@mysteryman,
I bef your pardon! Germany withdrew it's forces from NATO comand due to .... we didn't vote in the Security Council with 'yes'.
Those navy ships, however, are still there, only under national command now. (As are quite a few US naval units.)
According to Brigadier Pierre St Amand (NATO) the alliance had so far received offers of 16 ships from a number of countries to implement the mission.
He said the ships included: a command-and-control ship from Italy; 10 frigates, including four from Turkey and one each from Britain, Spain, Greece, Italy, Canada and the US; submarines from Spain, Italy and Turkey; and auxiliary ships from Italy and Turkey.
