I was making the point that the writer seems to have finally accepted that carrier based aircraft often support other forces - such as detached ships doing ASW, a force clearing mines, amphibious forces, logistics shipping. This was intended as a general point, but one very relevant within the NATO sphere. The Black Sea is a very unlikely theatre for carrier operations, due to geographical constraints, and the Montreux convention. However, the Black Sea is only part of the Mediterranean region. As you note, there are assets based in Syria to be kept an eye on. We do not know exactly what exercises and operations the CSG21 group will participate in.

'comprised of' is considered acceptable usage by the Oxford English Dictionary, and has been used by writers of note for centuries.
