FREQUENTIS C4i and Lockheed Martin unite to strengthen Australian national security

FREQUENTIS C4i and Lockheed Martin unite to strengthen Australian national security

  • 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.

C4i’s secure VCCS, the VOICE C2 system

Australian SME and defence exporter C4i Pty Ltd awarded nationwide air defence communication contract in Asia Pacific

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.
