A new Russian MBT named Chiorny Oriol (Black Eagle) 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.
Until recently, there were hardly any details about the tank except for a couple of words and a poster on the Defendory 1998 held in Greece.
According to the information I have, this tank is being developed in cooperation with and for export to S.Korea and may even feature Korean thermal imagers. It will not be fielded with the Russian Army and seems to be entirely an initiative of Omsk Plant. It originates from the now-closed Nikolai Popov's design bureau at Leningrad Kirov Plant (LKZ) and is now developed by Alexander Morozov.
The tank is built on a T-80U chassis and will borrow most of its components including FCS from T-80U.
The most significant difference between the new tank and T-80 is the completely redesigned turret (at Omsk'97 a full-sized mock-up was presented) and the lengthened hull with 7 roadwheels per side.
The new turret will have a larger degree of protection than the current Russian MBTs. The steep slope of forward armor plates on the turret reflects designers' desire to maximize protection from APFSDS rounds in a duel situation, when tanks fight "face to face".
For additional protection, the tank is fitted with Kaktus ERA and the new Drozd-2 APS.
It was originally planned to install a 152 mm gun that is being developed for a future Russian MBT. However, since this tank is not going to be fielded with the Russian Army, it carries a 125 mm 2A46M-series gun.
Another innovation is a new automated ammo storage/loader, located in a turret bustle. It is separated from crew compartment by an armored bulkhead which greatly increases crew survivability. This design has several reasons. First, the Chechen war has shown that the carousel used in T-72/T-80/T-90 is too prone to ammo detonation when penetrated, invariably killing the crew. Second, adopted configuration also reduces Black Eagle's height by 400 mm by comparison with the T-80 (Perhaps a typo here, since this means that the tank is a mere 1.8 meters in height). Finally, horizontal ammunition arrangement in the turret bustle permits using longer (and therefore, more powerful) APFSDS rounds, unitary ammunition, simplified automatic loading process and increased rate of fire (expected to reach 10-12 rds/min).
Black Eagle's on-board information system monitors all essential systems of the vehicle, and permits automated data exchange with other tanks and headquarters.
The tank shall have a new 1200 hp 16-cyl. turbo-diesel engine and shall weigh around 50 tons.
VTTV-Omsk-99 exhibition have finally revealed the complete vehicle (referred by KBMZ as Item 640) without any netting. Several features became immediately apparent. It was apparent for the first time that the vehicle's hull is not taken directly from T-80U as was originally believed, but was significantly redesigned, the obvious change being the 7th roadwheel. 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 Class 50. The active protection system appears to be Drozd, not Arena, derivative. Although the tank indeed carries the 2A46M maingun, it was stated that provision is made for installation of a new 152mm maingun. This implies that Omsk still hopes to win the hearts of the Russian military with this new tank.
