The SB 2M-103U MV-3 is a modified version of the Soviet high-speed front-line bomber, the SB-2 (also known as the ANT-40), which was developed by the Tupolev Design Bureau and is its the most mass-produced aircraft. This version features a new liquid cooling system for the M-103A engines in the form of tunnel radiators that alter the appearance of the engine nacelles and enhance aerodynamic performance. The gunner's turret, which protected the top of the plane, was redesigned and placed in a spherical MV-3 turret. This allowed the gunner to fire in almost any direction in the upper sphere.

The SB 2M-103U MV-3 was introduced to the game prior to the open beta. The aircraft's primary use is bombing. Despite its low rate of climb and poor maneuverability, it is capable of reaching speeds higher than those of pre-war aircraft. It has three ShKAS machine gun turrets that reliably protect the bomber.
