RARE FILMING - Sturmtiger is the common name of a World War II German assault gun built on the Panzer VI Tiger I chassis and armed with a large naval rocket launcher, the 38 cm Raketen-Werfer RW61 L/5.4. Its primary task was to provide heavy fire support for infantry units fighting in urban areas. The few vehicles produced fought in the Warsaw Uprising, the Battle of the Bulge and the Battle of the Reichswald. The vehicle is also known under the names Tiger-Mörser, Sturmmörser Tiger and Sturmpanzer VI.
Weapons
The main armament was the 380 mm Raketen-Werfer 61 L/5.4, a breech-loading rocket launcher, which fired short-range, rocket-propelled projectiles. These projectiles were roughly 1.5 metres (59 in) long and could either contain a high explosive charge of 125 kilograms (280 lb) or a shaped charge for use against fortifications, which could penetrate up to 2.5 metres (98 in) of reinforced concrete. The stated range of the former was 5,650 metres (6,180 yd). The weight of the complete rounds was 345 to 351 kilograms (760770 lb). A normal charge first accelerated the projectile to 45 metres per second (150 ft/s), the 40 kilograms (88 lb) rocket charge then boosted this to about 250 metres per second (820 ft/s).
The design of the rocket launcher caused some problems, as the hot rocket exhaust could not be vented into the fighting compartment but neither could the barrel withstand the pressure if the gasses were not vented. Therefore a ring of ventilation shafts were put around the barrel which channeled the exhaust and gave the weapon somewhat of a pepperbox appearance.
