Ten supersonic engines will be launched at Woomera, in outback South Australia, over the next five years in a joint venture between Australia and the United States.

The first scramjet engine was launched successfully last year at Woomera and scientists are now ready for further testing.

Professor Michael Smart from the University of Queensland's research team says the scramjet technology will allow passengers to fly from Sydney to London in two hours, and is all Australian.

"That scramjet that we fly is basically 100 per cent Australian designed, so it's designed at UQ, we've done the testing at UQ in our ground test facility, and then we're going to fly it in Woomera in South Australia, so it's really going to be a very exciting test," he said.
