Commissioning Pennants

The U.S. Navy commissioning pennant is the distinguishing mark of a commissioned Navy ship. The pennant is a long streamer in the colors of the Navy. Blue at the hoist, with seven white stars and a single longitudinal stripe of red and white. The pennant is flown at all times as long as a ship is in commissioned status, except when a flag of an officer or civilian official is on board and flies his personal flag in its place.
