Player Opinion
Pros and Cons
Pros:
- Fast and agile
- Low profile
- The top gun aims very quickly
- The armor can bounce some shots, especially from lower tiers.
- Exceptional rate of fire.
Cons:
- Low penetration and damage in comparison to other Tier 8 TD guns
- The armor will not stand up to high penetration guns
- Atrocious gun depression. You cannot hit a heavy tank's lower glacis plate if it gets too close.
- Very prone to artillery damage
- Lowest HP of all tier 8 TD's
Performance
The limited gun depression combined with the relatively low damage output makes it very difficult to play well, and the very expensive ammunition and (for a TD) relatively high repair cost makes it almost impossible to make a profit on loss. It is easily possible to lose money on a win if a number of shots miss or fail to penetrate.
Due to these limitations it is recommended to stay hidden in the second line instead of pushing forward in a too aggressive way and risking to be left alone by your team members. Although your the gun has a very good DPM, You do not have the armour and HP to be an assault tank. Furthermore, a player should use the guns accuracy, rate of fire and quite fast aiming time in order to participate in the combat action at ranges between 200 and 400 meters distance, benefiting from camouflage provided by crew skill and/or bushes. This tank may seem to be very lacking compared to its tier 8 counterparts but using patience, camouflage, and proper positioning this TD can prove to be as useful as any other tank at its tier.
Crew Skills
Sixth Sense and Camouflage are essentials for this tank. Due to the low durability and alpha damage this tank relies on its camouflage and rate of fire. A good camouflage crew, and a commander with Sixth Sense could potentially save your life several times in one battle. The skills or perks beyond this are not as essential and can be chosen on player opinion of performance.
Early Research
- Nothing carries over from the SU-100M1.
- You can immediately research either gun or the first engine.
- If you want to use the 122 mm D-25 mod. 1944 Gun, research it first. This step is optional.
- Next, research the V-2-54 Engine.
- Now, research the 100 mm D-54S Gun.
- Next, research the V-54-6 Engine.
- Now, research the SU-101M Suspension.
- Finally, research the R113 Radio.
- If you chose not to research the 122 mm D-25 mod. 1944 Gun earlier, do so now.

Development History
In the fall of 1944 UZTM (Ural Heavy Machinery Plant) began the production of a new medium SAU (self-propelled artillery unit) the SU-100, armed with the powerful 100mm D-10 gun. The machine possessed good maneuverability for its class, and with 75 mm of sloped armour had very good protection for its weight. In comparison, much heavier assault gun SU-152 was also protected by 75 mm of frontal armor.
Nevertheless, Soviet self-propelled guns had a number of essential deficiencies, characteristic of any self-propelled gun with a forward fighting compartment arrangement. The adoption of ever longer barreled guns increased the overall dimension of the SPG lengthwise. The result of mounting a long overhanging gun low in the hull (to reduce its silhouette) was hampered maneuvering in narrow passages and limited mobility over undulating ground (the muzzle being driven into the ground) and wooded country. Furthermore, the center of gravity in such SAU was displaced forward, leading to an overloading of the forward road wheels, often leading to a breakdown of the chassis. In transit, it was also found to be impossible to satisfactory fasten the gun out of battery for travel. At the same time, further increases in the armor protection of German tanks and assault guns required an adequate increase in the combat capabilities of Soviet tanks and SPGs, which entailed the adoption of ever longer barreled guns of greater power. To design such a tank destroyer, based on the chassis of the T-34 tank became practically impossible. A new chassis with a more rational arrangement of major units and subassemblies was necessary.
UZTM's solution of this problem began in the summer of 1944, done in parallel with the creation of the Su-100. Before the end of the year designer N.V.Kurin had developed a number of preliminary designs of new SPG using the chassis of all Soviet tanks existing at that time, both with a change in layout and without. In October 1944 plant presented to the technical review board of the NKTP (Commissariat of Heavy Industry) for examination five projects:
- SU-122P: armed with the 122 mm D-25S gun, at that time with a prototype prepared and having successfully passed manufacturing tests.
- ESU-100, armed with the 100 mm D-10S gun, with a rear fighting compartment and electro-transmission.
- SU-M, armed with the 100 mm D-10S gun, based on the chassis of the T-34 tank, with a rear fighting compartment and with the engine moved to the front.
- SU-M, armed with the 100 mm D-10S gun, on the chassis of the T-44 tank, with a rear fighting compartment.
- SU-44, armed with the 122 mm D-25-44S gun, with the use of subassemblies and chassis of the T-44 tank, and a forward fighting compartment.
The technical review board recognized the Su-m and Su-44 as the best of the projects; and by order of directiveNo.625 to the tank industry, dated October 26, 1944 to the plant of UZTM, it was proposed to finalize the design, to distribute drawings and prepare prototypes of the SU-M and SU-44.
In December 1944, during the course of further development work on the Su-44 it was found that the weight and overall size of the machine was too great, basically because of the five-meter barrel of the D-25S gun. At the same time the SU-M with the rear fighting compartment was found to be compact, its length shortened and its weight consistent with the chassis of tanks in the medium class, while armor was considerably strengthened. Based on these results, the solution accepted was to continue work only on the SU-M, and all work on the Su-44 was terminated by NKTP order No.107, dated March 7, 1945. By the same order the design obtained the designation “Uralmash-1” (Ural Heavy Machinery Plant im. Sergo Ordzhonikidze) and was assigned a date for the production of the first prototype, May 1 1945.
