The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is seeking proposals for the procurement of 630 units of the Filter Element, Fluid (NSN 1R-1650-016743164-TX, REF NR CS-24-100-200G). This item is classified as flight critical, necessitating government source approval prior to contract award, as the technical data available does not support full and open competition. Interested vendors must provide comprehensive documentation as outlined in the NAVSUP WSS Source Approval Information Brochures, and failure to submit the required data will result in disqualification from the award process. For further inquiries, interested parties can contact Christophe J. Ammerman at (215) 697-5047 or via email at CHRISTOPHER.AMMERMAN@NAVY.MIL.
