The First Navy Jack is believed to have flown aboard the Continental Fleet's flagship Alfred, in January 1776. Commodore Esek Hopkins raised the First Navy Jack to signal his fleet to attack the enemy. In August 1977, the Secretary of the Navy specified that the ship with the longest total period of active service display the First Navy Jack until decommissioned or transferred to inactive service, at which time the flag shall be passed to the next ship in line with appropriate honors. Today, the only US Navy ship authorized to fly the First Navy Jack is the aircraft carrier, U.S.S. Kitty Hawk. However, on May 22, 2002, the United States Navy authorized all ships to display the First Navy Jack flag on their bow at port during the war on Terrorism.
