Which fleet was established to control all U.S. naval forces in Europe, including the Normandy cross-channel assault?

• A. Twelfth
• B. Sixth
• C. Seventh
• D. Ninth

Answer: (A)

In World War II the Navy organized its forces by theater, placing all ships, submarines, aircraft, and landing craft under a single fleet for coordinated operations. For Europe, a dedicated command was created to oversee everything across the Atlantic and into the European-African-Middle Eastern theater, ensuring seamless support for the Normandy cross-channel assault.

The Twelfth Fleet was established to control all U.S. naval forces in that European theater, coordinating the naval buildup, convoy protection, naval gunfire support, and the amphibious operations that enabled the D-Day invasion. This centralized command was essential for synchronizing surface ships, submarines, and carrier aviation with the assault forces on the beaches.

The other fleets operate in different theaters or roles: Seventh Fleet covers the Pacific precincts, the Sixth Fleet is associated with the Mediterranean in later years and not the main WWII European invasion command, and the Ninth Fleet served various Atlantic-area and training purposes rather than directing all European naval forces for Overlord.
