The Project 58181 Centaur (Kentavr)/Project 58503 Centaur-LK class is a series of small armored assault craft being built for the Ukrainian Navy. The first two vessels were laid down at the Kuznya na Rybalskomu in December 2016. The 58181 project was developed by State Research and Design Shipbuilding Center on the basis of the Gyurza-M-class gunboats, and the 58503 project number was assigned to the altered design used after construction of the first eight units began (by the contractor that oversaw their construction, PJSC ZLK. Designed for carrying patrol service on rivers and coastal maritime areas, delivery and landing of marines.
The Raptor-class patrol boat, formally identified as Project 03160, is a series of Russian high-speed coastal patrol boats. Boats of the class belong to the 4th rank ships in the Russian Navy. This project was developed by the design bureau of JSC Leningrad Shipyard Pella on the instructions of the Russian Navy. The boats are built at the Pella shipyard in the town of Otradnoye, Leningrad Region. Due to the great similarity in appearance, the boats of the project can be confused with the Swedish CB90-class fast assault craft and other transport and landing boats of the 02510 BK-16 project, developed by the Kalashnikov concern and manufactured at Rybinsk shipyard.
The Snake Island campaign was a period of Russian occupation and military conflict for Snake Island, a small, strategically located Ukrainian island in the Black Sea. On 24 February 2022, the first day of the Russian invasion of Ukraine, the Russian Navy attacked Snake Island and captured it along with its entire garrison, beginning a military occupation of the island. The attack was widely publicized when an audio clip of the Russian cruiser Moskva hailing the island's garrison over the radio demanding their surrender and being told "Russian warship, go fuck yourself" in response went viral, along with initial inaccurate reports of the garrison's deaths. Later on, it emerged that a civilian search and rescue ship trying to evacuate the soldiers was also captured along with the garrison. The ship, its crew, and at least one soldier were subsequently freed in prisoner exchanges.
