The 1936
Montreux Convention imposed severe restrictions on the ability of non-Black Sea countries to send naval forces into the
Black Sea. No more than nine non-Black Sea naval vessels can pass into the Black Sea, with the tonnage of ships one non-Black Sea nation can send being restricted to 30,000. The non-Black Sea naval vessels can remain in Black Sea only for three weeks. The Convention also explicitly forbids the passage of
aircraft carriers. On 15 August 2008,
James Cartwright, the vice chairman of the US Joint Chiefs of Staff, said that the United States intended to send two U.S. Navy hospital ships to Georgia. Steven Romano,
European Command director of logistics, said that the US intended to provide supplies to Georgia and added that the US Mediterranean assets might be used for the operation. However, on 18 August, Kathryn Schalow, U.S. Embassy press attache in
Ankara, while noting that a lot of actions for the purpose of humanitarian assistance had been already taking place, demurred answering whether the US asked for permission to allow the
USNS Comfort and the
USNS Mercy into Black Sea, with each displacing 69,360 tons.
Turkey historically was "less than accommodating to the Pentagon's request for
Turkish straits passage" and objected to the US hospital ships entering the Black Sea. However, On August 21, US State Department spokesman
Robert A. Wood said that "Turkey has approved three ships for transit into the Black Sea to transport humanitarian relief supplies to Georgia - that will consist of two
United States Navy ships and a
United States Coast Guard Cutter". ==Deployment of U.S. Forces==
