Hensoldt has installed an air traffic control (ATC) sensor at the Australian Defence Force's (ADF's) Army Aviation Centre Oakey in Queensland.

The sensor – delivered as part of the Department of Defence's (DoD's) Project Air 5431 Phase 2 – has achieved initial operational capability (IOC), Hensoldt said in a media release on 25 June.

Project Air 5431 Phase 2 aims to replace the ageing ATC sensors of the ADF with nine new fixed ATC sensors and three independent Automatic Dependent Surveillance-Broadcast (ADS-B) ground stations.

β€œThe [new] sensors [will] provide surveillance coverage for fixed-base flying operations,” Hensoldt said.

Hensoldt is providing its Airfield Surveillance Radar – Next Generation (ASR-NG) systems to the ADF under Project Air 5431 Phase 2, the DoD said.

According to Hensoldt, the ASR-NG is a multibeam 3D S-band solid-state approach that controls primary and secondary surveillance radar. The radar can detect aircraft that are at a distance of up to 120 n miles and an altitude of 50,000 ft. The radar can also provide 3D height information of non-cooperative targets, clutter cancellation, and wind farm mitigation.

The radar operates within a frequency range of 2,700–2,900 MHz for surveillance. The radar is also integrated with the identification friend-or-foe (IFF) Mode 5 system operating on 1,030 and 1,090 MHz.

The DoD said Hensoldt delivered two ASR-NG systems at Royal Australian Air Force (RAAF) Base Williamtown and Army Aviation Centre Oakey at the end of 2023. The company is expected to deliver four ASR-NG systems in 2024 at RAAF bases Amberley, East Sale, and Tindal, and Naval Air Station Nowra.
