The Object 279 early is a Soviet tier 10 premium heavy tank.
An early variant of a blueprint project for a high crossing capacity heavy tank with a new configuration scheme. Developed in 1947–1948 by L. S. Troyanov. This vehicle was to feature a low four-track engine, mounted on longitudinal beams that also served as fuel tanks, considerably reducing the chance of fire. These solutions provided high crossing capacity and survivability: the tank could continue moving even with damaged tracks. The placement of the hull above the suspension allowed for a large fighting compartment, and as a result, increased ammunition and an improved autoloader mechanism for a high rate of fire. A functional prototype was manufactured in 1948.

Performance
Being one of the most futuristic appearing tanks featured in game, the Object 279e brings the breakthrough tank concept to a whole new level.
It's parameters, on the first glance, appears to be something in between the IS-7 and the IS-4, with a mid-large calibre gun, thick armor concentrated on the frontal arc and above average mobility & agility. This can actually be much misleading, for that it has one distinguishing benefit off the paper: the chassis design. Object 279e's boat-shaped hull completely remains above its 4 wide tracks. This odd design eliminated the LFP weakspot common on most ordinary tanks, leaving only the turret cupolas somewhat viable target. The suspension elements supporting the hull are also considered spaced armor as the tracks are, shooting through which causes no damage. As such, instead of side-scrape technique one can "head-scrape" in the 279e: Poke the angled glacis and conceal the weaker inner side behind cover. In this way, opponents who have either too low penetration to pen the glacis (which equal most vehicles ingame, and still many even with premium rounds) or too bad gun handling to target the cupolas will eventually perish beneath the M-62T2A gun, with the 279e barely scratched from the effort. The thick protruding edge of the glacis can also be used as a ramming bar to some extent; just be aware that one shall keep its weight in mind. That being said, it's still way far from invulnerability: to keep its weight in reasonable range, its sides and rear plates are far less sturdy than the IS tanks, and has no spaced armor strips to absorb poorly aim shots. Also most likely as a compromise to its unique layout, its hull bottom plate is only 20mm thick! This can be the Achilles heel against more seasoned opponents: exposing it by moving around inclination will directly negate the benefit of not having a LFP; while this pitiful thickness also takes heavy impact from HE shells landing on one's tracks. Getting pinned to death by high RoF guns spamming HE or simply arty bombardment is highly probable. TL;DR -- the armor on frontal arc is more than tough, just take caution abusing that.
Other than the outstanding survivability, its firepower is nothing to be looked down upon. The M-62T2 may not have been new around with its just acceptable penetration and accuracy, but this one boasts improved reload rate, making its DPM comparable to those of the more nimble Chinese HTs. The only issue is the vertical clearance: 5 degrees of depression might not be very handy in facehugs or rough terrain.
Despite inheriting the awful ground resistance of previous Soviet HTs, its comparatively powerful 850hp diesel engine ensured superior mobility to the cumbersome IS-4, and is roughly on par with the Super Conqueror. One won't arrive anywhere in a blink, but it usually will do.
Overall, the Obj. 279e is a brilliant brawler, be it bullying meds or tricking other heavies. It's definitely worth going through the long mission chain.

Suggested Equipment
Documented Tank and Crew Builds
Equipment Setup:
Gun Rammer is mandatory. VStab preferrable to enhance gun handling, yet aim time isn't that long to benefit greatly from a GLD; for the 3rd slot, GLD for handling, Vents for overall performance, Optics to gain more assists or Toolbox to keep the tracks going, at one's own leisure.
Crew Skills
One should already have no less than 1 set of highly trained Soviet HT crew member upon obtaining the Obj. 279e, and this vehicle doesn't require other specific skills than those one would train on techtree peers, whether the IS line or the KV line. However, note that its crew setup doesn't fit that of the IS-7's, with no 2nd loader slot (who doubles as radioman); other 3 top tier Soviet heavies all have identical crew setup.

