The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is seeking to procure three units of the GOV Valve Bonnet, identified by NSN 1H-2825-014815029-X6. This procurement is critical as the Government intends to solicit and negotiate with only one source due to the proprietary nature of the data required for the purchase or repair of this part, which cannot be reverse-engineered economically. Interested parties are encouraged to express their interest and capability to meet the requirement within 45 days of this notice, with the understanding that the Government may choose not to compete based on the responses received. For further inquiries, interested vendors can contact Melissa A. Furness at (771) 229-0075 or via email at MELISSA.FURNESS@NAVY.MIL.
