The Jägdtiger was the most formidable self-propelled antitank gun used by the Germans. It consists of a 12.8 cm PJK 44 (L/55) (less muzzle brake), mounted on a Tiger B chassis.
The hull consists of the normal Tiger B with a builtup superstructure to form a fixed turret. The front plate of the superstructure is 250 mm thick and slopes back at 15° to the vertical. It is made of one solid piece of cast steel armor. The sides of the superstructure are made in one piece with the sloped sides of the fixed turret and, like the Tiger B, are 80 mm thick sloped at 25 degrees. The rear plate of the superstructure is also 80 mm thick with a 10° slope.
The main armament consists of a 12.8 cm PJK 44 set in the center of the front plate of the built-up superstructure. It has a cast, bell-shaped gun shield similar in design to that of the 8.8 cm Kw. K. 43 on the Tiger B. The spherical housing of the gun cradle mounting pivots on a steel ball. The gun is electrically fired and has a vertical sliding breechblock. Separate loading ammunition is used, and the same cartridge case is utilized for armor piercing and high explosive rounds.
With A.P.C. ammunition, penetration of approximately 6 inches of armor at 1,000 yards at 30° is effected; with A.P.C.B.C. ammunition, the penetration is approximately 8 inches.
