Carry regional freight more cheaply by fitting more cargo in a wing-shaped body, and prove the blended-wing design on a small plane before Natilus attempts an airliner.

Current obstacles
ScheduleFirst flight targeted for 2024, then Q4 2026, now within 24 months of February 2026.
Remote operations approvalFlying cargo with no pilot on board needs regulatory approval that no freighter of this size has yet won.
Physics limits
Lift needs span or speedA short, wide body makes lift less efficiently than a long thin wing, so blended designs win on volume and drag, not necessarily on take-off distance.
How it works
3 parts
Body
Diamond-shaped cargo bay
The cargo hold sits inside the lifting body, fitting more volume than a tube freighter of similar size.
Propulsion
Twin pusher turboprops
Two Pratt & Whitney turboprops push from the rear of the body.
Pilot
Optionally piloted
Designed to fly with a pilot or remotely; early subscale flights showed it stays stable without a complex autopilot.
Natilus is a San Diego startup founded in 2016 that designs blended-wing-body aircraft, where the fuselage itself is shaped like a wing and adds lift. It is building Kona, a regional cargo plane, and designing Horizon, a 200-plus-seat airliner.
Raised a $28M Series A led by Draper Associates in February 2026 to finish the first full-scale Kona.
Claims a 570+ aircraft reservation book worth $24B, mostly Kona; SpiceJet's 100 Horizons depend on certification.
Full-scale Kona first flight has slipped from 2024 to within 24 months of February 2026.
