The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is seeking to procure 61 units of a photo sensor identified by NSN 1H-5985-015995173-X3. The procurement is intended to fulfill a requirement for supplies that will be solicited and negotiated with only one source, as the government does not own the rights to the data necessary for alternative sourcing, making reverse engineering uneconomical. This equipment is critical for various defense applications, and the delivery locations include DLA Distribution in New Cumberland, PA, and DLA Distribution San Joaquin in Tracy, CA. Interested parties are encouraged to express their interest and capabilities within 45 days of this notice, and all inquiries should be directed to Amber C. Long at (717) 605-4657 or via email at AMBER.LONG@NAVY.MIL.
