The Liberty Lifter is a project to develop an inexpensive seaplane that has the cargo volume of a C-17 Globemaster.


  1. The ‘X-plane’ achieves bulk lift by using wing-in-ground effect.
  2. The wing-in-ground effect provides additional lift by exploiting air trapped between the wings and the surface of the sea.
  3. The aircraft is said to have a range of 6,500 nm (12,000 km).
