for the impatient.

Four extreme aviation programs — a Mach 6 hypersonic private jet, a stealth demonstrator, a 14-tonne heavy-lift VTOL and a bespoke twin-engine helicopter. Engineered from the spar up in Sweden.

Hypersonic Private Jet

Hyperion-X Royal

Mach 6. London to Sydney in 2 h 35. Non-stop.

A 44-metre hypersonic private jet for eight — with a master bedroom, wet-room shower and eight-seat club lounge — cruising at Mach 6 and 30,500 m on liquid hydrogen. A single integrated TBCC duct runs the entire underside: turbojet to Mach 2.5, then scramjet to Mach 6. Printed as one continuous PEKK-carbon monocoque, actively cooled by cryogenic LH₂ flowing through micro-channels beneath a zirconium-diboride heat shield. Net-zero CO₂ — the exhaust is water vapour.

Choose an airframe. We begin the build.

Every commission opens with a private technical review in Uppsala. Bring the mission — coast-to-coast in three hours, rooftop-to-rooftop, stealth demonstrator — and we will engineer the aircraft to it.
