They were only superficially similar to the T-90As Rossiyskaya Gazeta said, in the 90s, Ukrainian tank repair plants began to offer foreign countries their own options for upgrading the T-72. However, they were not successful. Discuss
Ukrainians have developed many unusual versions of the tank. For example, the T-72-120, on which they wanted to install a 1200-horsepower two-stroke diesel engine 6TD-2 and a 120-mm “NATO” gun with an automatic loader located in the turret compartment. In addition, the designers, at the request of the customer, could leave the 125-mm 2A46M and mount the 140-mm 55L Bagheera.
However, no one was willing to buy tanks. The military of the vast majority of countries were more interested in used T-55s and T-72AVs. The fact is that Ukraine offered combat vehicles that were not even really tested.
It is also noted that the Ukrainians compared their upgrades with the T-90S, but they were only similar in appearance.
