The Parade of Ships, carrying Navy, Army and Air Force members, opened the 24th annual event, and coincided with a military jet flyover. The ships then docked on Manhattan's West Side and Staten Island.
During the six-day event, the public can enjoy ship tours and performances and activities aboard the Intrepid Sea, Air and Space Museum.
