Navy would be able to deploy almost double the number of independent operational groups, from 19 to 38. The ESG is similar to the ARG except that with the ESG concept, the U.S. Navy introduced a new concept based on the ARG, the naval expeditionary task force or, as it is also known, the expeditionary strike group (ESG). Normally one of the ARGs was in the Mediterranean Sea and Persian Gulf or Indian Ocean area, and the other two were in the western Pacific Ocean. The Navy had two to three ARGs deployed at a given time. The ARG consisted of a group of various ships known as an Amphibious Task Force (ATF) and a Landing Force (LF), which normally consisted of United States Marines and, on occasion, could consist of United States Army troops.Īn ARG is composed of an amphibious assault ship ( LHA/ LHD), a landing platform/dock (LPD), a Landing Ship, Dock (LSD), and a Marine Expeditionary Unit (MEU), which includes a Marine Infantry battalion landing team, AV-8B Harrier II aircraft, CH-53 Sea Stallion, CH-46 Sea Knight, AH-1 Sea Cobra, and UH-1 Huey helicopters. One of these concepts was the amphibious ready group (ARG). The United States Navy has always been involved in developing different military concepts to improve the rapid deployment of naval power and troops from one point to another. An expeditionary strike force (ESF) integrates the CSG and ESG with the sea-basing functions provided by the maritime prepositioning force (future) to provide an even more potent capability. The ESG concept combines the capabilities of surface action groups, submarines, and maritime patrol aircraft with those of amphibious ready groups (ARGs) and Marine expeditionary units (MEUs) ( special operations capable) to provide greater combat capabilities to theater combatant commanders. Navy fields nine expeditionary strike groups and ten carrier strike groups, in addition to surface action groups. The ESG concept was introduced in the early 1990s, based on the Naval Expeditionary Task Force. In contrast to carrier strike groups (CSGs), which emphasize air power and are led by a supercarrier, ESGs are strongly suited for amphibious warfare and are led by an amphibious assault ship (currently of the Wasp or America classes).

In the United States Navy, the expeditionary strike group ( ESG) is a coordinated group of surface ships, aircraft, submarines, and other naval assets. Ships of an Expeditionary Strike Group, circa early 2014
