Despite the first prototype being presented to Hitler in October 1943, production was not requested until April 1944. The first three conversions, using rebuilt Tiger I chassis, were complete by August 1944 with the rest of the nineteen produced being finished by January 1945. The type saw action during the Warsaw uprising and later during the battle for the bridge at Remagen, Germany. Captured by Soviet forces in the Elbe area in April 1945, this late model Sturmtiger is one of only two survivors and has recently been repainted into an accurate colour scheme and markings. It is on display in Hall 11 of the Patriot Museum Complex. Park Patriot, Kubinka, Moscow Oblast, Russia.
