MELBOURNE, 21 March 2025: Frequentis C4i is proud to announce that it has been under contract for over eight months to provide cutting-edge multi-domain communication systems for the Australia Defence Force’s (ADF) next-generation AIR6500 Joint Air Battle Management System. C4i’s partnership with Lockheed Martin Australia represents a significant milestone in the company’s ongoing collaboration, building on the success of initial capability demonstrations.

Under the contract, C4i is developing sovereign voice communication systems with a built-in intuitive Human Machine Interface that will connect into Joint Air Battlement Management C2 networks. A team of 15 engineers are dedicated to designing, building and testing the voice communication systems within C4i’s technology lab headquarters in Melbourne.

The AIR6500 program is a key element of the ADF’s national security strategy, enhancing capabilities across air, land, sea, cyber, and space. Frequentis C4i’s innovative technology will serve as the backbone of these efforts, enabling secure, real-time communications critical for joint force operations.

“By integrating our advanced hardware and software solutions, we are enhancing the ability of the military to communicate securely and effectively across all domains. This capability is vital for responding to threats quickly, especially in challenging environments,” said Darren Gardner, Managing Director, Frequentis C4I.

“Lockheed Martin is actively showcasing Australia’s next-gen air battle management technology on the world stage, positioning C4i technology as a key element in international defence initiatives.”

“As an SME in Australia, we are proud to be contributing to a major Australian Defence program which has meant we are adding more highly skilled engineers to the team each year.”

In addition to bolstering Australia’s defence capabilities, this collaboration will open up new export opportunities for C4i to participate in global defence projects. Lockheed Martin Australia is drawing on the best of Australian industry to deliver AIR6500, which has the potential to provide a pipeline into the global integrated air and missile defence market estimated to be worth AUD$83B.

“We are delighted to partner with C4i to integrate innovative voice communication technologies into AIR6500,” said Rob Milligan, Program Director AIR6500, Lockheed Martin Australia.

“C4i brings a wealth of experience to AIR6500. Their robust, secure technologies are highly established and operated by defence, governments and industry in over 40 countries. This partner integration will enhance the ADF’s ability to respond effectively in high-pressure situations.”

The scalable and rapidly deployable communication systems from C4i will strengthen key military alliances, ensuring seamless collaboration during joint operations. This highly mobile solution empowers defence personnel to establish Joint Operational Centres quickly, providing a robust communication infrastructure for coordinated responses in complex scenarios.
