'Spartan' is a planned three-stage project that aims to utilize a scramjet to deliver payloads into orbit. It is hoped that the project will allow for the delivery of payloads weighing anywhere between 50 and 100 kg.
The first stage of delivery would involve the use of a reusable rocket booster called the Austral Launch Vehicle. This vehicle would launch vertically and carry the upper stages of a rocket at a speed of Mach five before releasing them at an altitude of 25 km.
This ambitious scramjet project is still in the funding stages, but it is a clear and concerted effort to make inroads into the burgeoning small satellite industry and help smaller countries launch their own satellites.
