Panzerabwehrkanone, usually referred to as Pak, is the German term for anti-tank gun. Before and during World War II, the German Army produced a series of 13 anti-tank guns which they designated Panzerabwehrkanone, i.e. Pak. In addition, they produced a weapon designated an anti-tank rifle, which is generally considered to be an anti-tank gun; another gun they designated Panzerabwehrwerfer (PAW) the anti-tank launcher.
These weapons ranged from a weight of 229kg (505lb) to a weight of 10160kg (22,400lb). The smallest caliber was 28mm and the largest was 128mm.
Over the six-year course of World War II the armor of the tanks steadily improved, so in order to be effective the size of the projectile had to increase. A larger projectile required a heavier weapon. All of these guns were meant to be towed. The earlier ones were light weight enough to be moved by hand, over short distances, into, and out of, their firing positions. Some variants were only used on tank destroyers, which are self-propelled, like the cannons on tanks.
After each gun, the year of introduction is given.
