The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support Mechanics, is seeking to procure 10 units of the Expansion Joint AY, identified by NSN 3H-2825-017186624-PP. This procurement is critical as the government does not possess the data or rights necessary to purchase or contract repair of this part from alternative sources, making it uneconomical to reverse engineer. Interested parties are encouraged to submit their interest and capability statements within 45 days of this notice, as the government intends to negotiate with only one source under FAR 6.302-1. For further inquiries, potential vendors can contact Alison E. Harper at (717) 605-4443 or via email at ALISON.E.HARPER.CIV@US.NAVY.MIL.
