This flexible, heavy strike group can operate in any threat environment. Capabilities support initial crisis response missions and may be undertaken in nonpermissive environments where multiple threats exist, including anti-ship missiles, ballistic missiles, mines and terrorist threats.
This is the routine rotational amphibious force package employed by the Navy-Marine Corps team, providing operational freedom and expanded warfare capabilities at sea and by land with embarked Marines. The ARG/MEU consists of a baseline of three amphibious ships with naval support elements and an embarked MEU. Depending on the requirements, it may deploy with surface combatants and a submarine. When the ARG/MEU is led by a flag or general officer, it is referred to as an expeditionary strike group.
This group can operate independently or in conjunction with other maritime forces to support crisis response or sustained missions. The group may be employed in a limited, nonpermissive multiple-threat environment. Missile-equipped SSGs provide deterrence and immediate contingency response, conduct maritime security operations and are primarily independent, sea-based, mobile groups that will provide sea control and strike power to support joint and allied forces afloat and ashore.
The Military Sealift Command's Naval Fleet Auxiliary Force provides all of the Navy's combat logistics services to the fleet, including fuel, food, ordnance and nearly everything that Navy ships need for extended periods of time. The force also conducts towing, rescue and salvage operations, as well as manages floating medical facilities. These ships are operated by civilian mariners.
