President Nixon's visit to Richland, Washington Sept. 26, 1971
VH-3A tail number 150617 on display at the Nixon Library. It was in the Presidential fleet from 1961 to 1976, and often flew as Army One.
Army One is the callsign of any United States Army aircraft carrying the President of the United States. From 1957 until 1976, this was usually an Army helicopter transporting the President. Prior to 1976, responsibility for helicopter transportation of the President was divided between the Army and the U.S. Marine Corps until the Marine Corps was given the sole responsibility of transporting the President by helicopter.
During its presidential service, the helicopter was known either as Marine One or Army One, depending on whether Marine or Army pilots were operating the craft. The helicopter, with seats for sixteen has a seat reserved for the president and the first lady, and single, smaller seats for the two Secret Service agents who always flew with the presidential party.
Wherever the helicopter carrying a US President flies, it is met on the ground by at least one soldier in full dress uniform. An Army aircraft carrying the Vice President is designated Army Two.
^"Airborne Chariots". Wherever 'Marine One' flies, it is met on the ground by at least one US Marine in full dress uniform. In his final days of office, while flying over and landing nearby the Grand Canyon in Arizona, President Bill Clinton was stunned to find a Marine waiting at the landing site ready to salute him.
