fly sustainably without compromise


B1900D-HE Retrofit Product

Available seats: 15
Max payload: 1,500 kg (3,300 lb)
Range at max payload: 800 km (432 nm) +45min IFR
Max cruise speed: 500 km/h (270 kts) at 24,000 ft
Power plant: 2 x 955 kW at 1700 rpm
Entry into service: 2026

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. During the modification, we will inspect and overhaul the airframe and avionics, as well as modernise the interior. Stralis intends to obtain a Supplemental Type Certificate (STC) for this product with CASA and the FAA.

SA-1 Clean Sheet Product

Available seats: approx. 45
Max payload: 5,000 kg (11,000 lb)
Range at max payload: 3,000 km (1620 nm) +45min IFR
Max cruise speed: 580 km/h (313 kts)
Entry into service: 2030

Incorporating learnings from the B1900D-HE program and customer inputs, Stralis will design a clean sheet aircraft optimised around hydrogen electric propulsion. An objective of this program is to offer improved operating costs and scalability.

SA-2 Future Product

Available seats: approx. 90
Max payload: 10,000 kg (22,000 lb)
Range at max payload: > 7,000 km (> 3,780 nm) +45min IFR
Max cruise speed: 700 km/h (375 kts)
Entry into service: 2035

This product will expand our aircraft portfolio and allow us to maximise our impact on aviation carbon emissions. It will compete against conventional regional and narrowbody aircraft in performance and cost.
