A comprehensive history of the Sixth Fleet, detailing its role in the Mediterranean from post-World War II through the Cold War to recent conflicts and interventions. The Sixth Fleet has projected the naval power of the United States into the Mediterranean for over 70 years. This work covers the history of the fleet from its inception after the Second World War, through the Cold War, to the War on Terror and the Ukrainian crisis. The Sixth Fleet was created in response to the need for a strong naval force in the Mediterranean Sea to counter the danger posed to the countries bordering the Mediterranean by the naval forces of the former Soviet Union and the Warsaw Pact countries, whose presence threatened the commercial traffic through the Strait of Gibraltar, the Suez Canal, and the Black Sea. In recent decades, several US government departments have considered eliminating the Fleet, but the events in Ukraine in 2022 demonstrated the ongoing need for such a naval force as a deterrent. The book lists most aircraft carriers, battleships, cruisers, destroyers, frigates, submarines, transports, and other support vessels that have been part of the Fleet. It also contains an essential chapter on the US Marine Corps elements, which have always been part of the Fleet. It also describes the aircraft embarked on aircraft carriers and landing ships.

Finally, there is a chapter describing all the Fleet's interventions supporting Allied countries, including interventions in areas affected by natural disasters. The Sixth Fleet is a powerful naval force that has proven its utility as a deterrent.
