Maybe through the Kerch straight?I was reading the other day Russia has managed to get more missile cruisers and submarines into the Black Sea. Where are they coming from the naval base in Crimea or are they getting access from the Med via Turkey?
Has a clearance of 35m,so would depend of size of ship,and water depth....I'm guessing though.
Think they have a naval base at Tuapse.
