The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is seeking to procure two units of the flight-critical item identified by NSN 7R-1560-016951459-RQ, with reference number 3671230S01003-5TSP. Due to the lack of available technical data and the necessity for Government source approval prior to contract award, only previously approved sources will be solicited for this procurement. The item is essential for maintaining operational readiness, and 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 Alainna M. Pettit at (215) 697-2606 or via email at ALAINNA.PETTIT@NAVY.MIL, with a proposal submission deadline of 45 days from the notice publication date.
