The tank destroyer of World War II, German Jagdpanther & Soviet ISU-152

Описание: The Jagdpanther ("hunting Panther"), Sd.Kfz. 173, was a tank destroyer (Jagdpanzer, a self-propelled anti-tank gun) built by Germany during World War II. The Jagdpanther combined the 8.8 cm Pak 43 anti-tank gun, similar to the main gun of the Tiger II, with the armor and suspension of the Panther chassis. It entered service in 1944 and served on the Eastern and Western Fronts. During the last stages of the war, limited German production resulted in small production numbers, shortage of spare parts, and shortened crew training periods of younger operators.
The Jagdpanther was preceded by two attempts at mounting an 8.8 cm gun as a self-propelled anti-tank weapon; Ferdinand - also known as Panzerjäger Tiger (P) - using the ninety-one leftover Porsche-built VK 45.01 (P) chassis from the Tiger tank competition it lost to Henschel in 1942, and the Nashorn on the Geschützwagen III/IV (which used a combination of the Panzer III and Panzer IV components) chassis. Ferdinand proved to be too heavy, and Nashorn lightly armored and under-powered.
A heavy tank destroyer design based on the 8.8 cm Pak 43 gun and the Panther tank chassis was ordered in late 1942. The full-size model by Daimler-Benz was demonstrated in October 1943 before Hitler. MIAG-built prototypes followed in October/November 1943.
Production started in January 1944; in February, Hitler specified the simpler Jagdpanther name instead of its original "8.8 cm Pak 43/3 auf Fahrgestell Panther".
To accommodate the heavier-calibre gun, as on previous Jagdpanzer-style unturreted tank destroyers, the glacis plate and sloped hull sides of the Jagdpanther were extended up into an integral fixed casemate as part of the main hull to provide a roomy interior. The Jagdpanther had side plates armour thickness increased (to 50 mm) to offset the slightly reduced angle of the side plate to provide enough interior space. Lower frontal hull plate was reduced to 60 mm (2.4 in) while upper hull frontal plate was kept at 80 mm (3.1 in). The chassis armour changes were also introduced on the main Panther tank assembly lines with the Panther Ausf. G in spring 1944.
It was armed with the long-barreled 8.8 cm Pak 43/3 L/71 gun, similar to the main gun of the Tiger II ("King Tiger"). The gun was mounted in a central mantlet, giving it a limited traverse of twelve degrees to each side. A single 7.92 mm MG 34 machine gun was in a ball mount on the right side of the front glacis plate. The machine gunner was also the radio operator. The driver sat on the left. The gunner had a rangefinder and a periscope telescopic sight. The periscope – linked to the gun mount – was under an armoured housing on the roof.
The Jagdpanther had a good power-to-weight ratio and a powerful main gun, enabling crews to destroy any type of Allied tank. Based on the established Panther Ausf G chassis, the vehicle encountered few mechanical problems. It was crewed by five: driver, radio operator/machine gunner, commander, gunner, and a loader.

The ISU-152 (Samokhodnaya Ustanovka na baze tanka IS s orudiyem kalibra 152mm, meaning "IS tank based self-propelled installation with 152mm caliber gun") is a Soviet self-propelled gun developed and used during World War II. It was unofficially nicknamed Zveroboy (Russian: Зверобой; "beast killer") in response to several large German tanks and guns coming into service, including Tigers and Panthers. Since the ISU-152's gun was mounted in a casemate, aiming it was awkward, and had to be done by repositioning the entire vehicle using the tracks. Therefore, it was used as mobile artillery to support more mobile infantry and armor attacks. It continued service into the 1970s and was used in several campaigns and countries.
The beginnings of the ISU-152 came on 24 January 1943, when the first prototype of the SU-152 was unveiled. This was a fully enclosed 152mm gun-howitzer on the KV-1S tank chassis. It was designated Объект 236 ("Project 236") . Project 236 was completed in Factory No. 100 in Chelyabinsk, and was tested successfully from 24 January to 7 February 1943. On 14 February the vehicle was adopted and put into production under the KV-14 (кв-14) designation; in April 1943 the designation was changed to SU-152" (СУ-152).
Although the SU-152 was successful in combat, production of the KV-1S tank chassis was ending, which made the modernisation of the vehicle necessary, using the new IS tank chassis. On 25 May 1943 the administration of Factory No. 100 ordered the modernisation of the SU-152, which included increased armour protection and other improvements. Development began in July 1943, under the supervision of Josef Kotin, the chief designer of Soviet heavy tanks, and G. N. Moskvin as the main designer.
