In its invasion and annexation of Crimea, Russia has seized 51 vessels belonging to the Ukrainian navy, according to information compiled by Dmitry Tymchuk, director of the Center of Military and Political Research in Kyiv.
Among the Ukrainian vessels reportedly captured by the Russians are submarine Zaporizhia, management ship Slavutych, landing ship Konstantin Olshansky, landing ship Kirovohrad, minesweeper Chernihiv and minesweeper Cherkasy.
The Cherkasy was the last of the ships to have been overtaken following weeks of threats and ultimatums to surrender. It was finally chased down and overtaken by the Russian navy on March 25 after failing to slip past a blockade of two ships intentionally sunk by the Russians to trap it and other vessels in a narrow gulf, keeping them from escaping into the Black Sea.
As of March 26, just 10 Ukrainian vessels remained in its navy's possession, including frigate Hetman Sahaydachniy, gunboat Skadovsk, intelligence ship Pereyaslav and diving vessel Netishin.
