ORION supports the development and modification of test ranges and training systems, including the next generation Air Combat Training System (P5CTS). P5CTS is a cooperative Air Force/Navy effort to form a common and interoperable training capability. P5CTS enhances worldwide aircrew combat capability and readiness through the acquisition and deployment of superior training instrumentation and will soon include the QF-16 target aircraft. Our support includes technical oversight of the P5CTS Range Instrumentation Waveform, technical oversight of P5CTS Real-Time Operating System (RTOS) upgrade, identification of trends, and recommendation of solutions to address the root cause of failures, and the evaluation of Maintenance Data & Deficiency Reports. In addition, we also provide systems engineering support to nine legacy aerial combat training systems.
