The T-126 experimental light tank was built in the summer of 1940 at Leningrad Experimental Automobile Factory #185. The project was developed on the basis of combat experience in Spain with the goal of creating a tank suitable for the conditions of future wars. Only one model of the tank was ever built, and it was never used in combat. The T-126 featured sloping armour, torsion bar suspension, diesel engine, three-man turret, and a commander's cupola, all of which were advanced features at the time. The tank is equipped with a 45 mm 20-K cannon and a 7.62 mm DT machine gun. It is a premium version of the T-50, being its prototype design, it shares it similarities, but actually is better due to much thicker armour all around.

Zhukovsky's Chaika is a distinctive vehicle in mainly appearance. It performs very well and can take bombs and rockets into battle. With a forward armament of 4 x 7.62 mm ShKAS machine guns, it can quite quickly ruin enemy planes, and its payload options allow it to deal with a couple lightly armoured vehicles while it's over the battlefield. Besides that, Chaika can be equipped with rockets and bombs. It is best used as an air superiority aircraft. Due to its fast climb rate, tight turning radius, and speed, it outperforms many of its contemporaries. The plane is painted after the camouflage scheme of Soviet pilot Sergey Y. Zhukovsky in the 127th Fighter Aviation Regiment of the Soviet Air Forces.
