Can marine one land on water?

No, Marine One, the call sign for the helicopter carrying the President of the United States, cannot land on water. It is a Sikorsky VH-3D Sea King or a newer model VH-60N White Hawk helicopter, both of which are designed for land-based takeoff and landing. These helicopters do not have the capability to float or land on water like a seaplane or amphibious aircraft.
