MARINE HELICOPTER SQUADRON ONE (HMX-1)

• Presidential Helicopter Squadron: HMX-1, also known as "Marine One" when the President is aboard, is the exclusive helicopter squadron tasked with the transportation of the President of the United States. • Established in 1947: HMX-1 was activated on December 1, 1947, at Quantico, Virginia, originally to test and evaluate the military potential of helicopters. • First Presidential Flight: The squadron first flew a U.S. President—Dwight D. Eisenhower—in 1957, marking the beginning of helicopter travel for the Commander-in-Chief. • Dual Mission: Aside from presidential transport, HMX-1 also supports operational tests and demonstrations of helicopters, and has a secondary mission of supporting Marines in the National Capital Region. • Call Sign "Marine One": The term "Marine One" refers specifically to any Marine Corps aircraft carrying the President, but is most often associated with HMX-1 helicopters. • Distinctive Green and White Livery: HMX-1 helicopters are known for their unique green and white paint scheme, which has become an iconic symbol of presidential travel. • Fleet of Helicopters: HMX-1 operates multiple helicopter types, including VH-3D Sea Kings and VH-60N White Hawks, and is transitioning to the new VH-92A Patriot. • Highly Selective Squadron: Marines assigned to HMX-1 are meticulously screened for professionalism, appearance, and discretion due to the sensitive nature of their mission. • Stealth and Security Measures: Presidential flights often involve multiple identical helicopters flying in formation to obscure which aircraft the President is aboard, enhancing security. • Historic Operations: HMX-1 has supported numerous historic events, including presidential inaugurations, state funerals, and emergency evacuations, such as during the September 11, 2001 attacks.