Historical Info
Predecesor: Object 726
The Object 726 was supposed to expand the joint work of OKBT LKZ and VNII-100 institutes on the project of a new experimental heavy tank proposed by L.S. Troyanov. Conducting full-scale studies on this tank made it possible to make a decision on a new chassis in future tank building, as well as the practicality of such combat vehicles for special operations in some specific areas of the country (the Far North, deserts, etc.).
Design
The general idea of the new layout scheme of a heavy cross-country tank was presented by L.S. Troyanov back in 1947-1948 in a preliminary design entitled 'Object 726'. Due to the width imposed by railway transportation limits, the optimal idea found was to use the entire width to accommodate a four-track running gear. The project noted:
“Using the entire width of the hull to transfer load to the ground through the presence of four identical powered tracks allowed to place the required number of track rollers (with a small load on the roller) and reduce not only a purely normative indicator, average specific ground pressure, but also the actual specific pressure, which deforms the track and determines the degree of submersion. Almost the entire underside is isolated from the ground by the tracks.
Increasing throughput as such, and reducing the resistive forces on soft terrain, at the same time contributes to an increase in ride smoothness when driving at high speeds. The presence of four tracks increases the survivability of the tank. In case of incapacitation of one of the independent tracks, two middle or middle and extreme sides, the machine can continue to move and maintain controllability. Longitudinal beams, passing along the symmetry axes of the right and left pairs of tracks, make it possible to mount a low chassis on them, which is not achieved with a common suspension on the body. The beams also serve as a tank to accommodate the entire fuel supply, which has been completely removed from the hull to eliminate fires.
The hull is placed on top, above the low chassis, occupying again the entire permissible width specified, due to which it is possible to develop a wide fighting compartment over its entire surface area, located between the tracks in existing heavy tanks and usually not exceeding half the total width. There is the possibility of placing an increased stock of ammunition in places accessible for the loader and the implementation of automation of the loading process to increase the rate of fire. With a large body width, the required volume is obtained at a significantly lower height, which gives both a transportation and a concealment advantage.
Construction of the turret is also improved, since the tower can be made without a tail compartment that was usually used to place ammunition, due to a commonplace small capacity of hulls. The presence of a tail compartment significantly increases the silhouette of the most striking upper part of the machine. The capacity of the wide hull allows storage of the entire stock of ammunition in a less vulnerable and more protected place, eliminating the tail compartment of the turret.“
Development
It should be noted that as early as 1948, the team completed a working model of the tank with a four-track running gear at a scale of 1:10, controlled by wire. In addition to turns and overcoming a number of obstacles (ditches, grooves, rises, etc.), the model proved the possibility of self-unditching on soft terrain by driving power to the middle tracks in the direction of movement opposite to the movement of the extremity tracks.
To check the cross-country ability and agility by the end of 1952, as a result of the joint work of VNII-100 and OKBT LKZ, an experimental four-track machine equipped with the necessary measuring instruments was made. At the same time, it was planned to draw up blueprints for creating other special tracked vehicles based on the tank (artillery tractors, self-propelled artillery guns, heavy-duty transporters, engineering vehicles), intended for use in difficult terrain conditions (for example, in swamps or snow).
In 1953, comparative tests of the experimental four-tracked vehicle and series-produced tanks (T-54 and T-10) were held, which showed Object 726's clear advantage in mobility. Draft studies of the machine, carried out in accordance with the project for a promising heavy tank as well as the mock-ups of its various tests, were presented to the Ministry of Transport and Heavy Engineering in March, June, and November 1953.
In order to ensure reusability of the project in other types of vehicles, on the instructions of Deputy Minister Yu.E. Maksarev, VNII-100 completed projects for a heavy artillery tractor of high cross-country capability and a light amphibious armored personnel carrier with a special four-track chassis. These projects, with all the necessary explanatory materials, were also sent to the Ministry of Transport and Heavy Engineering.
