"Uniting to strengthen Australia" 

• As a supplier to Lockheed on the Air6500 Project, C4i will provide its VOICE C2 solution ensuring secure communications across air, land, sea, and space
• Project for Royal Australian Airforce (RAAF) aims to enhance security, rapid response, and interoperability of the country’s defence systems
• System will bridge classified and non-classified networks to connect systems, strengthen decision-making, and counter modern threats

AIR6500 is the RAAFs multibillion-dollar plan for an integrated communication network promoting seamless operability and connectivity across sensors, weapons, jets, and warships to protect against threats. Lockheed Martin was selected to lead the project in late August 2023, contracting 10 leading-edge Australian companies to support this mission.

As a supplier to Lockheed, Australian defence company, C4i, a member of the Frequentis Group, will provide its secure VOICE C2 technology. This secure communication system acts as a bridge, linking operators, radios, and telephony across the RAAF's operations. This integration will enhance the RAAF's ability to respond effectively in high-pressure situations.

Melbourne-based critical communications SME, C4i, has been awarded a nationwide voice communication control system (VCCS) contract. Following a successful initial system delivery on behalf of C4i, this contract will expand on what is already one of the largest systems in Asia Pacific.

C4i’s secure VCCS, the VOICE C2 system, offers unparalleled operational flexibility, allowing operators to control any radio – from anywhere – at any time; with the intuitive graphical user interface providing operational access to both local and remote systems, for quicker response times. 

With several hundred controller working positions, working end-to-end, the C4i VCCS will represent one of the largest Voice Over Internet Protocol (VoIP) systems in Asia Pacific and the world.

Lockheed Martin Australia has joined forces with C4i, Australian secure communications systems expert, signing a contract as part of a proposal to deliver advanced secure communication capabilities to support the Royal Australian Air Force’s AIR6500 Phase 1 Project (AIR6500-1).

The contract will see the two companies work together to design, test, integrate and authenticate secure voice communication technologies as part of the risk reduction phase in transitioning to Lockheed Martin Australia’s proposal for AIR6500-1 acquisition.

The secure communications systems technologies will focus on homegrown secure voice communication systems that connect into next generation Joint Air Battlement Management C2 networks, while increasing system security, rapid response and interoperability in support of the RAAF’s Integrated Air and Defence Missile (IAMD) mission.

Australian based company, C4i, welcomed Mr. Josh Burns, Federal MP for Macnamara to its facilities  to showcase first hand C4i’s high-end C4i defence secure communication technology. The products  are all designed, developed and built in Melbourne in the centre of his Federal Electorate.

In 2021 C4i received AU$33.6M of export orders, directly contributing to the local economy, securing over 95 high-end engineering jobs in the defence industry and its associated supply chain in the Melbourne/Victoria area. The Frequentis Group intends to create additional job growth in Melbourne by transferring software and hardware Intellectual Property from Europe to Australia, further developing C4i as a global export hub for Air Defence communication technology.

Melbourne-based secure communications company achieves historical export orders
