Navy One is the call sign of any United States Navy aircraft carrying the President of the United States. There has only been one such aircraft: a Lockheed S-3 Viking, BuNo 159387, assigned to the "Blue Wolves" of VS-35, which transported President George W. Bush to the aircraft carrier USS Abraham Lincoln off the coast of San Diego, California on May 1, 2003. The pilot was Commander Skip Lussier, then VS-35's executive officer; and the flight officer was Lieutenant Ryan Phillips.
That S-3 was retired from service and placed on display at the National Naval Aviation Museum in Pensacola, Florida on July 17, 2003.
A Navy aircraft carrying the Vice President would be designated Navy Two.