Abandonment of the Project
In early 1954, VNII-100 began to develop a conceptual design of a heavy tank according to a completely new layout using a four-track chassis, which provided significant benefits in cross-country and a significant increase in the size of the fighting compartment. However, due to the lack of approval for the design of such a tank, these works remain largely a mystery. Until the end of 1954, the institute completed only the justification of the parameters laid down in the blueprints of the tank and continued testing the four-track experimental vehicle to study the chassis agility in various conditions. At the same time, the proposed machine weight was brought up to 88 tons.
Object 279 - Made for Nuclear Battlefields
Although the T-10 was the last of the Soviet heavy tank in series production, other heavy tank designs did follow it. Around 1955, a dual programme was begun to examine alternative heavy tanks for the future - Object 277 and Object 279. The main feature shared in common was an advanced version of the 130mm gun developed for the ill-fated IS-7 heavy tank, mated to optical rangefinders for greater long-range accuracy. The new turret included an ammunition assist system for the loader and was fitted with infra-red night fighting equipment as well. Both tanks would share a very similar turret design. However, the hull of both tanks was significantly different. The Object 277 used a modernized hull evolved out of the T-10 chassis, but lengthened with an additional set of road wheels. The team headed by L.S. Troyanov, however, came up with a far more radical approach.
Project and Development
Troyanov's Object 279 was designed to fight on the nuclear battlefield. Beginning in 1953, the Soviet Army had participated in a number of nuclear tests, placing several tank designs in the blast area. In September 1954, a special atomic bomb test was conducted in the Totskoye region with selected army units taking part. It became evident at the tests that tanks near the nuclear blast area were often knocked over by the shock waves that ensued. Although overturned, the tanks were intact and still functional. This led to the requirement for a tank that could survive a nearby explosion of a tactical nuclear weapon. Troyanov's approach to the requirement was to increase the surface area of the track and reduce the center of gravity. In addition, the hull would be aerodynamically shaped to withstand the high-speed wind that accompanied the blast's shock wave as well as to reduce radiation effects to the crew inside. The vehicle was fitted with hydropneumatic suspension so that the entire chassis could be lowered closer to the ground to further resist overturning.
The prototype of the Obiekt 279 was completed in 1957. It had a remarkable appearance. The suspension was modular with four sets of running gear. Each pair of running gear were attached to a central core which also served as the main fuel supply. The hull was oval in shape when viewed from above, with very steeply angled sides. The hull configuration permitted a great deal of dead space that could be used to contain anti-radiation material. It was powered by a 1000 hp, 12 cylinder diesel engine which gave it excellent mobility for a 60-ton tank, and was capable of speeds of up to 35 mph. The turret and armament of the Obiekt 279 were essentially similar to those on the Obiekt 277, with a 130mm gun mounted in a large, conventional 3-man turret, with a coincidence range-finder. The outer panels of the hull were hinged to allow them to swing down and out of the way during rail transport. At the rear of the vehicle were supplementary external fuel tanks.
Fate
The tests on the tank were successful in view of the novelty of the design. But the hull construction made the tank extremely expensive to produce and it was never accepted for service. By the mid-1950s, Nikita Khrushchev had emerged as Stalin's heir. Khrushchev was faced with many of the same problems as Gorbachev in the 1980s, namely a bloated military and a stagnant economy. Major cuts for the armed forces were planned, both in manpower and equipment. The heavy tank, in particular, was viewed by Khrushchev as evidence of the 'old-thinking' and in 1960, he ordered heavy tank production to be terminated. Undoubtedly the strangest Soviet heavy tank, the Obiekt 279 is still preserved at the Kubinka armory museum near Moscow.

Historical Accuracy Errata
The model in-game was known as Object 726 and it had had no direct connection to the actual Object 279, although the design information and testing results from the Object 726 project was used as a basis for the development of the Object 279.
- The actual Object 279 was developed from 1957-59 and one surviving example can still be found at the Kubinka Tank Museum. The Object 279 has a more disk-like hull with 269mm of maximum armor thickness, with effective armor easily surpassing 400mm.
