The Department of Defense, through the Department of the Navy's NAVSUP Weapon Systems Support, is seeking proposals for the procurement of window washer pumps, specifically NSN 7R-1680-145678340-P8, with a quantity of four units required for delivery FOB origin. This procurement is critical as the item is flight critical, necessitating Government source approval prior to contract award, and only previously approved sources will be considered for this solicitation. Interested vendors must submit the necessary technical data and source approval documentation alongside their proposals, as failure to do so will result in disqualification. Proposals are due within 45 days of the notice publication, and inquiries can be directed to Kelly A. Gipson at (215) 697-4787 or via email at KELLY.A.GIPSON1@NAVY.MIL.
