AUSROC 2.5 is a bi-propellant Liquid Oxygen and Kerosene sub-orbital rocket, with a flight mass of 350 to 400 kg.

The AUSROC 2.5 motor will have the same dimensions and geometry as the AUSROC III motor, but is ablative rather than regeneratively cooled.

We are currently seeking universities and volunteers to work on the AUSROC 2.5 project. Please click here for more information.
