The G-5 (ShVAK) was a further attempt to modify the G-5 Motor Torpedo Boat, aiming to enhance its firepower in service with the Soviet Navy in 1940. The Soviet Navy replaced the traditional 12.7 mm DShK heavy machine gun with the 20 mm ShVAK autocannon, significantly improving its firepower.

This boat was introduced in Update 1.83 "Masters of the Sea" as part of the fleet release into open beta testing. Its 20 mm autocannon serves as a valuable asset on the boat, capable of shredding any lightly armoured boat with short bursts and even posing a threat to some heavily armoured vessels due to its AP belts. Additionally, its torpedoes can effectively target slower-moving vessels.
