The Project 58155 Gyurza-M class is a series of small armored gunboats in service with the Ukrainian Navy. The first two vessels were laid down at the Kuznia na Rybalskomu (previously Leninska Kuznia) shipbuilding plant in October 2012. Originally it was planned to build nine such vessels by 2017. In December 2013 the Ministry of Defence withdrew its contract. The class is named after the Levant viper, , in Ukrainian.
In mid-2014 construction of the Gyurza-M class was revived and the first two vessels were launched in late 2015. In December 2016 they officially joined the Ukrainian Navy. The new military contract for twenty vessels was to have been completed by 2020.
With the Russian invasion of Ukraine in 2022 a number Gyurza-class boats were captured by Russia, with some being incorporated into the Russian Navy.
On 25 November 2018, two Ukrainian Gyurza-M-class boats, Berdyansk and Nikopol were seized by the Russian Navy. They were captured while they tried to cross the Kerch Strait en route to Ukrainian port city of Mariupol in the Sea of Azov. During the incident, three Ukrainian crew members were injured. The ships were returned on 18 November 2019, but Ukraine accused Russia of returning them in sub-par condition.
Following the capture of Berdiansk by Russian forces, P 179-Vyshhorod and P 174-Akkerman were captured by Russian forces. Russian forces captured another two craft, P-177 Kremenchuk and P-178 Lubny, during the Siege of Mariupol.
On 4 November 2022, a Gyurza-M-class gunboat of the Ukrainian Navy was damaged by a ZALA Lancet drone, the first time a Lancet attacked a naval target during the war.
On 28 December 2023, P-181 Bucha is reported to be part of Kyiv air defences.
