a U.S. Navy carrier strike group typically includes:
* A supercarrier commanded by an aviation community captain (O-6) who reports directly to the commander of the CSG. The carrier provides a wide range of options to the U.S. government, ranging from simply showing the flag, to attacks on airborne, afloat and ashore targets. Because carriers operate in international waters, their aircraft do not need to secure landing rights on foreign soil. These ships also engage in sustained operations in support of other forces. The carrier is the flagship of the battle group, with the commanding rear admiral on board, making use of the advanced combat direction center and communications suite.
* A carrier air wing (CVW) commanded by an aviation community captain (O-6) (or colonel in the case of a Marine serving as CAG) who reports directly to the commander of the CSG and is known as the "Commander, Air Group" (CAG). The carrier air wing typically has up to nine squadrons commanded by a commander (O-5) (or lieutenant colonel if a Marine squadron). The CAG and CO of the carrier are equal in status under the Commander of the CSG (historically, before 1983, the CAG was a department head under the Captain of the ship, but Secretary of the Navy John Lehman created and instituted the concept of a "Super CAG" with the same seniority as the CO of the carrier).
* A destroyer squadron (DESRON) commanded by a surface community captain (O-6) who reports to the CSG commander and commands the escort ships.
* One to two Aegis guided missile cruisers (CG), of the Ticonderoga classa multi-mission surface combatant, equipped with BGM-109 Tomahawk missiles for long-range strike capability.
* Two to three guided missile destroyers (DDG), of the Arleigh Burke classa multi-mission surface combatant, used primarily for anti-aircraft (AAW) and anti-submarine (ASW) warfare, but it also carries Tomahawk missiles for long-range strike capability.
* Up to two attack submarines, usually of the Los Angeles-class; in a direct support role seeking out and destroying hostile surface ships and submarines. More frequently, however, the submarines will try to maximize their advantages in stealth by operating independently in support of the battle group.
* A combined ammunition, oiler and supply ship (AOE/AOR), usually Supply-class (T-AOE); provides logistic support enabling the Navy's forward presence: on station, ready to respond.[16]
An Expeditionary Strike Group (ESG) also uses the same escort construct, but is centered on 3 Amphibious Ships, LHD or LHA, LSD and LPD and an embarked Marine Expeditionary Unit (MEU).
