The G-5 Motor Torpedo Boat represented a significant evolution from the Sh-4 MTB both before and during WW2. It underwent numerous variations and modifications, with approximately 300 units produced during the war. Initially armed with a single 7.62 mm machine gun and two torpedoes, it was later upgraded to incorporate a 12.7 mm DShK machine gun in subsequent modifications. Throughout the war, the G-5 underwent extensive alterations. Some of these included configurations with dual 12.7 mm DShK machine guns, a single 20 mm ShVAK autocannon (G-5 (ShVAK)), or, in certain variations, an 82 mm M-8 Rocket Launcher, often at the expense of the torpedo launcher (TKA-106).

The boat was introduced during Update 1.79 "Project X" when the Soviet fleet was implemented into the game. Its armament consists of a single 12.7 mm DShK machine gun and two 533 mm 53-38 torpedoes. Like many other reserve MTBs, engagements primarily rely on the gun armament, occasionally utilizing torpedoes for slower, heavier vessels. Being the fastest MTB at its BR, it excels in swiftly capturing strategic points and mounting surprise attacks on the enemy.
