The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is seeking to procure 14 units of a pressure gauge (NSN 1H-6685-007995783-X5) under a presolicitation notice. The procurement is intended for a specific part for which the Government does not own the necessary data or rights for alternative sourcing, making it uneconomical to reverse engineer or purchase data from other sources. Interested parties have 45 days to express their interest and capability to fulfill this requirement, although the Government reserves the right to proceed with a sole-source contract under FAR 6.302-1. For further inquiries, potential vendors can contact Melissa A. Furness at (771) 229-0075 or via email at MELISSA.FURNESS@NAVY.MIL.
