Answer the following question: Information:  - The United States Naval Academy (also known as USNA, Annapolis, or simply Navy) is a four-year coeducational federal service academy in Annapolis, Maryland, United States. Established on 10 October 1845, under Secretary of the Navy George Bancroft, it is the second oldest of the United States' five service academies, and educates officers for commissioning primarily into the United States Navy and United States Marine Corps. The campus is located on the former grounds of Fort Severn at the confluence of the Severn River and Chesapeake Bay in Anne Arundel County, east of Washington, D.C. and southeast of Baltimore. The entire campus is a National Historic Landmark and home to many historic sites, buildings, and monuments. It replaced Philadelphia Naval Asylum, in Philadelphia, that served as the first United States Naval Academy from 1838 to 1845 when the Naval Academy formed in Annapolis.  - Fort Severn, in present-day Annapolis, Maryland, was built in 1808 on the same site as an earlier American Revolutionary War fort of 1776. Although intended to guard Annapolis harbor from British attack, it never saw action during the War of 1812. The United States Naval Academy acquired Fort Severn and two other military bases from the United States Army on 19 October 1845. The Academy used the structure for classrooms until its demolition in 1909.  - The United States Navy (USN) is the naval warfare service branch of the United States Armed Forces and one of the seven uniformed services of the United States. The U.S. Navy is the largest, most capable navy in the world, with the highest combined battle fleet tonnage. The U.S. Navy has the world's largest aircraft carrier fleet, with ten in service, two in the reserve fleet, and three new carriers under construction. The service has 323,792 personnel on active duty and 108,515 in the Navy Reserve. It has 274 deployable combat vessels and more than 3,700 aircraft in active service .  - Thomas James `` Tom '' Hamilton ( December 26 , 1905 -- April 3 , 1994 ) was an American football player , coach , college athletics administrator , and naval aviator who rose to the rank of rear admiral in the United States Navy . He served as the head football coach at the United States Naval Academy from 1934 to 1936 and again from 1946 to 1947 and at the University of Pittsburgh in 1951 and 1954 , compiling a career college football record of 28 -- 32 -- 1 . Hamilton was also the athletic director at the Naval Academy from 1948 to 1948 and at Pittsburgh from 1949 to 1959 . From 1959 to 1971 , he was the commissioner of the Athletic Association of Western Universities , renamed the Pacific - 8 Conference in 1968 and now known as the Pac - 12 Conference . Hamilton was inducted into the College Football Hall of Fame as a player in 1965 .  - Rear admiral is a naval commissioned officer rank above that of a commodore and captain, and below that of a vice admiral. It is generally regarded as the lowest of the "admiral" ranks, which are also sometimes referred to as "flag officers" or "flag ranks". In many navies it is referred to as a two-star rank (OF-7).  - The United States Armed Forces are the federal armed forces of the United States. They consist of the Army, Marine Corps, Navy, Air Force, and Coast Guard. The President of the United States is the military's overall head, and helps form military policy with the U.S. Department of Defense (DoD), a federal executive department, acting as the principal organ by which military policy is carried out. From the time of its inception, the military played a decisive role in the history of the United States. A sense of national unity and identity was forged as a result of victory in the First Barbary War and the Second Barbary War. Even so, the Founders were suspicious of a permanent military force. It played an important role in the American Civil War, where leading generals on both sides were picked from members of the United States military. Not until the outbreak of World War II did a large standing army become officially established. The National Security Act of 1947, adopted following World War II and during the Cold War's onset, created the modern U.S. military framework; the Act merged previously Cabinet-level Department of War and the Department of the Navy into the National Military Establishment (renamed the Department of Defense in 1949), headed by the Secretary of Defense; and created the Department of the Air Force and National Security Council.  - The University of Pittsburgh (commonly referred to as Pitt) is a state-related research university located in Pittsburgh, Pennsylvania. In 1787 after the American Revolutionary War, it was founded on the edge of the American frontier as the Pittsburgh Academy. It developed and was renamed as Western University of Pennsylvania by a change to its charter in 1819. After surviving two devastating fires and various relocations within the area, the school moved to its current location in the Oakland neighborhood of the city; it was renamed as the University of Pittsburgh in 1908. For most of its history, Pitt was a private institution, until 1966 when it became part of the Commonwealth System of Higher Education.
