Definition:
The 8.8 cm KwK 36 was a German 88-millimeter-caliber tank gun used during World War II, primarily mounted on early variants of the Panzerkampfwagen VI Tiger I heavy tank.
Overview:
Developed by Krupp and introduced in 1942, the 8.8 cm KwK 36 L/56 (KwK: Kampfwagenkanone – "vehicle-mounted cannon") served as the main armament of the Tiger I tank. It was derived from the well-known 8.8 cm Flak 18/36/37/41 anti-aircraft gun but modified for use in armored fighting vehicles. The KwK 36 was designed for anti-tank and direct fire support roles, offering high muzzle velocity and excellent armor-penetration capabilities, which made it effective against most Allied tanks at typical engagement ranges during its operational period.
Etymology/Origin:
The designation "8.8 cm KwK 36" breaks down as follows: "8.8 cm" refers to the bore diameter of 88 millimeters; "KwK" stands for Kampfwagenkanone, meaning "fighting vehicle cannon"; and "36" indicates the model year of design approval (1936), although actual deployment occurred later. The gun was adapted from the Flak 36 anti-aircraft artillery system to meet the German Army's need for a powerful tank-mounted weapon capable of defeating heavily armored enemy vehicles.
Characteristics:
- Caliber: 88 mm (8.8 cm)
- Barrel length: 4.86 meters (L/56 – 56 calibers long)
- Ammunition: Separate-loading, fixed-type with charge and projectile
- Rate of fire: Approximately 10–12 rounds per minute
- Muzzle velocity: ~773 m/s (PzGr. 39 armor-piercing round)
- Effective range: Over 2,000 meters against armored targets
- Traverse: Limited by turret; full 360° possible through hull rotation
- Mounting: Central mounting in the turret of the Tiger I
The KwK 36 utilized advanced optics and a well-balanced recoil system, allowing accurate fire from a stabilized platform. Its high-velocity rounds could penetrate over 100 mm of rolled homogeneous armor at 1,000 meters, providing significant battlefield superiority during early deployments.
