An unmanned spy plane using technology developed by Rolls-Royce has made its first flight.

Mantis, BAE Systems' next-generation autonomous system, made its maiden flight in Woomera, South Australia and has now successfully completed a series of trials. The Mantis programme is jointly funded by UK MOD and UK industry.

Rolls-Royce has worked in conjunction with BAE Systems to lead the development of an integrated power system (IPS), which involves the twin engines and propellers and associated sub-systems.

The Rolls-Royce IPS, which was designed and assembled in Bristol by a team of around 50 specialists, includes the twin engines, intake and exhaust systems, engine cowls, mounting structure and oil system.

Martin Fausset, Rolls-Royce managing director of Defence Aerospace, said: "Mantis has enabled Rolls-Royce to demonstrate its capability to move beyond basic engine supply and deliver an integrated power system in a short timeframe."

Rolls-Royce designs power systems for other unmanned planes, including the Global Hawk, Fire Scout and nEUROn demonstrator programmes.
