The United States Navy

Notable sailors
Many past and present United States historical figures have served in the Navy. Notable officers include John Paul Jones, John Barry (Continental Navy officer and first flag officer of the United States Navy), James Lawrence (whose last words "don't give up the ship" are memorialized in Bancroft Hall at the United States Naval Academy), Stephen Decatur, Jr., David Farragut, David Dixon Porter, Oliver Hazard Perry, Commodore Matthew Perry (whose Black Ships forced the opening of Japan), and Chester Nimitz, Admiral of the Pacific Fleet in World War II.
A number of presidents served in the Navy before their political careers, including John F. Kennedy (who commanded the famous PT-109), Lyndon B. Johnson, Richard Nixon, Gerald Ford, Jimmy Carter, and George H.W. Bush. Both Theodore Roosevelt and Franklin D. Roosevelt were the Assistant Secretary of the Navy prior to their presidencies. Many members of Congress served in the Navy, notably U.S. Senators Bob Kerrey, John McCain, and John Kerry. Other notable former members of the U.S. Navy include astronauts, entertainers, authors, and professional athletes such as David Robinson and Roger Staubach.
