The Tiger (P) (commonly known as Porsche Tiger, while its official designation was VK 4501(P)) was an unsuccessful German heavy tank prototype that lost against what would become the successful Henschel Tiger I tank.
Unlike the Henschel design's mid-hull mounting for the turret, the VK 45.01 (P) had its Krupp-designed turret mounted at the front. The turret, which mounted the 8.8 cm KwK 36 and a 7.92 mm MG 34 coaxial machine gun, was essentially the same Krupp design also used for Henschel's contract-winning VK45.01(H) prototype design. The first eight turrets produced had lower sides and a flat roof with raised centre section to allow the gun to be depressed through a larger arc.
