Su-101 Uralmash
Land	Sovjetunionen
Roll	Självgående pistol (prototyp)
designad	1944-1945

Den Uralmash-1 (Уралмаш-1) var en sovjetisk prototyp självgående kanon som utvecklades under andra världskriget. Det var ett tornlöst, bandgående pansarfordon konstruerat av Jekaterinburg-baserade Uralmash design bureau (UZTM) mellan hösten 1944 och våren 1945. Den använde chassit på T-44 medeltanken och var avsedd att ersätta SU-100 som själv bara hade gått i tjänst med Röda armén i slutet av 1944. Två prototyper av Uralmash-1 med olika beväpning byggdes i början av 1945, en med 100 mm D-10 tankpistol, den andra med 122 mm D-25S tankpistol. Medan massproduktion ursprungligen rekommenderades, orsakade slutet av kriget med Tyskland i maj 1945 så småningom att projektet avbröts på grund av bristande nödvändighet. Om Uralmash-1 hade tagits i bruk skulle 100 mm-varianten ha betecknats SU-101 (СУ-101) medan 122 mm-varianten skulle ha betecknats SU-102 (СУ-102), i enlighet med sovjetisk militärnomenklatur, där "SU"-etiketten stod för Samokhodnaya Ustanovka, eller självgående pistol.

The “Last Word” in Tank Hunting

Den 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.

Kraftverk	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**.
