In the aftermath, the Ukraine Navy relocated its main operational base to its Western Naval Base in Odessa. The current fleet consists of 11, mostly small operational ships, one frigate commissioned in 1993 and four corvettes. Russia also returned a to Ukraine, restoring Ukraine's amphibious assault capabilities. On 8 April 2014, an agreement was reached between Russia and Ukraine to return interned vessels to Ukraine and "for the withdrawal of an undisclosed number of Ukrainian aircraft seized in Crimea". Russian Navy sources had claimed the Ukrainian ships were "not operational because they are old, obsolete, and in poor condition". 35 ships were returned before Russia unilaterally suspended the return of the remainder, alleging that Ukraine had failed to renew its unilaterally declared ceasefire on 1 July 2014 in the War in Donbass. 16 minor auxiliary ships are hence yet to return to Ukraine proper.
