Kampfwagenkanone (short: KwK / literal translation de ⇒ en: fighting vehicle cannon) was the designation to any type of tank gun mounted in an armoured fighting vehicle or infantry fighting vehicle of the Nazi-Wehrmcht until 1945. The wording was derived from the German nouns Kampfwagen (fighting vehicle) and Kanone (cannon or gun). However, the present-day designation in German speaking armed forces to this particular weapon system is Panzerkanone (en: tank gun).
Kampfwagenkanonen, developed in Germany, were normally derived from the construction concept of anti tank guns (de: Panzerabwehrkanonen, short Pak). Modifications were used in the anti-aircraft artillery (de: Flakartillerie) as well.
