DARPA ends cargo seaplane program, eyes new uses for tech
The Defense Advanced Research Projects Agency has ended its experiment to create a heavy cargo seaplane.
The nearly three-year-old Liberty Lifter program was intended to design and build — and possibly float and fly — a long-range, low-cost seaplane that could take off and land in rough seas. DARPA said in 2023 that it wanted the plane to have roughly the same size and capacity as a C-17 Globemaster, which can carry more than 170,000 pounds of cargo such as M1 Abrams tanks.
In a statement to Defense News, DARPA confirmed it had concluded the Liberty Lifter program in June. Aviation Week first reported the ending of the Liberty Lifter program.
“We’ve learned we can build a flying boat capable of takeoff and landing in high sea states,” program manager Christopher Kent said. “The physics make sense. And we’ve learned we can do so with maritime building techniques and maritime composites.”
But DARPA said it will not move forward with building an aircraf..
