The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is seeking proposals for the procurement of a flight-critical item identified as NSN 1R-9999-LLHPGL216-V2, with a quantity of one unit required. The procurement is subject to Government source approval prior to contract award, as the technical data available does not support acquisition through full and open competition, necessitating that only previously approved sources be solicited. Interested parties must submit the required documentation for source approval along with their proposals, as offers lacking this information will not be considered. For further inquiries, interested vendors can contact Jake Kucowski at (215) 679-2012 or via email at JAKE.KUCOWSKI.CIV@US.NAVY.MIL, with proposals due within 45 days of this notice.
