The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is seeking to procure three units of the Rotary Coupler Assembly, identified by NSN 7R-5985-016600367-E7. This procurement is critical as the item is flight critical and requires government source approval prior to contract award, with no available technical data or rights for alternative sourcing. Interested suppliers must be previously approved by the government or submit a comprehensive source approval request along with their proposals, as offers lacking the necessary documentation will not be considered. For further inquiries, interested parties can contact Danielle Diciacco at (215) 697-5970 or via email at danielle.diciacco.civ@us.navy.mil, with proposals due within 45 days of the notice publication.
