Swiss aviation startup  (Zurich, Switzerland) has unveiled the , a hydrogen-powered vertical takeoff and landing (VTOL) aircraft crafted and designed in collaboration with BMW’s (Munich, Germany) creative consultancy Designworks and motorsport engineering company Sauber Group, along with Alfleth Engineering AG and ALD Group.

According to Sirius Aviation’s CEO Alexey Popov, “Sirius Jet undoubtedly incorporates carbon fiber composites in its structure, along with aluminum, titanium alloys and steels. Announcing the exact proportion is premature at this stage, but the share of carbon fiber is quite significant. The fan blades also represent a combination of metals and composite materials.”

The Sirius Jet is a high-performance, zero-emission VTOL aircraft, propelled by a hydrogen-electric propulsion system. Leveraging jet aerodynamics with airplane and helicopter versatility, it achieves extended flight distances, high speeds and high altitudes at near-silent levels.

In 2025, the Sirius Jet will take flight in two versions: the Sirius Business Jet, tailored to private jet needs, and the Sirius Millennium Jet, crafted for commercial aviation. The former will feature a 1,150-mile flight range, cruise speed of 323 miles per hour (mph), altitude capability of 30,000 feet, ultra-quiet noise levels of 60 decibals and will be able to accommodate three passengers. The latter, the Sirius Millenium Jet, offers a 650-mile flight range, cruise speed of 323 mph, altitude capability of 30,000 feet, sound footprint of 60 decibals and will accommodate up to five passengers.
