1 Background£º
Tiger I is the common name of a German heavy tank developed in 1942 and used in World War II. The final official German designation was Panzerkampfwagen Tiger Ausf. E, often shortened to Tiger. It was an answer to the unexpectedly formidable Soviet armour encountered in the initial months of Operation Barbarossa, particularly the T-34 and the KV-1. The Tiger I design gave the Wehrmacht its first tank mounting the 88 mm gun, which had previously demonstrated its effectiveness against both air and ground targets. (Source )

The 8.8 cm KwK 36 L/56 was an adaptation of the famous 8.8 cm Flak 36, which was a development of the Flugzeugabwehrkanone Model 18 (Flak 18). In informal German use, this gun was universally known as the Acht-acht, a contraction of Acht-komma-acht Zentimeter (8.8 cm = 88 mm), and was first used in combat by the Condor Legion, in Spain, where it earned the reputation of being an excellent anti-aircraft gun as well as a tank killer. This capacity would be confirmed during the French campaign in 1940, and most spectacularly in the hands of Rommel's Afrika Korps in North Africa. The Flak 36 was essentially a Flak 18 mounted in three sections, making possible to change the part of the barrel that suffered most attrition from the high-velocity rounds. By the time the Wehrmacht was heavily committed in Russia, it proved to be the only gun in the German inventory capable to destroy the new T-34 and KV-2 Russian tanks at longer ranges.

At a Panzerkomission meeting on 14 July 1942, the subject of Tiger armament was discussed again, and it was verified that the ability to penetrate 100mm of armor, under the requiderd conditions, was also achieved by the 88mm KwK 36 L/56, therefore conversion to the 75mm KwK 42 L/70 was no longer necessary, and conversion to the 88mm KwK L/71 would ocurr at the end of the same year. This decision resulted in the entire production run of the Tiger being outfitted with turrets mounting the 88mm KwK 36 L/56. As a matter of fact, this increase of the penetration abilities of the 88mm KwK 36 L/56 resulted exclusively from changes to the design of the armor piercing (APCBC) ammunition. Greater armor penetration was achieved by decreasing the size of the explosive filler cavity inside the shell, which also increased the weight to 10.2 kilograms (JENTZ, Thomas L.; Germany's TIGER Tanks - Tiger I and II: Combat Tactics; op. cit.).


The Tiger I, with its 88 KwK 36 L/56 gun, coupled with superior optics, could accurately hit targets at ranges the enemy could not even aim at.

Please note that 88 mm KwK 36 L/56 means: The diameter of the bore (caliber) of this gun is 88 mm; this is a Tank Gun (Kampfwagenkanone); that the year the development of this gun was finalized was 1936; and that the length of the gun equals 56 times the diameter of the bore (caliber) of the same gun. This measurement was done from the rear face of the breech to the end of the muzzle, not counting the muzzle brake. This was the main gun installed on the Tiger I.
