AUSROC II-2

On Thursday 22nd October 1992 the AUSROC II rocket vehicle failed in its maiden launch attempt at the Woomera Rocket Range in South Australia. Whilst the launch attempt was a failure, the program as a whole was regarded to be a great success. AUSROC II was the largest liquid fuelled rocket to be designed and built in Australia and done so by an amateur group of engineers, scientists, technicians and enthusiasts.

Following the failed launch attempt, a decision was made by the AUSROC Program Group to build a second AUSROC II vehicle to be known as AUSROC II-2. The AUSROC II-2 vehicle will essentially be a revised and improved AUSROC II. Design elements that caused the failure of the AUSROC II launch attempt were isolated and a redesign of components and system layouts has been undertaken by the new AUSROC II-2 project team.
