The Department of Defense, specifically the Naval Air Warfare Center Aircraft Division, is seeking to procure a Radar Signal Simulator for the H-60 Aircraft to support Foreign Military Sales programs for the Spanish Armada and the Norwegian Defence Materiel Agency. The contract will be awarded on a sole source basis to Symetrics Industries, LLC (dba Extant Aerospace), as they are the only entity with the proprietary data and expertise necessary to manufacture the simulator. This procurement is critical for ensuring the operational readiness and effectiveness of the H-60 aircraft in international defense collaborations. Interested parties can direct inquiries to Tammy Fossa at tamara.d.fossa.civ@us.navy.mil, noting that this notice is not a request for competitive proposals and the Government will not pay for any responses received.
