- Expeditionary Strike Group
The Expeditionary Strike Group (ESG), also known as an "Expeditionary Strike Force", is a military concept which was introduced in the
U.S. military in the early 1990s and is based on the Naval Expeditionary Task Force. The ESG concept allows theU.S. Navy to field 12 Expeditionary Strike Groups and 12 Carrier Strike Groups, in addition to surface action groups. The ESGs allow the naval fleets of the United States Navy to provide highly movable and self-sustaining forces to effectively undertake missions in various parts of the globe.History
Pre-1990
The United States Navy has always been involved in the process of the development of different military concepts which would improve the rapid deployment of naval power and troops from one point to another.Fact|date=July 2008 One of these concepts is the
Amphibious Ready Group (ARG). The ARG consisted 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 ofUnited States Army troops.An ARG is composed of an
Amphibious Assault Ship (LHA/LHD), anAmphibious transport dock (LPD) Ship, aDock Landing Ship (LSD), and aMarine 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 andUH-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 andPersian Gulf /Indian Ocean area, and the other two in the westernPacific Ocean area.cite web|accessdate=2007-05-16

In the early 1990s, the Navy introduced a new concept based on the ARG, the "Naval Expeditionary Task Force" or as it it 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 an
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 attacksubmarines 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. cite web|accessdate=2007-05-16 |url=http://www.globalsecurity.org/military/agency/navy/esg.htm

*USS "Essex" ESG (ESG-FDNF early 2003). The USS "Essex" (LHD-2) is the second ship in the all new "Wasp" class of multipurpose amphibious assault ships and was commissioned on
October 17 ,1992 in San Diego, California. The mission of the "Essex" is to conduct prompt, sustained combat operations at sea, as the centerpiece of the Navy's amphibious strategy, from the Sea.cite web|accessdate=2007-05-26

The "Peleliu" ARG was deployed to thePersian Gulf in 1997 and participated in Exercise Eager Mace 98. cite web |accessdate=2007-05-16

Her design incorporated the best features and capabilities of several amphibious assault ships currently in service. The ship had a well deck for deploying conventional and air cushioned landing craft and a flight deck for launching a variety of helicopters and Harrier jet aircraft. "Belleau Wood" was decommissioned on
October 28 ,2005 and wassunk as part of the Rim of the Pacific (RIMPAC) 06 exercises onJuly 13 ,2006 .cite web|accessdate=2007-05-16

The
22nd Marine Expeditionary Unit , also known as MEU, is a trained, and equipped mobile force of United States Marines that are deployed from self-contained floating sea bases (naval ships) and attached to the ESG.The MEU is composed of four basic elements:
*Command Element - Serves as the headquarters for the entire unit and allows a single command to exercise control over all ground, aviation, and combat service support forces.
*Ground Combat Element - Provides the MEU with its main combat punch. Built around a Marine infantry battalion, the GCE is reinforced with tanks, artillery, amphibious vehicles, engineers, and reconnaissance assets.
*Aviation Combat Element - The ACE consists of a composite medium helicopter squadron containing transport helicopters of various models and capabilities, attack helicopters and jets, air defense teams, and all necessary ground support assets.
*Logistics Combat Element - Providing the MEU with mission-essential support such as medical/dental assistance, motor transport, supply, equipment maintenance, and landing is the mission of the LCE.
The MEU consists of approximately 2,200 Marines and Sailors embarked aboard several amphibious ships.cite web|accessdate=2007-05-16
