Development of a test program set on the consolidated automated support system for a redesigned AN/APG-73 radar receiver shop Replaceable Assembly

Abstract

Raytheon Canada Limited (RCL) supports the Royal Canadian Air Force (RCAF) by providing comprehensive, in country maintenance and support of the AN/APG-73 Radar System for the CF-18 Hornet aircraft. As part of a midlife upgrade to the CF-18 aircraft, the RCAF replaced the AN/APG-65 Radar with the AN/APG-73 Radar. The RCAF chose the Consolidated Automated Support System (CASS) to support the Radar Receiver (RR). 2 RF CASS stations and 2 sets of radar Operational Test Program Sets (OTPS) were provided to RCL to support the equivalent of second line and depot level support for the RR. The AN/APG-73 RR supplied to the RCAF is a later configuration than the majority of the fielded systems with the United States Navy (USN) and other Foreign Military Sales (FMS) customers; specifically there are 2 Shop Replaceable Assemblies (SRA) that were redesigned due to obsolescence. (Note: The Royal Australian Air Force (RAAF) also has this newer configuration.) Although these newer SRAs are form, fit and functional equivalents to the older versions, they have a different board layout and components and require a different test program at the SRA level.
