Cash splash on Australian made 'world leading' drone

But he wouldn't confirm when the aircraft can expect to enter service.

"I'm not going to get ahead of government decision making, but I will say that so far ... they've been hitting every milestone, and we see a definite role for this in the future mix," Mr Conroy said.

Following the first phase of testing's completion, the government is poised to spend about $500 million more on the next stage of the Ghost Bat's development.

The government is preparing to ramp up manufacturing capacity and buy more aircraft in addition to the 11 already purchased.

It is the first combat aircraft to be designed and made in Australia in 50 years, with $1 billion previously committed to its development.

Able to travel at just below the speed of sound, the drone is designed to serve as a "loyal wingman" to help protect and support crewed aircraft carry out a range of activities, including combat roles.

Mr Conroy joined air force chief Air Marshal Stephen Chappell to watch a demonstration of two Ghost Bat uncrewed aircraft at the test range.

The defence industry minister announced the collaborative combat aircraft had successfully completed all of its test activities for 2025, and was four months ahead of schedule.

Asked how he could confidently say the capability was the world's best against Chinese rivals, Mr Conroy replied: "I'm confident that this is world's best capability."

It comes just days after Chinese President Xi Jinping flexed his nation's military might in a parade, showing off missiles, lasers and drones.

Air Marshal Chappell praised partners for working together to produce a "world leading platform".

Australia is seeking to export the uncrewed aircraft to other countries.

Boeing Defence Australia managing director Amy List said there had been interest from international buyers.

"The way the software has been designed and the mission systems have been integrated, means that it is able to evolve with emerging threats," she said.
