It’s composed of roughly 7,500 personnel, an aircraft carrier, at least one cruiser, a destroyer squadron of at least two destroyers and/or frigates. A carrier strike group also, on occasion, includes submarines, attached logistics ships and a supply ship. Carrier strike groups comprise a principal element of U.S. power projection over the world’s oceans.
