UK skies protected by C4i Pty Ltd secure voice communication system

C4i Pty Ltd, a Melbourne-based secure voice communications company, has provided its VOICE C2 voice over IP (VoIP) communication system (VCS) for the Ministry of Defence (MoD) Guardian project, providing the UK’s new Air Command and Control System. C4i Pty Ltd, a member of the Frequentis Group since 2021, is subcontractor to IBM. IBM Consulting in the UK are the Prime contractor that is leading the program to develop and install the replacement system

The Guardian project is replacing current systems at RAF bases in the UK with new technology allowing the RAF to enhance its air situation picture in support of continued early detection and rapid response of suspected aircraft threats. Replacing the existing Royal Air Force (RAF) VCS with the new VOIP based system from C4i provides enhanced flexibility, capability and security , as well as reducing overall life cycle costs.

The new system, already in full time operations at RAF Boulmer, will connect the UK’s defence radars and radio network, as well as delivering new capabilities to improve communication and interoperability between UK, NATO and coalition aircraft, which is essential to the protection of the UK’s skies.

“The installation of the UK’s new air command and control system at Boulmer is the first step in this project to deliver enhanced capability to deal with the increased demands of UK airspace and essential surveillance of its skies, supporting the MoD and NATO tasks. We are pleased to be providing the essential communications for the defence of the UK, supporting the transition to digital technologies to support future capabilities,” says Darren Gardner, Managing Director C4i Pty.

Installations for other vital parts of the voice control system are continuing in other locations throughout the UK.
