Description

The Object 279 is a gift rank VI Soviet heavy tank with a battle rating of 8.7 (AB/RB/SB). It was introduced during Update 1.97 "Viking Fury" as a reward for the "Space Race" event.

The Object 279's unique look comes with its design as being more capable of cross-country travelling in a possible nuclear warfare scenario. This produces its unique hull shape, four-track designs, and a large 130 mm cannon to deal with threats.

Upon release, Object 279 was nicknamed "Moon Rover" by the War Thunder Community.

This tank is the peak of steel armour design, having its armour only consist of homogeneous steel armour. It is also arguably the most well-armoured heavy tank in the game. Getting the exact armour thickness of this tank is quite tricky due to the cast nature of its outer shell. But that won't affect the way one may view its survivability, at the very least the armour thickness of the hull may reach up to 300 mm when faced frontally (excluding the driver's hatch, which is 30 mm flat). The middle of the hull (area below the driver's hatch) is the least angled part of the tank besides the tank's rear, and thus is usually the first spot that is shot at, whereas the sides surrounding this area (left and right parts of the hull when faced front) can reach absurd amounts of thickness, even reaching up to 1000 mm due to extreme angles. However, this will not stop any APFSDS rounds, which are abundant at its BR. Most, if not all tanks at your BR can penetrate you from the front.

The turret is arguably the most armoured part of this tank. Again, getting the exact thickness is difficult but it is guaranteed to be very hard to penetrate, even APFSDS shells will have trouble going through certain spots of this tank. The only prominent weak spot of this turret is the mantlet and machine gun port on the left side of the gun when faced front. Going through the mantlet will more or less only break the gun breech in most cases. One usually shoots the rear side of the turret because that is where the ready rack is located.

It is important to mention the cramped crew spacing. It is like most, if not all, Soviet tank designs where the engineers threw the entire concept of crew comfort out the window. This is important when it comes to the survivability of the crew whenever a shell is able to punch through its stubborn shell. The crew spacing is quite cramped and thus more susceptible to shrapnel damage caused by spalling. On the bright side, most nations have given up on the concept of APHE shell at around this tank's BR so the chances of one-shots are reduced to a degree. Though there are unlucky times when a shell goes through the plate and hit the ready rack behind the gun breech.

Another feature worth mentioning on this vehicle are its self sealing fuel tanks located along the tracks of the tank. To the inexperienced player, these may be an appealing target but that is not recommended unless the intention was to interrupt a repair, most of the time this will only cause a fire and maybe break some tracks (causing a fire is pointless due to the self extinguishing feature). A more recommended target on the side is the bulge made to accommodate the size of the turret (this bulge is also present on the T-62), it is the flattest part of the tank, besides the rear.

All around, this tank is a very hard nut to crack but one should not rely on its armour to stop incoming projectiles. It shares at least some similarities with the T-10M and it has a similar playstyle.

The mobility is good for a vehicle of its size and weight, with a -18 km/h reverse speed, meaning it can actually back out of situations. As a heavy tank, the turning capabilities remain sub-par and the Object 279 loses a lot of speed when turning.

Notes:

  • Projectiles and propellant bags are modeled individually and disappear after having been shot or loaded.
  • Both racks 6 are first stage ammo racks for projectiles and propellant bags. They represent 13 shots and get filled first when loading up the tank.
  • They are also emptied early: the rack depletion order at full capacity is: 6 - 1 - 2 until 5.
  • Simply not firing when the gun is loaded will move ammo from racks 1-5 into racks 6. Firing will interrupt the restocking of the ready racks.

Mount Capacity (Belt) Fire rate Vertical Horizontal

The KPVT is an very effective machine gun, on par with certain autocannons in terms of penetration, and can easily shred lightly armoured vehicles or even the sides of certain MBTs thanks it its 45 mm of penetration. The muzzle velocity of the KPVT is almost the same as the main gun, meaning it can be used as an ranging machine gun.

Usage in battles

The Object 279 is in a position where its main gun can penetrate most things it faces, and the large HE filler guarantees a knock-out. However, the hull is weak, unless you are in a full downtier, it should definitely not be relied on. The turret, on the other hand, is incredibly strong. The Object 279 plays quite well like a tank destroyer, using your 1,000 m/s APHE shell and strong turret armour to quickly peek and take pot-shots at enemy positions. This strategy is effective in uptiers. In a full downtier you can use it like a heavy tank, rushing caps and storming enemy positions, but HEATFS is abundant even at 7.7 and will end you fast.

Pros and cons

Pros:

  • Great 130 mm gun; able to one-shot majority of the enemy tanks
  • Main gun has a two-plane stabilizer
  • Good overall mobility for its weight
  • Access to rangefinder and NVD
  • Coaxial 14.5 mm machine gun is great for dealing with light vehicles and aircraft
  • Fuel tanks are self-sealing and will extinguish by themselves without incurring damage
  • Extremely angled and thick cast armour
  • Quick reloading speed for the size of the gun, first stage ammo consists of a 13 shell auto loader
  • Can survive multiple hits from an ATGM frontally
  • Turret armour is extraordinarily tough, even against APDS rounds
  • Good reverse speed
  • Secondary machine gun can act as a ranging MG
  • Has great armour penetration that rivals early APFSDS rounds and packs an explosive punch

Cons:

  • Inadequate turret traverse speed
  • Inadequate depression angle, a feature shared by all Soviet tanks
  • Vulnerable to high-calibre HE rounds; pylons connecting tank to tracks make for very appealing targets for such shells
  • Most tanks at your BR can penetrate you from the front
  • Very long main gun barrel can be a liability, allowing observant enemies to spot the tank hiding around corners
  • Low muzzle velocity compared to APFSDS and APDS shells commonly found at this BR
  • APFSDS will almost always knock you out because of your ammo rack
  • No laser rangefinder

History

Object 279 in the Kubinka Tank Museum

The Object 279 heavy tank was a combat vehicle intended to break through prepared defenses of the enemy in difficult terrain such as swamps, deep snow and vertical obstacles like boulders, hedgehogs, etc. Such cross-country capability was achieved through four tracks. It was developed between 1954 and 1960 jointly by OKBT LKZ and VNII-100 in Leningrad under the leadership of L. S. Troyanov. The presentation of the prototype for factory tests, as well as the hull and turret for firing tests, was planned for the last quarter of 1957 and the production of two machines by the second quarter of 1958.[1]

By March 1956, the preliminary design was prepared and the technical project by December of the same year, having a 1:1 size wooden mockup by the 30th of December. In the summer of 1957, two sets of hulls and turrets were manufactured, and their armour was tested by shelling at the NIIBT polygon. The technical project was finalized by November-December of 1957, having further increased armour protection. The deadlines for the new experimental vehicles were adjusted due to the large backlog of components needed, ending up in the last quarter of 1959 for the factory tests sample and second quarter of 1960 for the last two samples. The factory prototype passed the factory tests and drove for 502 km (with the engine running for 86 hours). The second prototype was successfully completed but the third prototype did not finish assembly. [1]

At the direction of GBTU alongside the government, the project was terminated in January 1961 with the first and third prototype being sent to the NIIBT landfill, and the second prototype left in storage at VNII-100.[1]
