Hadean and 4C Strategies have successfully integrated a constructive simulation with Exonaut exercise management software, utilising Hadean's spatial computing platform.

The integrated solution, displayed at the International Training Technology Exhibition & Conference (IT²EC) 2024 in London, enabled Hadean's Pattern of Life Indicator (POLI) constructive simulation to be controlled from within 4C Strategies Exonaut software.

Exonaut is widely used in the UK and NATO as an exercise management tool, while constructive simulation is fundamental to effective command and staff training. Integrating the two previously separate functions offers the potential to improve training.

Members of the House Armed Services Seapower and Projection Forces Subcommittee raised concerns about the proposed US Navy (USN) plan to pare down key shipbuilding programmes on 17 April during the subcommittee hearing on the USN's Fiscal Year (FY) 2025 budget request.

While the USN – as was the case with the rest of the Pentagon – was charged with keeping a lid on costs, lawmakers said they felt the USN went too far with some major programmes.

Connecticut Congressman and ranking member of the Seapower and Projection Forces Subcommittee, Joe Courtney, set the tone with his opening statement.

“The Fiscal Responsibility Act (FRA), which [was] passed in May 2023 to avert a default on the full faith and credit of our nation's currency and bonds, mandated a 1% increase in the Department of Defense's budget request for fiscal year 2025,” Courtney said.

The first of three prototypes to be built under Australia's Ghost Shark extra-large autonomous undersea vehicle (XL-AUV) programme has been completed, the country's Minister for Defence Industry Pat Conroy announced on 18 April.

The programme to develop the XL-AUV is being jointly developed and funded by a partnership between the Australian Department of Defence and Anduril Australia, a subsidiary of US defence technology company Anduril Industries.

Also working in collaboration with this partnership is a team from the Royal Australian Navy (RAN).

The Ghost Shark programme aims to develop a long-range AUV capability for the RAN's persistent intelligence gathering, surveillance, and remote strike requirements.

At a media event to disclose further details of the Ghost Shark programme, Conroy described the first prototype of the XL-AUV as a “combat-ready drone”.

“This drone is capable of doing intelligence-gathering, surveillance, and reconnaissance and, importantly, delivering strike. So it has the ability to be fitted with weapons to deter potential aggressors”, Conroy added, without providing further details.
