Su-101 Uralmash

Su-101 Uralmash
País	Unión Soviética
Papel	Cañón autopropulsado (prototipo)
Diseñado	1944-1945

el Uralmash-1 (Уралмах-1) fue un prototipo soviético de arma autopropulsada desarrollada durante la Segunda Guerra Mundial. Fue un vehículo de combate blindado sin torreta y con seguimiento diseñado por la Oficina de Diseño de Uralmash (UZTM), con sede en Ekaterimburgo, entre otoño de 1944 y la primavera de 1945. Utilizó el chasis del tanque medio T-44 y estaba destinado a reemplazar el SU-100 que a su vez sólo había entrado en servicio con el Ejército Rojo a finales de 1944. Dos prototipos del Uralmash-1 con armamento diferente fueron construidos a principios de 1945, uno con el cañón del tanque D-10 de 100 mm, el otro con la pistola tanque D-25S de 122 mm. Aunque inicialmente se recomendó la producción en masa, el fin de la guerra con Alemania en mayo de 1945 finalmente provocó que el proyecto fuera cancelado debido a la falta de necesidad. Si el Uralmash-1 hubiera entrado en servicio, la variante de 100 mm habría sido designada SU-101 (СУ-101), mientras que la variante de 122 mm habría sido designada SU-102 (СУ-102), de acuerdo con la nomenclatura militar soviética, donde la etiqueta "SU" representaba a Samokhodnaya Ustanovka, o arma autopropulsada.

The “Last Word” in Tank Hunting

el Su-101 (also known as the Uralmash-1) was an experimental Soviet self-propelled gun developed at the very end of WWII. Based on the chassis of the T-44 tank, it was designed to replace the Su-100. Its most radical feature was the rear-mounted casemate, a complete reversal of Soviet design tradition. This layout was intended to solve the “long-nose” problem of previous tank destroyers, where the gun barrel often stuck out so far it would dig into the ground or hit obstacles during maneuvers.

Planta motriz	V-44 diesel (500 hp)
Top Speed	54 km/h (33.5 mph)

A Masterclass in Ballistic Protection

Rear-Mounted Casemate: By moving the fighting compartment to the rear, the designers were able to shorten the overall length of the vehicle significantly. This improved the weight distribution and allowed the heavy 100mm (or 122mm on the Su-102) gun to be mounted with minimal overhang.
Extreme Sloped Armor: The Su-101 featured armor plates sloped at aggressive angles. Its 120mm frontal plate was effectively much thicker against incoming kinetic energy shells, making it nearly invulnerable to the German 88mm PaK 43 from the front.
Engine-Forward Protection: Like the modern Israeli Merkava, the engine was placed at the front. This provided an additional layer of mechanical “armor” for the crew sitting in the rear compartment.
Low Silhouette: Despite the powerful gun, the vehicle stood only 2.1 meters high, making it an exceptionally difficult target to spot and hit in an ambush.

The “Oven” Problem

The Heat Issue: The most significant flaw of the Su-101 was the heat. Because the engine was directly in front of the crew with poor ventilation, the interior temperatures became unbearable during summer testing, sometimes reaching 50°C (122°F).
Cramped Fighting Compartment: The rear-mounted design and low profile left very little room for the crew. Working the large 100mm shells in such a tight space was exhausting and dangerous during rapid fire.
The Su-102 Variant: A second prototype, the Su-102, was built using a massive 122mm D-25S gun. The recoil of this gun proved to be so violent for the light T-44 chassis that it caused structural concerns.
Post-War Fate: By the time the issues were being ironed out, the war was over and the T-54 tank was entering production. The T-54’s rotating turret offered similar firepower with much more versatility, rendering the fixed-casemate Su-101 obsolete. The only surviving prototype is now a star attraction at the **Kubinka Tank Museum**.
