The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support Mechanics, is seeking to procure 10 units of an ambient temperature sensor for repair and modification purposes. This procurement is critical as the government does not possess the data or rights necessary to contract the repair from alternative sources, making it uneconomical to reverse engineer the part. Interested vendors are encouraged to express their interest and capabilities within 45 days of this presolicitation notice, with the primary contact for inquiries being Helen I. Carmelo at (215) 697-0000 or via email at HELEN.I.CARMELO.CIV@US.NAVY.MIL. The contract will be awarded only to qualified sources, and proposals will be considered based on the government's discretion regarding competitive procurement.
