battlefield and other sites:
Armor-piercing projectiles from the BS-3 (100 mm) and A-19 (122 mm) gun completely penetrated the "Tiger-B" tank's front turret plate at ranges of 1000-1500 meters. The front armor of the turret. Penetration #23 was made by a 100 mm armor-piercing projectile*. (maybe not) Penetration #25 was made by an 88mm armor-piercing projectile that went completely through the turret at a range of 400 meters.
However another report states that penetrations #21,#23,#24,#25,#36 were all 88mm/L71 APHE at 400m. One 88mm APHE that penetrated the turret produced an exit hole on the back plate of the turret.
#21 88mm/L71 on hull from 400m produced a dent 360mm by 130mm 90mm deep. Knocked out 510mm by 160mm fragment on the inside.
