The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is seeking proposals for the procurement of two units of a flight-critical electrical mounting base, identified by NSN 7R-5975-016112272-P8. This procurement requires government source approval prior to contract award, as the technical data available has not been deemed adequate for full and open competition, meaning only previously approved sources will be considered. Interested vendors must submit detailed information regarding their capability to produce the item, including any prior submissions for source approval, as offers lacking the necessary documentation will not be considered. For further inquiries, interested parties can contact Taylor M. O'Connor at (215) 698-2198 or via email at TAYLOR.M.OCONNOR2.CIV@US.NAVY.MIL, with proposals due within 45 days of the notice publication.
