Expeditionary Strike Group

The Expeditionary Strike Group, or ESG, is a concept introduced in the U.S. military in the early 1990s, based on the Naval Expeditionary Task Force. The U.S. Navy fields 12 Expeditionary Strike Groups and 11 Carrier Strike Groups, in addition to surface action groups. ESGs allow US naval fleets to provide highly movable and self-sustaining forces for missions in various parts of the globe.

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 Marine Corps and the Navy are conducting a series of experiments to explore the ESG and ESF concepts. As noted, the ESG concept combines the capabilities of surface action groups, submarines, and maritime patrol aircraft with those of Amphibious Ready Groups and Marine Expeditionary Units (Special Operations Capable) to provide greater combat capabilities to theater combatant commanders.[1]

History

Pre-1990

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. One of these concepts is the Amphibious Ready Group (ARG). The ARG consists of a group of various ships known as an Amphibious Task Force (ATF) and a Landing Force (LF) which normally consists of United States Marines and, on occasion, could consist of United States Army troops.

An ARG is composed of an Amphibious Assault Ship (LHA/LHD), an Amphibious transport dock (LPD) Ship, a Dock Landing Ship (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.

The Navy had two to three ARGs deployed at a given time. Normally one of the ARGs can be found in Mediterranean Sea and Persian Gulf/Indian Ocean area, and the other two in the western Pacific Ocean area.[1]

Early 1990s - Present

In the early 1990s, the 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). The ESG is similar to the ARG except that with the ESG concept, the Navy would be able to deploy almost double the number of independent operational groups, from 19 to 38. In addition, the ESG includes surface warships and submarine escorts, similar to a carrier battle group (now known as a Carrier Strike Group).

An ESG is composed of an Amphibious Assault Ship (LHA/LHD), a Dock Landing Ship (LSD), an Amphibious Transport Dock (LPD), a Marine expeditionary unit, AV-8B Harrier II aircraft, CH-53D Sea Stallion helicopters and CH-46D Sea Knight helicopters. Cruisers, destroyers and attack submarines are deployed with either an Expeditionary Strike Group or a Carrier Strike Group.

As originally envisoned in the 1990s, the ESG concept allowed the Navy to field 12 Expeditionary Strike Groups and 12 Carrier Strike Groups, in addition to surface action groups centered around Iowa class battleships. Thus, the Navy and Marine Corps forces could launch Marines via landing craft and helicopters as warships and submarines struck inland targets with aircraft, missiles and shells. However, defense budget reductions in the mid-1990s, coupled with retirements of older aircraft carriers and amphibious assault ships without one-for-one replacements, has reduced the original 12 x 12 ESG/CSG construct to fewer groups due to fewer ship hulls to support said those groups.[2]

Marine Air-Ground Task Forces

The Marine-Air-Ground Task Forces, or MAGTF, are a combined component of air and amphibious ground forces of the United States Marine Corps. They consist of either the Marine Expeditionary Force (MEF), Brigade (MEB), or the smaller Units (MEU) that deploys either from the United States Navy's Expeditionary Strike Groups or Amphibious Ready Groups.

The MAGTF are composed of four basic elements:
