Sirius Aviation, now known as Stellar Aircraft, is set to reveal its hydrogen-powered business jet demonstrator in June 2025 from its new United States headquarters. This follows the introduction of the Sirius Jet concept, hailed as the world's first hydrogen-powered vertical take-off and landing aircraft. Designed in partnership with BMW's Designworks and Sauber Group, the aircraft will offer three- or five-passenger variants with a cutting-edge hydrogen-electric propulsion system. CEO Alexy Popov expressed the company's ambition to redefine sustainable aviation through revolutionary technology. Stellar Aircraft's manufacturing of the Stellar Jet is underway, with a focus on a proprietary hydrogen fuel tank surpassing industry standards. While the Swiss office remains pivotal for operations and collaboration, the shift to the US is seen as a strategic move to leverage opportunities in the American market. The rebranding to Stellar Aircraft signifies a new chapter for the company, aligning with its vision for innovation and leadership in the aviation sector.
