The Object 263 is a Soviet tier 9 tank destroyer.
The development of a heavy tank destroyer on the basis of the IS-7 heavy tank was started in 1950. Three design projects were developed, one of which resulted in a full-size wooden prototype. However, further development was discontinued due to phasing out mass-production of the IS-7.
The Object 263 was once among the ranks of Tier X Russian Tank Destroyers (before being replaced with Object 268 Version 4 in patch 9.22). Affectionately nicknamed the "The Boot of Stalin", it was well-known for its rapid-firing gun with high DPM, unexpectedly strong frontal armor, and great mobility.
The Object 263 is now a Tier IX vehicle with toned down parameters. It has become a cumbersome "Assault Gun" with poor dispersion, poor DPM, reduced traverse speed, and weaker side armor. It retains its good top speed and excellent frontal armor but this vehicle's glory days are long since gone.
Always avoid getting flanked while playing this vehicle, as your sides and rear won't stand any shots. Sidescraping in this vehicle is not generally recommended due to weakspots and its easy-to-hit ammorack. Facehugging other tanks is highly advised against as your engine deck is a large and very easily hit weakpoint, especially if the other vehicle is tall.
The mobility on the Object 263 is rather flexible, with great acceleration and top speed, allowing it to get into position quickly and support your team where needed. Another defect of this tank is the non-enclosed superstructure, exposing the crew and critical interior components. Direct hits from artillery will devastate you if they hit the open cabin, or leave you quite battered.
The Object 263 leads to the Object 268 Version 4.

Player Opinion
Pros and Cons
Pros:
- Excellent forward/reverse speed and acceleration
- Excellent frontal armor, resilient even against premium rounds
- Excellent at ramming other tanks thanks to its speed, armor and weight
- Great aim time and gun handling for a large caliber TD gun
- Decent concealment for a rather large tank
Cons:
- Inferior alpha damage and penetration compared to Object 704
- Thin side and rear armor with an open cabin, vulnerable to artillery
- Poor gun depression and limited horizontal gun traverse angles
- Poor hull traverse speed, vulnerable to flanking
- Poor dispersion, even at mid range
Performance
Formerly a Tier X tank, the Object 263 was relegated to Tier IX with the introduction of the Object 268 Version 4. As far as high tier tank destroyers go, it is rather unusual in that it has excellent gun handling, a very high speed with good power to weight ratio to boot, and a somewhat underpowered gun with decent yet unspectacular alpha damage and penetration (comparable to the German Jagdtiger and the Chinese WZ-111-1G FT), a fairly limited gun arc with poor gun depression and disappointing dispersion.
That said, the Object 263 performs quite well in the role of an "Assault Gun" - Rather than sit in bushes as an ambusher, it can keep up with medium and heavy tanks thanks to its good speed, and proper positioning makes it a very tough target on the front lines, where its excellent frontal armor and good health pool provide decent survivability.
Unfortunately, everything good about this tank is concentrated on the frontal arc - It has an open cabin (which makes it quite vulnerable to artillery), and its sides / rear are poorly armored and vulnerable to virtually any vehicle this tank can come across. While its upper plate and frontal superstructure are tough, the Object 263 has a weak frontal lower plate like most vehicles.
Overall, the Object 263 rewards well-thought aggression. Over-committing or being flanked is usually a death sentence, so the player will need to mind their positioning and the presence of allied cover at all times. This tank lacks accuracy to hit weakspots effectively and penetration to go through the frontal armor of tougher targets (unless one opts to keep the stock gun and use a lot of premium ammunition), so challenging extremely durable tanks such as the Type 5 Heavy or its own successor the Object 268 Version 4 in frontal engagements is ill-advised.
Against same or lower-tiered tanks however, the Object 263 can be a nightmare to encounter, especially with teammates as backup and/or in a corridor where its flanks are covered.
Early Research
- Research the suspension
- Research the engine
- Research the 130mm S-70A gun
- The R-113 radio carries over from the SU-101 and can be installed immediately
- The 10RT-26 radio can be researched on other tanks such as the Object 416 and T-54 ltwt

Historical Info
At the end of the 1940s in the Soviet Union, Nikolai Fedorovich Shashmurin created the heavy tank IS-7. It had a unprecedented armament and a good armor. But a series of events associated with the emergence of new armor-piercing ammunition and features of the road network in the country, led to the closure of the project. The IS-7 was never put into service thanks to this. At the same time, the IS-7's chassis earned a number of positive reviews, and some representatives of the military control of the country were in no hurry to turn away from it. The 130-mm gun was also a powerful gun for its time.
