Pz. Kpfw. “Panther” (7.5 cm Kw. K. 42 L/70) (Sd. Kfz. 171): Heavy Tank “Panther”

Pz. Kpfw. Panther (7.5 cm Kw. K. 42 L/70) - Sd. Kfz. 171 WW2 Heavy Tank

Introduced in 1942, the “Panther,” a standard medium tank weighing 50 tons in battle order, is designed, by means of sloping armor plates, to present the most difficult angles of attack.

Unlike previous German tanks, its hull and superstructure form a single unit, and the sloping sides and rear of the latter, of 45 mm thickness, overhang the tracks. Its armor plate is of homogeneous machinable quality and, in addition to welding, the main joints have been strengthened by the mortised interlocking of the edges of the plates. The front glacis plate, 85 mm in thickness, is sloped upward at an angle of 33° from the horizontal and the purpose of its construction is to deflect projectiles in such a manner as to clear the gun mantlet. The turret, which has an inner ring diameter of 5 feet, 5 inches, is power traversed but can, in an emergency, be traversed by hand.

The suspension is composed of eight rubber-tired bogie wheels on each side, 33 1/2 inches in diameter. The rear idler has a diameter of 22 1/4 inches. The track is 26 inches wide and has a pitch of 6 inches.

The engine is either the Maybach 60° V-12, HL 210, or the HL 230, the former rated at 642 B.H.P. and the latter 690 B.H.P.

The main armament is a 7.5 cm high-velocity, parallel-bore gun fitted with a double baffle muzzle brake. Some “Panthers,” probably those of early production, are known to have mounted the 7.5 cm Kw. K. 42, while others of more recent production are reported to mount the 7.5 cn Kw. K. 43. The precise differences between the guns are not known. A 7.92 mm MG 34 is coaxially mounted in the turret.

The “Panther” may be equipped to be fully submersible to depths limited by the height of the air-intake pipe—14 feet, 9 inches—but not all are so equipped.

Pz. Jäg. “Panther” für 8.8 cm Pak 43/3 (Sd. Kfz. 173): S.P. Antitank or Assault Gun (Gun Motor Carriage)

Jagdpanther - Pz. Jäg. Panther für 8.8 cm Pak 43/3 (Sd. Kfz. 173)

The standard Model A Panther chassis is used for building this vehicle. The vehicle embodies all of the engineering principles and methods of design accumulated by the Germans up to the time of its production, and is quite effective as an antitank or assault weapon.

The hull and fighting compartment are of all welded construction. The fighting compartment is 45 inches in height at the front and 57 inches at the rear. The length of the roof is 93 inches and the width 72 inches.

The steering mechanism, “one radius steering,” is new. It is unnecessary to engage the transmission in order to turn or traverse the tank through 360 degrees. The use of either steering lever will traverse the tank in a small radius or on the spot. The annulus gear of each of the two epicyclics is driven by the transmission output shaft and is subject to seven speeds forward and one reverse. The sun gears are held stationary on the straightaway by steering brakes. In making a turn, the inside sun gear is released to rotate backward for a sharper turn, the inside sun gear is driven by engagement through a steering clutch with the engine.

The vehicle is armed with the 8.8 cm Pak 43/3 gun in a massive cast steel mantlet which is flexibly mounted in a cast steel ring welded to the front plate. Traverse is 11 degrees. Stowage is provided for 29 rounds of each of two types of ammunition. One M.G. 34 is ball mounted in the front plate to the right. Driver’s vision is by periscope. Fuel capacity is 193 gallons, of which 34 gallons are held in auxiliary.
