Topic - Expeditionary Strike Group

The expeditionary strike group (ESG) is a United States Navy concept introduced in the early 1990s, based on the Naval Expeditionary Task Force. The U.S. Navy fields nine expeditionary strike groups and ten carrier strike groups, in addition to surface action groups. ESGs allow the U.S. to provide highly movable and self-sustaining naval forces for missions in various parts of the world. - Source: Wikipedia
