Gyurza-M-class gunboat

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, Гюрза, Hiurza, 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.
