In 2002, the Australian Defence Force (ADF) procured a number of APG-73 radars to replace existing radars being used on the FA/18A Hornet platform. The radars were purchased from Raytheon Space and Airborne Systems, the original equipment manufacturer (OEM) based in California, USA. Once the radars were delivered in-country, the Royal Australian Air Force (RAAF) faced the challenge of determining the best way to test and sustain the assets. The RAAF lused a US Navy testing station in Australia as the initial point of testing for all APG- 73 radars. Radars that were deemed unserviceable after local RAAF testing were sent overseas to the OEM for further secondary testing and repair if needed. After a number of years of following this process, the RAAF and OEM found that 60 per cent of assets sent back to the OEM were categorised as “nil fault found”. It was clear that this process for testing and repair was inefficient, inaccurate and costly. The RAAF determined that the major cause of this faulty process was the missing link between the Australian testing station and the OEM’s radar system database. This was a result of the RAAF’s lack of access to the OEM’s intellectual property. Having inaccurate data meant that the assets could not be properly tracked. As a result, the ADF went to tender to find an Australian defence contractor to provide local sustainment services for the APG-73 radar system. Raytheon Australia was awarded the contract to deliver this capability to the ADF, with the project commencing in 2007 after two years of contract negotiations. As part of the contract, Raytheon Australia would deliver deeper maintenance, spares, logistics, engineering, configuration management and obsolescence management for the radar system. One vital aspect of this project was Raytheon Australia’s ability to access intellectual property from Raytheon’s Space & Airborne Systems business unit in order to procure their radar test bench to be used in-country. The procurement of this test bench was central to Raytheon Australia’s solution. This meant that the company’s local team had access to accurate and timely data – critical to the efficient sustainment of the radars.
