The Department of Defense, specifically the Naval Air Systems Command (NAVAIR), intends to award a contract to Raytheon BBN Technologies Corporation for the development and enhancement of the Ground Replay System (GRS) engineering tool, which is critical for high-fidelity mission reconstruction of P-8A sorties. The primary objective of this procurement is to expand the GRS to support new Air Anti-Submarine Warfare (ASW) capabilities, particularly in coherent processing and displays necessary for Multi-static Active Coherent Enhancements (MAC-E) and UnderSea Advantage (USA) Post Flight Analysis (PFA). This contract is vital for maintaining and improving the GRS, as Raytheon BBN is the sole source with the proprietary technical data and expertise required for this effort. The planned award is expected in the third quarter of FY25, with a performance period of five years, and interested parties can reach out to Diane McCauley or Gina Bailey for further information at their respective email addresses.
