DARPA Liberty Lifter Seaplane

The Liberty Lifter program aims to design, build, float, and fly an affordable, innovative, and disruptive seaplane that operates efficiently in ground effect, less than 100 feet above surface.

DARPA Liberty Lifter can sustain flight altitudes up to 10,000 feet mean sea level (MSL), and enables efficient theater-range transport of large payloads at speeds far exceeding existing sea lift platforms.

It will use low cost manufacturing akin to ship fabrication in building a highly innovative seaplane capable of meeting DoD heavy lift requirements (100+ tons) that operates with runway and port independence.
