This Sikorsky VH-92A is currently undergoing testing by the US Marine Corps as an expected replacement for Marine One, the helicopter used by Marine Helicopter Squadron One (HMX-1) to ferry the US president. The VH-92A has been flying over Washington, D.C., recently as part of the test flights and will make its public debut during the Salute to America festivities over the National Mall on July 4.
During the celebration, the VH-92A will participate in a fly-over with a Boeing 747 that is used as Air Force One and a Sikorsky VH-3D helicopter that is used as Marine One. The call signs Marine One and Air Force One are only used for the aircraft when the president is on board; the aircraft use different designations when not flying the president.
The Salute to America is scheduled to begin about 6:15 pm (EDT) and will include several other helicopters as well. The US Coast Guard is expected to fly Sikorsky H-60 and H-65 helicopters, and the US Army will operate four Boeing Apache helicopters. In addition to the helicopters, the US Navy will provide F-18s and two FC-35s, the US Air Force will fly a B-2 bomber and two F-22 fighters, and the Coast Guard will fly an HC-130 airplane.
