|This page is about the Soviet tank destroyer SU-100Y. For other uses, see SU-100 (Disambiguation).|
The SU-100Y is a premium rank III Soviet tank destroyer with a battle rating of 5.0 (AB) and 4.7 (RB/SB). It was introduced in Update 1.51 "Cold Steel". A rather large profile tank destroyer on-par with the KV-2, but with a much more powerful 130 mm naval cannon, it serves well as a defensive vehicle against an offensive force.
Survivability and armour
- Rolled homogeneous armour
- Cast homogeneous armour (rear hatch)
|Hull|| 60 mm (46°) Front plate

60 mm (49°) Lower glacis
| 60 mm Overall

|60 mm (5-14°)|| 20 mm Front |

|Superstructure|| 60 mm Front
50 mm (1-27°) Gun mantlet
60 + 60 mm Gun shield
|60 mm||60 mm (17°)||20 mm|
- Suspension wheels are 20 mm thick while the tracks are 30 mm thick.
- The protection is only 60 mm thick at its strongest. So it will not absorb any rounds anytime soon. Weapon calibres exceeding 20 mm can pierce the armour, turning SPAAG into a real threat, if close enough. It is a good idea to stay with teammates or remain at distance from the main battle.

- The SU-100Y uses two-piece ammunition, composed of projectiles (yellow) and propellant bags (orange). Both have separate racks.
- Racks disappear after you've fired all shells in the rack.
- Right wall empty: 15 (+15) shells.
Usage in battles
This tank is all about the gun. It defines what being a bonafide tank destroyer is. Bad armour, bad mobility, but amazing firepower. Just park the tank in a position where the SU-100Y will be difficult to flank. That way when the vehicles do fire the gun, it can immediately run and hide while the gun reloads. It can not be emphasized enough, this tank can not let itself get shot at. It just doesn't have the armour. But once ready to let one of the 130 mm shells loose, this tank fears few.
Pros and cons
- The SU-100Y's B-13 cannon is one of the more powerful guns at its rank, able to penetrate ~200 mm of armour at 500 m and enemy tanks rarely bounce the shell
- Astounding 2.35 kg of TNT explosive filler in the PB-46A APHE shell that can reliably knock out tanks with a single shot
- With 5 degrees of gun depression, the SU-100Y has better gun depression than nearly every other Soviet tank destroyer
- The SU-100Y has a very powerful engine, accelerating to its top speed and maintaining it even while going uphill is no problem
- Six-man crew spread out across the vehicle gives this tank a decent chance of surviving a penetrating shell
- Has a research point and Silver Lions boost as a premium vehicle
- Skilled players will recognize the threat a SU-100Y poses - expect to be the centre of the enemy's attention
- This is a huge tank, finding decent cover or a good ambush location is difficult at best
- Sub-par armour - every gun that this tank can face poses a serious threat
- Extremely vulnerable cannon breech and barrel. Problematic as a single hit to them will result in them being in critical condition
- With a terrible manoeuvrability, a mediocre reverse speed and a massive size, dodging enemy fire is nearly impossible
- Even a good crew will take more than 20 seconds to reload the gun
After the failure of the vehicle from testing in the Winter War, the T-100, along with the SMK, fell back into the drawing boards along with other designs that didn't make the cut. But in December 1939, the Red Army requested that Factory No. 185 produce a vehicle based on the failed T-100 chassis. The specifications were for the vehicle to not only operate as a self-propelled gun but in a multitude of roles such as a bridge layer, explosive transporter, and tank recovery.
Development started with the proposal to mount the 152 mm cannon onto the T-100 in order to be able to combat fortifications like the KV-2 with the same armament. The factory manager instead proposed the mounting of a 100 or 130 mm naval gun onto the vehicle instead, and this proposal was accepted on January 8, 1940. The designs, designated T-100-X, was sent to the Izhorskyi factory. At that moment, the T-100-X had a box-shaped fighting compartment with a 130 mm B-13 naval gun. The vehicle had a torsion-bar suspension to stay mobile. Over time, the prototype was redesigned with a modified fighting compartment and such and was resubmitted to the factory for production on February 24, 1940, and redesignated as the SU-100Y. The produced design was tested in March, but the design was dropped from production due to the low demand and the ending of the Winter War. This leaves the SU-100Y with only one prototype ever built. Other methods to either modernize the T-100 or into other variants were made in complementary to the SU-100Y, such as mounting the 152 mm M-10 gun and designating it the T-100-Z. This idea never went past the drawing boards as the success of the KV-1 and KV-2s proved the designs unnecessary. Another idea was to use the T-100 as coastal defence weapon with the 130 mm gun on a turret than a casemate structure, along with three machine guns, like the T-100-Z, this didn't pass the drawing boards.
The SU-100Y prototype was sent to Kubinka in 1940 once the project stopped, however in the Battle of Moscow in 1941, the SU-100Y and its T-100 self-propelled variants SU-14 and SU-14-1 were pressed into service in the Independent Artillery Division for Special Duties. Combat records for these units are not known, but it left the SU-100Y in intact shape, allowing it to be preserved today in the Kubinka Tank Museum.
The SU-100Y heavy SPG was built on a modified chassis of the experimental T-100 tank on which a new cabin with a 130 mm B-13 navy gun had been installed. An experimental model was assembled at Factory #185 in March, 1940. Because combat operations on the USSR-Finnish front had ended, testing the new SPG in combat conditions was impossible. After undergoing tests, the vehicle was sent to the NII BTT research institute testing ground in Kubinka. Further work on this vehicle was abandoned.
