The Department of Defense, specifically the Naval Air Warfare Center Training Systems Division (NAWCTSD), intends to procure two proprietary Gateway Manager (GWM) devices configured for the Aegis Ashore Team Trainer (AATT) Program, utilizing Windows 11. This procurement is being conducted on a sole-source basis with Northrop Grumman, the original manufacturer, due to their unique technical expertise and proprietary data necessary for the development of these devices. The GWM units are critical for maintaining the operational effectiveness of the AATT training system, which supports the United States Navy's training requirements. Interested parties must submit their technical capabilities by September 11, 2024, to Valentina Walsh and Dean DeFord via email, as the government will not pay for any information submitted in response to this notice.