In this regard, in 1950 the designers of the Leningrad Kirov Plant started work on a self-propelled artillery based off the IS-7 chassis. The project received the designation of "Object 263", and the lead designer of conceptual design was named V.S. Starovoytov. At first three versions were created of the newest self-propelled gun, differing from each other by certain aspects of the design. While working on "Object 263" these choices are "shared" by different aspects of the design and, ultimately, in the program there is only one version, and which was intended for a great future.
Since one of the main requirements for the vehicle was the unification with the IS-7's transmission, its chassis was taken virtually without changes. Motor and transmission group remained the same: 12-cylinder V-type diesel M-50T capacity of 1,050 horsepower and a six-speed gearbox. The same can be said about the suspension, wheels and tracks. With all of this general assembly of the housing has been substantially adjusted. Reinforced cutting self-propelled guns had to be placed in the rear of the chassis because the engine and gearbox have been moved to the front. Fuel tanks, in turn, were placed in the middle of the armored hull. Changing the alignment of the tank associated with the relinking was offset by the increase in thickness of the armor. First, it should be noted forehead "Object 263". In contrast to the forehead of the tank IS-7, He was made not by the "pike nose", and represents a single combination of straight panels. The main plus of the location of armor panels at an angle to each other is to increase the level of protection in relation to "direct". For this reason, the "Object 263" offered to equip the front plate of a width of 300 mm. The sides of the housing in the project were still the smallest thickness of 70 to 90 mm. As for the armored cabin, then she had a formidable defense: the frontal plate of 250 mm and 70 mm on the side. With such armor "Object 263" could withstand fire from all available guns medium tanks and a number of more powerful guns.
The main armament of self-propelled artillery "Object 263" was to be the S-70A cannon. Practically, this was a derivative of the S-70 gun used for the IS-7. This project, Made in the Central Artillery Design Bureau under the V.G. Grabin, returned to the more pre-revolutionary naval gun B-7-caliber of 130 mm. It should be noted that several deep modernization took place and modified the gun, and C-70A had almost nothing in common with the original B-7 except caliber. The S-70A had a decent size, first a barrel length of 57.2 calibers. In addition, the breech and recoil device were larger and more extended. Because of this assembly, the breech of the gun almost reached the back wall. For this reason, a spade was installed in the rear to absorb recoil. It was assumed that before the fight crew will drop this item and are able to work without fear of damage to the tank. In addition, a roomier redesign increased the floor space of the crew compartment, which could significantly facilitate the work of the crew.
The 130-mm gun had a very great impact. Because a slotted muzzle brake system and recoil, a mechanism had to be added, resembling a dozer blade. Existing photo layout "Object 263" shows that in the last bottom position he held up to discover the lowered aft leaf cuttings. Along the sides of the cabin, on the inner side of them were located holders for ammunition. Shots were fixed separately loaded by seven on each side. For convenience, the shells were placed in a holder sleeve — in the other. Loading of the gun was the duty of 2-crew: loader and his assistant.
All in all, the crew SPG "Object 263" was to reach 5 people: the commander, a driver, gunner and two loaders. For direct fire crew had sight of TP-47, and to fire from concealed positions, the TS-46 sight was equipped. The estimated rate of "Object 263" was not great — in a minute the crew could manage to do less than one-half shots. The main premise of this was specific cutting assembly that prevented access those features that were in the JS-7 (about 6 shots). The low rate of fire, according to the views of military and developers should be compensated by the highest firing features a long-barrel gun. So, from a distance of 2000 meters the S-70A with the use of armor-piercing projectile BR-482 was to punch up to 160-170 mm homogeneous armor (at an angle of meetings at 90 °).
First, in 1951 the latest conceptual design of self-propelled gun was ready, and it was presented to the commission of the Ministry of Defence. The military brass acquainted with the works of designers LCZ, then started assembling the full-scale mock SPG. On the model was planned to test some ideas and identify prepyadstviya assembly, ergonomics, etc. Just weeks after the end of the assembly layout "Object 263" order came from Moscow: finish work on the project. Of course, a 130-mm gun was a very good argument on the battlefield. But the calculated mass of the newest self-propelled artillery was at 60 tons. It was 8000 pounds less than that not so long ago closed the project IS-7, but still a lot of practical use in the existing criteria. The design of self-propelled, on a theoretical level, could be eased. But only at the cost of reducing the level of protection that it would be far not the most sensible solution. On the totality of the advantages and shortcomings main armored management made it apparent that in the Russian army, this technique is not necessary. The only built mock "Object 263" was dismantled, while the construction of the SPG "in metal" never happened.
