The Department of Defense, through the Department of the Navy's NAVSUP Weapon Systems Support, is seeking proposals for the procurement of FMS spares in support of the F-18 Aircraft, specifically for the rudder component (P/N: 74A240300-1023, NSN: 1RM 0000 LLW79D334 QE) with a quantity of six units. These items are critical for flight operations, necessitating government source approval prior to contract award, as the technical data available does not support full and open competition. Interested vendors must provide the required documentation for source approval as outlined in the NAVSUP WSS Source Approval Information Brochure, and offers lacking this information will not be considered. For inquiries, contact Kate Hull at (215) 697-6646 or via email at kathryn.s.hull.civ@us.navy.mil.
