The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is seeking to procure 10 units of a flight-critical item identified by NSN 7R-1680-016216683-EY, with reference number M359-1-0-2-1-1. This procurement is intended to be negotiated with only one source due to the specialized nature of the item, which requires Government source approval prior to contract award, as the technical data available is insufficient for full and open competition. Interested parties must demonstrate their capability to meet the requirements and submit necessary documentation for source approval, as offers lacking the required data will not be considered. For further inquiries, Alexis K. Healy can be contacted at (215) 697-1143 or via email at ALEXIS.HEALY@NAVY.MIL.
