WASHINGTON, D.C. - The U.S. military's experimental Liberty Lifter heavy cargo seaplane program has a new sole contender: Aurora Flight Sciences. The Defense Department awarded Aurora an $8.3 million contract extension to continue developing its design after competitor General Atomics' proposal was dropped.
DARPA, the Pentagon's research arm, originally envisioned a Liberty Lifter rivalling the massive C-17 Globemaster in size. However, the project has been scaled back to roughly a C-130 Hercules for the demonstrator phase, with potential for future expansion based on success.
General Atomics proposed a unique twin-hull design for water stability, while Aurora's concept resembles a traditional flying boat with a single hull and high, angled wings. Aurora's latest iteration moves the floats to the wingtips and incorporates a new pi-shaped tail design for better cargo door access.
According to DARPA, General Atomics' design couldn't meet the program's ambitious goals and tight timelines. Aurora, on the other hand, impressed with its adherence to the aggressive schedule and technical requirements.
Aurora, partnered with shipyard ReconCraft and naval engineering firm Gibbs & Cox, will undergo a preliminary design review in early 2025. A successful review will lead to further design refinement, construction, and ultimately a first flight targeted for late 2027 or early 2028.
