Details: This vehicle is another legacy of Porsche's failed attempts to win the Tiger contracts. Using the early style suspension from the VK4501(P) and with a more balistic design, this was put forward for the Tiger II contract. Again believing that the contract bid would successful, fifty turrets were supplied by Krupp. These were subsequently used on the "Porsche" Tiger II but were critised for their "shot trap" at the turret ring, but as is evident on this hull, for which it was specifically designed, the problem did not occur.

Three prototypes were built of which one was operational and according to authoritative sources this vehicle saw action, albeit briefly, at Kummersdorf in 1945 as part of "Kampfgruppe Kummersdorf" in the remaining weeks of the war.
