The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is seeking proposals for the procurement of 135 units of a specific bushing component, identified by NSN 1R-1650-016633738-H5 and reference number NAS73-9E013. This requirement is classified as sole source, indicating that the government lacks sufficient data to contract with any source other than the current supplier, highlighting the critical nature of this component in aircraft hydraulic, vacuum, and de-icing systems. Interested vendors must obtain Government Source Approval prior to award, and proposals must include the necessary documentation as outlined in the NAVSUP WSS Source Approval Brochure, which can be accessed online. For further inquiries, potential bidders should contact Casey M. Brown at casey.m.brown20.civ@us.navy.mil or by phone at (215) 697-3752.