It is here interesting to note that the project of SAU “Uralmash-1” (Ural Heavy Machinery Plant im. Sergo Ordzhonikidze) was developed by the design bureau of the plant of UZTM (Ural Heavy Machinery Plant) under the management Of l.Gorlitskogo still in August 1943, but it was not approved BY NKTP and was “frozen”. In the development of design documentation, the following designers were enlisted: .M.Lekhttsind, I.I.Emmanuilov, A.G.Gayvoro nskiy, G.F.Ksyunin, I.F.Vakhrushev, L.A.Pinus, E.A.Karlinskiy, E.I.Linkova, D.A.Geriev, V.L.Likhomanov, N.N.Efimov, A.D.Nekhlyudov and others. The general leadership was given to the chief designer L.I.Gorlitskiy. The production of two prototypes was conducted during March-April. The first being marked as Su-101, armed with 100 mm D10s gun, and the second, marked as Su-102 with a 122-mm gun D -25s gun.
Design features
The housing SAU was welded from the rolled armor sheets, by which were given the rational slope angles. The thickness of the frontal sheet of housing was equal to 90 mm with the angle of the slope of 27 degrees, the thickness of the frontal sheet of felling - 122 mm with the angle of the slope of 35 degrees. Onboard sheets had a thickness of 75 mm, stern sheet - 40 mm. In this case the stern sheet of housing and felling was carried out by general. Rectangular entrance port, which was being shut by armor doors, was placed on the right side. Round hatchway with the revolver housing mounted the panoramic viewfinder for the commander. Gun D -10s was established in the frontal sheet of housing in the cast armor mask. Its stem spoke in favor of the overall sizes of the housing only on 630 mm. Angle of elevation was 18 degrees, depression was – 2 degrees, and the angle of horizontal guidance was set at 22,5 degrees. The height to bore of gun - is 1760 mm. Ammo rack had a total of 35 rounds. Sighting telescope TSH-19 was installed in addition to one separate panoramic periscope. For anti-infantry and anti-aircraft protection, a standard 12,7 DSHK machinegun with a total of 450 round was installed.
Engine V-2-44 was located along the axis of machine in the forward section of the housing to the right. Driver was placed on the left side of the engine. The aggregates of power transfer were borrowed from the tank T -34 with some modifications to handle the new chassis. The suspension was completely borrowed from the T-44. With the overall mass of only 34,1 tons the vehicle was able to reach the maximum speed of impressive 54 km/h. Crew consisted of four. For the external communication Su-101 used standard 9- RS radio device, while internal comm. Was handled by TPU-3bisF device, by light signaling and tankofonom for the two-way communication of commander with the driver.
Su-102
Su-102 from Su-101 differed only by it only by its main gun, 122-mm gun D -25s. Angle of elevation was equal - 18,5 degrees, depression was at less than half degrees virtually non existing (0 degrees and 24 minutes to be precise), the horizontal traverse was 19 degrees. It is remarkable, that with the apparent small dimensions of the fighting compartment ammo rack composed of 28 shots. Very impressive number considering that 122 mm ammo was in two pieces, propellant separated from the round itself. Total weight of the vehicle grew insignificantly to 34,8 tons.
First trials
During the autumn of 1945 several issues were noticed, and needed to be fixed prior to finalizing the construction. It was necessary to modify a number of mechanisms and devices, in particular the aggregates of ventilation and engine cooling and the internal crew fighting positions. As a result the intensive work of designers and techinicians was implemented to fix the problems prior to the the start of the field tests.
Self-propelled units “Uralmash (Ural Heavy Machinery Plant im. Sergo Ordzhonikidze) -1” had a number of advantages in comparison with previously created domestic SAU. New layout made it possible to make a machine of of more compact, increased the possibility of maneuver in the limited passages and in the broken ground. Crew now could if necessary leave the machine through the stern hatchway under the cover of housing. Powerful armoring also became the result of denser layout. The general estimation of the construction of housing after the range tests by firing was very high: the housing of SAU “Uralmash (Ural Heavy Machinery Plant im. Sergo Ordzhonikidze) -1” proved to be on a higher level than the housing of all other mass produced tanks and SPGs, including IS -2 and ISU-152. Load distribution was also much better and it noticeably decreased wear of the materials. The arrangement of the fighting compartment on the back left an option of mounting even longer barreled guns in the future.
Cramped crew space and overheating remained an issueNo matter how hard they tried, the engineers could not fix all of the problems. It was impossible to improve crew conditions in the very cramped crew space. Cooling was improved, but still condition for the driver were very harsh, and during hot weather almost unbearable. Also, the roof of the vehicle showed signs of shockwaves from the powerful guns, especially in Su-102 prototype.
Successful trials and cancellation
Both SAU successfully underwent all tests and according to their results they were recommended for the adoption in the Red army. Despite the prospects and high performance for its time, with the end of the war, it was decided to terminate further development. One of the survived prototypes Su-101 is on permanent display in the Moscow Kubinka armor museum.
