Black Eagle (Not T-80UM2!)
"This new tank was shown for the first time at the second VTTV-Omsk-97 International Exhibition of Armaments, Military Equipment and Conversion Products held in September '97 in Omsk, Siberia region, Russia.
The tank is supposedly not to be fielded with the Russian Army and seems to be entirely on the initiative of Omsk plant (Russian manufacturer of the T-80 series).
It was thought to be based on the T-80U chassis, borrowing most components from the T-80U. Its most obvious external distinguishing feature is the completely new turret (a mockup was presented at Omsk 97) and a lengthened hull with 7 road wheels per side.
The new turret has a larger degree of protection than that of current Russian MBTs, the forward armor is placed at an extremely steep slope, the ballistic shape maximizing protection against APFSDS rounds.
Another innovation is the new automated ammo storage/loader, located in a turret bustle. It is separated from the crew compartment by an armored bulkhead. This design has several advantages. First, the Chechen war has shown that the carousel used in the T-72/T-80/T-90 is too prone to ammo detonation when penetrated, invariably killing the crew. Second, the adopted configuration also reduces Black Eagle's height. Finally, the horizontal ammunition arrangement in the turret bustle permits using longer (and therefore, more powerful) APFSDS rounds, unitary ammunition (rather than separate loading), simplified automatic loading process and an increased rate of fire (expected to reach 10-12 rds/min).
The Black Eagle will have an onboard information system that monitors all essential systems and permits automated data exchange between other tanks and head quarters.
It will be powered by a 1,200hp 16-cylinder turbo-diesel engine, and will weigh around 50 tons.
The complete vehicle, with an actual turret (not a mockup covered by camo netting as in 1997) was revealed at Omsk 99, and was referred to as Object 640. It was apparent that the hull had not been taken directly from the T-80U as originally believed, but was significantly redesigned, the most obvious change being the seventh road wheel.
It seems that most of the additional length has gone into the raised front hull protection and greater glacis obliquity. It also raises doubts if the tank indeed stays in the 50 ton class. The active protection system appears to be a Drozd (probably Drozd 2), not Arena, derivative.
The tank was armed with the longer caliber, improved 2A46M4 main gun, but it was stated that provision had been made for the installation of a new 152mm main gun, indicating that Omsk plant still hopes to win over the Russian Army with this new tank.
The more conventional design over the aforementioned ‘T-95’ design means less technical risk, while incorporating some of the features of Western tanks (primarily ammunition storage), improves export prospects."
T-95/ Nizhniy Tagil Next-Generation MBT
"Only vague details are known about the ‘T-95’, the replacement of all main battle tanks in the Russian Army. The very term T-95 is probably erroneous, and was used by the Russian Defense Minister when he was questioned by the press during a visit to Nizhniy Tagil, where he was shown a prototype of the tank. Possibly he deigned to use a term well-known in the West to avoid getting into detail. However, only in-service tanks are entitled to a ‘T’ designator, and the tank probably remains hidden behind an ‘Object’ designation.
The main gun will be a 152mm smoothbore (incorrect reports have stated 135mm). Such a large diameter will mean extremely powerful, long-range APFSDS, HEAT and HEF ammunition fired at extremely high velocities. Whether it will be able to fire an ATGM like the 125mm guns is unknown. It is not known how this large caliber increase will affect ammunition load and rate of fire. This gun shall be located in an unmanned pod on top of the hull with no crew access to it, and will be fed by an autoloader mounted beneath the turret. This will lower the silhouette/ profile of the tank considerably. The fire control system will be multi-channel; consisting of optical, thermal, and possibly a radar.
Crew protection on the tank will be emphasized to a far greater degree than ever before in any tank design. The level of crew protection should ensure their survival when any anti-tank munitions penetrate the tank from any aspect or angle, thanks to the crew (3 men) placement in a unitary armored pod inside the hull; separated from the main gun and ammunition by an armored bulkhead. A unique drive train suspension system is being tested on this tank that to a certain extent extinguishes hull vibrations and stabilizes its position. The tank will remain in the 50-ton class. The turret and gun placement means that the carousel autoloader that has always meant poor survivability for the crews of Russian tanks is eliminated. The T-95 will almost certainly be able to mount heavy ERA, either existing Kontakts-5 ERA or a new design, along with composite armor.
Fitting of the Shotra-1 OCMS and/or the Arena APS or Drozd-2 APS will also probably be possible.
It will most likely be equipped with a diesel engine, considering the Russian Army’s preference for diesels over gas turbines. Some sources put the T-95 as having cleared the testing stage in 1999, but it has not reached the Army because there is insufficient funding to fund production."
