NATO naval exercise underway in Black Sea

Sea Shield 18, Romania's premier military exercise, is underway in the Black Sea. More than 2,300 troops from Bulgaria, Greece, the United Kingdom, Spain, the United States, Turkey and Ukraine are participating alongside a vast contingent from the Romanian Navy.

Two Romanian frigates, two corvettes, two missile-carrying ships and two sea dredgers are leading the maritime element of the NATO exercise. NATO has been enhancing its presence in the Black Sea since the Ukrainian crisis in 2013.
