Ukraine managed to save, relocate 50% of its vessels from Crimea during peninsula's annexation - Minister Poltorak http://www.pravda.com.ua/news/2016/06/28/7113041/

NOTE: the Ukrainian Crimean Admiral who defected to Russia when they invaded Crimea is now the Russian Naval Commander for the Baltic Fleet....now convince me he has not be working for the Russians for years......he was the one who initially gave the command for all Ukrainian naval vessels to remain in Crimea instead of immediately leaving in the first days of the takeover.
