From quarter-scale prototype to world's largest all-electric flying machine

We proved the technology with our quarter-scale seaglider prototype in 2022.

Now, we're undertaking sea trials of the full-scale, 15,000lbs Viceroy seaglider prototype, drawing on the key lessons learned from the smaller prototype and pushing the limits of all-electric flight.

When the full-scale prototype flies this summer it will be the largest-ever all-electric flying machine.
