An R.A.C 3.d. document of February 1945 estimated that the British (76.2 mm) QF 17-pounder gun, using armour-piercing discarding sabot shot was theoretically capable of penetrating the front of the Tiger II's turret and nose (lower front hull) at 1,100 and 1,200 yd (1,000 and 1,100 m) respectively although, given the lack of a stated angle ...
Towards the end of World War II, armor plating became still thicker, with tanks such as the Tiger II being fitted with armor over 100 mm (3.9 in) in thickness, as compared to 15 mm (0.59 in) which was more typical in 1939. [3] This prompted the development of a third generation of anti-tank guns, large-caliber pieces in the 57- to 100-mm range. [5]
The Tiger had 100 mm of armor on the front of the hull and turret, while the sides had 80mm of armor. Armor was weakest on the rear of the turret. Americans and British tank forces first encountered the German Tiger I in North Africa, where it outclassed the British Churchills and American M4 Shermans .
However, the prototype hull was never manufactured. The turrets were mounted on the first Tiger II's, which were supposed to be armed with a KwK L/71 gun, like its Henschel counterpart. [2] After the VK 45.01 (P) failed to win the contract, Ferdinand Porsche began looking at ways to improve the design for a future version. Based on the latest ...
A Chinese publication lists 30MnCrNiMo "685" steel as the material used in Chinese rolled armor plates, with a Brinell Hardness of HBW 444-514 (thin) / 429-495 (thick). According to the same publication, older vehicles use a 22SiMn2TiB "616" steel with a hardness of HBS ≤ 219.
The turret had a maximum armor thickness of 279 mm (11.0 in) [4] compared to 185 mm (7.3 in) [5] on that of the German Tiger II, increasing to 305 mm (12.0 in) on the mantlet; and had a traverse speed of 18 degrees per second, taking 20 seconds for a full rotation. The gun was able to elevate 20°+/-10° from horizontal.
An illustration of why sloped armour offers no weight benefit when protecting a certain frontal area. Comparing a vertical slab of armour (left) and a section of 45° sloped armour (right), the horizontal distance through the armour (black arrows) is the same, but the normal thickness of the sloped armour (green arrow) is less.
At 6.24 m (20.5 ft), the length of the KwK 43's barrel was over 1.3 metres longer than of that of the 8.8 cm KwK 36 used for the Tiger I.The cartridge of the KwK 43's shell was also considerably longer (at 82.2 centimetres (32.4 in)) and wider than that of the KwK 36's, meaning that the KwK 43 allows for more room for a heavier propellant charge in its cartridge case than the KwK 36 could.
