The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is seeking to procure 100 units of a pressure sensor, identified by NSN 1H-6685-015995183-X3. This procurement is critical as the sensor is essential for measuring and controlling pressure, temperature, and humidity, which are vital for various defense applications. The government intends to solicit and negotiate with only one source due to the proprietary nature of the data required for this part, making it uneconomical to reverse engineer. Interested parties are encouraged to express their interest and capability within 45 days of this notice, and all inquiries should be directed to Collin A. Browning at (564) 226-1306 or via email at COLLIN.A.BROWNING.CIV@US.NAVY.MIL.
