Nahverteidigungswaffe

The Nahverteidigungswaffe was a roof mounted, breech-loaded, single shot, multi-purpose, 360° rotating grenade launcher^[1] that could fire a variety of ammunition. It was typically found on German tanks such as the Panzer IV, Panther I, Tiger I, and Tiger II from 1944 until the end of the war and was intended to replace three previous devices: the Nebelwurfgerät, the Minenabwurfvorrichtung, and pistol ports.^[2]

Operation

The Nahverteidigungswaffe was a simple breech-loaded launcher tube oriented at a 50° angle and fitted in a traversable mounting on the turret roof. Unlike the previous externally mounted launchers, it was not exposed to enemy fire, being reloaded from within the vehicle through a hinged breech.

The Nahverteidigungswaffe was designed to mate with the standard 26 millimetres (1 in) Kampfpistole flare gun^[3] and could be sealed by an armored plug when not in use.^[4] Aiming was by periscopes located on the turret and cupola.^[5]

Ammunition

The device could fire the following ammunition:

Schnellnebelkerze 39 smoke grenade for the purpose of concealment
Rauchsichtzeichen Orange 350 smoke signal for identification to friendly aircraft
Leuchtgeschoss R flare
Sprenggranatpatrone 326 Lp anti-personnel explosive to defend the vehicle against infantry attack^[6]^[7]^[8]^[9]

The Sprenggranatpatrone 326 Lp had a range of 7 to 10 meters (23 to 33 ft) with a blast point of 0.5 to 2 meters (2 to 7 ft) above the ground. It splintered to a circumferential distance of 100 meters (328 ft) after an initial delay time of one second.^[10] All turret hatches and openings were to be closed when this round was fired.^[11]

Deployment

The Nahverteidigungswaffe was first mounted in March 1944 on the Panther tank.^[12] It was equipped on a variety of late-war vehicles, including the Sturmtiger and the Maus tank.
