The Department of Defense, through the Department of the Navy's NAVSUP Weapon Systems Support, is seeking to procure five units of the Oil Pump Assembly, designated as NSN 7R-2810-014183186-V2. This procurement is critical as the item is flight critical and requires government source approval prior to contract award, with no suitable technical data or manufacturing knowledge available for alternative sources. Interested vendors must be previously approved by the government or submit detailed source approval information along with their proposals, as offers lacking required documentation will not be considered. For further inquiries, interested parties can contact Jake Kucowski at JAKE.KUCOWSKI.CIV@US.NAVY.MIL, and proposals must be submitted within 45 days of the notice publication.
