The first stage is powered by four Sirius engines in the first-stage, a single Sirius engine in the second-stage, and a single Pheonix engine in the third-stage. Both the launcher and the engines are produced in-house by Gilmour Space Technologies. The initial Block 1 variant is expected to be replaced by a more-powerful Block 2 variant.
This is Australia's locally-produced and launched orbital launcher. It's first launch is planned for the first-half of 2024, perhaps as soon as April - depending on the outcome of initial dress-rehearsals.
