The Department of Defense, through the Department of the Navy's NAVSUP Weapon Systems Support, is seeking proposals for the procurement of a support frame and other replacement parts, specifically identified by NSN 7R-1680-016755099-SX and reference number 3305AS349-2. This procurement requires government source approval prior to contract award due to the flight-critical nature of the item, and only previously approved sources will be considered for solicitation. Interested vendors must submit comprehensive documentation as outlined in the NAVSUP Source Approval Information Brochures, and failure to provide the necessary data will result in disqualification from the award process. For further inquiries, interested parties can contact Connor C. Lewis at (215) 697-4757 or via email at CONNOR.C.LEWIS.CIV@US.NAVY.MIL.
