Tiger I
In September 1943 plans were made for Krupp to fabricate new Tiger I armored hulls for the "Sturmtiger". The Tiger I hulls were to be sent to Henschel for chassis assembly and then to Alkett where the superstructures would be mounted. The first prototype was ready and presented to Adolf Hitler in October 1943. Delivery of the first hulls would occur in December 1943, with the first three "Sturmtiger" completed by Alkett by 20 February 1944.
