The Department of Defense, through the Department of the Navy's NAVSUP Weapon Systems Support, is seeking proposals for the procurement of 32 units of follower gear and other replacement parts, identified by NSN 1R-1680-016216738-EY. This procurement requires engineering source approval due to the critical nature of the part, necessitating that only approved sources may supply the item, as the Government lacks sufficient data to source it from alternative suppliers. Interested vendors must submit their qualifications and any required documentation for source approval, as proposals will only be considered from those who meet the established criteria. For further inquiries, Kristin Clemens can be contacted at (215) 697-3814 or via email at KRISTIN.CLEMENS2.CIV@US.NAVY.MIL, with a proposal submission deadline of 45 days from the notice publication date.
