United States Second Fleet
Updated: Wikipedia source
The United States Second Fleet is a numbered fleet in the United States Navy responsible for operations in the East Coast and North Atlantic Ocean. Established after World War II, Second Fleet was deactivated in 2011, when the United States government believed that Russia's military threat had diminished, and reestablished in 2018 amid renewed tensions between NATO and Russia. Second Fleet's area of responsibility includes about 6,700,000 square miles (17,000,000 km2) of the Atlantic Ocean from the North Pole to the Caribbean and from the shores of the United States to the middle of the Atlantic Ocean. Second Fleet's United States West Coast counterpart was United States First Fleet from the immediate post-World War II years until 1973, and United States Third Fleet from 1973. In 2011, Second Fleet oversaw about 126 ships, 4,500 aircraft, and 90,000 personnel homeported at U.S. Navy installations along the United States East Coast.
