Gyurza-M-class artillery boat

The Project 58155 Gyurza-M class is a series of small armored artillery boats in service with the Ukrainian Navy. The first two vessels were laid down at the Kuznya na Rybalskomu (previously Leninska Kuznya) 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.

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 is to be completed by 2020.

Operators
The Ukrainian Navy operates six vessels as of October 2018 but lost two of them in November 2018.

Incidents
On 25 November 2018, two Ukrainian Gyurza-M-class artillery 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.
