Su-101 Uralmash

Su-101 Uralmash
Zemlja	Sovjetski Savez
Ulogu	Samohodni pištolj (prototip)
Dizajniran	1944-1945

Čaj Uralmash-1 (Uralmas-1) je bio sovjetski prototip samohodnog topa razvijen tokom Drugog svetskog rata. To je bio bez kupole, gusjeničar oklopno borbeno vozilo dizajniran od strane Jekaterinburga sa sedištem u Uralmash dizajn biro (UZTM) između jeseni 1944. i proleća 1945. Koristio je šasiju srednjeg tenka T-44 i trebalo je da zameni SU-100 koji je i sam ušao u službu sa Crvenom armijom krajem 1944. godine. Dva prototipa Uralmash-1 sa različitim naoružanjem izgrađena su početkom 1945. godine, jedan sa 100 mm D-10 tenkovskim topom, a drugi sa 122 mm D-25S tenkovskim topom. Dok je masovna proizvodnja prvobitno preporučena, kraj rata sa Nemačkom u maju 1945. godine na kraju je doveo do otkazivanja projekta zbog nedostatka potrebe. Da je Uralmaš-1 ušao u službu, varijanta od 100 mm bi bila označena kao SU-101 (SU-101), dok bi varijanta od 122 mm bila označena kao SU-102 (SU-102), u skladu sa sovjetskom vojnom nomenklaturom, gde je oznaka "SU" označavala Samohodnaja Ustanovka, ili samohodni top.

The “Last Word” in Tank Hunting

Čaj 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.

Attribute	Technical Specification (Su-101)
Ulogu	Self-Propelled Gun / Tank Destroyer
Posada	4 (Commander, Gunner, Loader, Driver)
First Prototype	April 1945
Glavno naoružanje	100 mm D-10S gun
Sekundarno naoružanje	12.7 mm DShK anti-aircraft machine gun
Frontal Armor	120 mm (sloped at 55 degrees)
Powerplant	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**.
