The navy was highly affected after Crimea was seized by Russia as the majority of Ukraine's ships were stationed in Crimea. Ukraine developed plans to rebuild their naval capability even before 2014 by planning to build 4–10 new corvettes at the Mykolaiv Shipyard. This was one of the Soviet Union's largest shipyards and it built Russia and China's only operational aircraft carriers. After the 2014 Crimean status referendum, Ukraine refused to import arms from Russia for its newly-constructed ships, thus it is unclear whether weapons for project 58250 as Ukraine dubbed it, will be built internally in Ukraine or imported from another country.
