Design

After experiencing fighting in cities, the Heer (army) wanted a self propelled gun made to carry a 21cm howitzer. There was no suitable howitzer so the 38cm Raketenwerfer 61 L/5.4 was selected. The 38cm RW 61 was originally designed to be an anti-submarine weapon.

The recoil was around 40 tons so the Tiger I chassis was selected.

It consumed fuel at the rate of 2 gallons per mile.

Main Armament

The 38cm RW 61 was mounted to the right of the superstructure. Due to the size of the shells, 5' long, a hand operated crane was used to load them into the Sturmtiger. Twelve rounds could be placed in storage racks and one in the barrel. There were rails on the inside roof for moving the rounds from where they were stored to the barrel.

The shell could only be loaded when the barrel was at 0° elevation. There were vents around the gun tube that allowed the exhaust to go forward. It took about 10 minutes to load the 761 lb. shell. The range was around 5,900 meters.

Shell Type Weight Range
HE 716 lb, 761 lb
376 kg
19,685', 6,014 yards, 6,200 yards
6,000 m

There was a hull mounted machine gun located on the right.

Prototype

The first prototype was developed by Alkett and was shown to Hitler on October 20, 1943 at Arys, East Prussia.

Production

Was developed at Henschel's Kassel factory. In August 1944 Alkett converted 18 damaged Tigers.

Brandenburger Eisenwerke produced the superstructure and Alkett converted the Tiger I chassis and completed the vehicle at their Berlin-Spandau plant.
