Coast Guard One would be the air traffic control call sign of any United States Coast Guard aircraft carrying the President of the United States. Similarly, any Coast Guard aircraft carrying the Vice President is designated Coast Guard Two.
As of 2016[update], there has never been a Coast Guard One flight. Coast Guard Two was activated on September 25, 2009, when Vice President Joe Biden took a flight on CG 6019, an HH-60 Jayhawk helicopter, over the recently flooded Atlanta area.
The Commandant of the Coast Guard often travels aboard a Gulfstream C-37A aircraft whose standard callsign is "Coast Guard Zero One". The aircraft is stationed at USCG Air Station Washington, D.C.
