Aviation News – REGENT announced on September 2, 2026, that it has successfully completed the first crewed flight of its Viceroy wing-in-ground seaglider, marking a historic leap for zero-emission coastal transportation.
The landmark test flight establishes the REGENT Viceroy as the largest-ever all-electric wing-in-ground-effect (WIG) craft to take flight with humans onboard. Engineered to transport up to 12 passengers at skimming speeds reaching 180 mph (289 km/h), the zero-emission vessel operates entirely over maritime environments. The successful achievement moves the program significantly closer to commercial deployment for regional coastal transportation networks.
While larger crewed experimental ground-effect craft—known as ekranoplans—were operated by the Soviet Union in the 1970s, those historical platforms relied on conventional fossil-fuel powerplants and served strictly military objectives. By contrast, REGENT’s modern approach leverages modern electric propulsion and advanced automated control systems designed specifically for high-speed, eco-friendly civilian and defense transport.
The flight relies on the physical phenomenon known as ground effect, where aerodynamic drag decreases substantially when an aircraft flies close to a fixed surface. Operating within one wingspan of the water’s surface creates a cushion of high-pressure air beneath the hull, drastically increasing lift and overall energetic efficiency. This mechanism enables the all-electric seaglider to dramatically expand battery range while maintaining high cruise speeds over long coastal routes.
“Completing our first human-crewed flight is an extraordinary testament to our engineering team and validates the immense potential of seaglider technology,” stated a representative following the flight milestone. “This achievement proves that high-speed, zero-emission maritime transit is no longer a future concept, but a operational reality.”
The successful human-crewed flight paves the way for advanced flight testing regimes, commercial certification, and series production. As REGENT continues scaling its seaglider platform, the technology promises to redefine high-speed ferry operations, island hopping, and regional coastal logistics through low-cost, zero-emission air mobility.
