The Department of Defense, through the Department of the Navy's NAVSUP Weapon Systems Support, is seeking proposals for the procurement of four window washer pumps, identified by NSN 7R-1680-145678340-P8 and reference number 218363. The 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 this solicitation. Interested vendors must submit the necessary technical data and source approval documentation with their proposals, as failure to do so will result in disqualification. Proposals are due within 45 days of the notice publication, and interested parties can contact Kelly A. Gipson at (215) 697-4787 or via email at KELLY.A.GIPSON1@NAVY.MIL for further information.
