Censor.NET reports citing the statement by Ukraine's Navy press office.
"We expect the vessel to stay here until approximately Dec. 2. Ukraine's Navy attaches great importance on the visit of the vessel, considering it to be a sign of continuing support to Ukraine," the statement reads.
The vessel deployed from its homeport in Norfolk, Virginia on May 23 and has been sailing in both the Navys 5th and 6th Fleet areas of operation. According to the 1936 Montreux Convention, the international agreement regulating sea traffic through the Bosporus Strait, James E. Williams can only remain in the Black Sea for a maximum of 21 days. When the ship left Norfolk in May, the crew expected to be home for Christmas, according to news reports.
The last U.S. Navy ship to visit the Black Sea was USS Porter (DDG-78), which departed on September 1 after finishing the Operation Atlantic Resolve exercise in August.
