Experimental heavy tank "Object 279"
Corps cast a curved shape with a thin sheet cumulative screens that protected the hull front and sides.
Tower spherical and with thin-sheet screens. The thickness of the frontal armor hull was 269 mm, and the tower - 305 mm.
Armament consisted of a 130-mm gun M-65 and the coaxial 14.5-mm machine gun KPVT. Cannon was supplied with semi-automatic loading mechanism, a mechanized stowage for whizzbang , two-plane stabilizer arms "Thunderstorm", stereoscopic range finder TFD-2S with semi-automatic guidance system. The tank was equipped with a complete set of infrared night vision devices. Ammunition of the gun was 24 whizzbang, machine gun - out of 300 rounds of ammunition.
Powerplant tank:16-cylinder four-stroke diesel H-shaped DG-1000 950 hp at 2500 rpm or 2DG-8M 1000 hp at 2400 rpm. with horizontal cylinders.
Transmission includes a hydro transformer and a three-stage planetary gearbox.
The highlight of the tank was the chassis - four tracks propulsive, placed under the bottom of the case. On each side was a block of two tracked propulsion units, each of which consisted of six twin-not rubberized rollers and three support rollers, rear driving wheel location. Hydro pneumatic suspension.
The crew consisted of four persons, of whom three - commander, gunner and loader - located in the tower. Place the driver was in front of the center, but here there was a hatch to seat in tank.
Area armor - 11.47 m 3
The design of the chassis makes it impossible to tank sat on the bottom on land - this provides high permeability through the deep snow and swampy terrain. However, the chassis was very complex in construction and in operation and made it impossible to reduce the height of the tank.
According to the results of tests of "Object 279", held in 1959, revealed a number of serious shortcomings chassis:losing efficiency when driving on slimy ground, the complexity of repair and maintenance, production of some components and assemblies and change height for tanks. Already at that time it became clear that the "Object 279" was not destined to become a serial tank: he was the most ambitious, highly specialized and expensive of the three experienced heavy tanks and he had to give way to a Object 277 or Object 770 .
