Our first product to market will modify a Beechcraft 1900D by replacing the conventional turbine engine and kerosene fuel system with our novel Hydrogen Electric Propulsion System (HEPS) and liquid hydrogen storage tank. We will inspect and overhaul the airframe and avionics during the modification and modernise the interior. Stralis intends to obtain a Supplemental Type Certificate (STC) with CASA and the FAA for this product.

The SA-1 will be cheaper to operate than a Boeing 737, allowing us to tap into the $2 trillion single-aisle market. Smaller, lower-operating-cost aircraft make new routes viable and reduce door-to-door travel times by flying to underutilised, less congested airports. Incorporating learnings from the B1900D-HE program and customer inputs, Stralis will design a clean-sheet aircraft optimised around hydrogen-electric propulsion. A core objective is to offer improved operating costs and scalability.
