The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is seeking proposals for the procurement of 553 units of a nut blank (NSN 1R-5310-017246691-P8) that is classified as a commercial/nondevelopmental/off-the-shelf item. This procurement is critical as the item is flight critical, requiring government source approval prior to contract award, and only previously approved sources will be solicited. Interested vendors must submit the necessary documentation for source approval along with their proposals, as failure to do so will result in disqualification. For further inquiries, interested parties can contact Helen I. Carmelo at (215) 697-1138 or via email at HELEN.I.CARMELO.CIV@US.NAVY.MIL. Proposals must be submitted within 45 days of this notice, and the government reserves the right to proceed with the award based on fleet support needs.
