Carrier Strike Group
A naval formation centered on an aircraft carrier, typically including guided-missile cruisers, destroyers, a submarine, and a supply ship, capable of projecting power anywhere on the globe.
A Carrier Strike Group (CSG) is the primary power projection tool of the U.S. Navy and the most potent conventional military formation afloat. Built around a Nimitz-class or Ford-class nuclear-powered aircraft carrier embarking approximately 75 aircraft, the CSG typically includes one or two guided-missile cruisers, two or three guided-missile destroyers, an attack submarine, and a fast combat support ship.
The carrier's air wing provides offensive strike, air superiority, electronic warfare, airborne early warning, and anti-submarine warfare capabilities. The escorting surface combatants contribute additional air defense through the Aegis combat system, anti-submarine warfare through towed arrays and helicopters, and cruise missile strike via their vertical launch systems. The attack submarine provides an unseen defensive screen and can strike land targets with Tomahawk missiles.
The United States operates 11 carrier strike groups, more than the rest of the world combined. Each CSG can respond to a crisis within days, establishing a sovereign airfield in international waters that requires no basing rights from foreign nations. This unique combination of mobility, firepower, and sustainability makes the carrier strike group the foundation of American global military presence.
