Marine One, the presidential helicopter, is transported overseas using large military cargo planes such as the C-17 Globemaster and C-5 Galaxy. These planes can carry several Marine One helicopters along with other essential presidential equipment, including the presidential limousine known as "the Beast." The helicopters are designed to be foldable (especially the VH-60N "White Hawk") for efficient loading onto these transport aircraft. Once the cargo plane reaches the destination, the helicopters are unloaded and prepared for use, ensuring the President always has immediate access to Marine One during overseas travel. This method maintains high mobility and security for the President wherever they travel globally.
