The Gyurza-M class / Project 58155 is a Ukrainian small armored gunboat series built by Kuznia na Rybalskomu for river, harbor, lake, and littoral patrol. The class combines a five-person crew with two remotely controlled KAU-30M modules carrying 30 mm guns, grenade launchers, machine guns, and Barrier anti-tank missiles.
Ukrainian Gyurza-M gunboats Berdyansk and Nikopol were directly involved in and captured during the 2018 Kerch Strait incident. During the 2022 full-scale invasion, multiple Gyurza-M boats were captured, one was sunk and later raised by Russia, and at least one Ukrainian Gyurza-M was damaged by a Russian Lancet drone near Ochakiv; a new Gyurza-M, Bucha, was commissioned in 2023 for riverine and coastal defense.
