The Department of Defense, through the Department of the Navy's NAVSUP Weapon Systems Support, is seeking proposals for the procurement of six units of flight-critical replacement parts, specifically identified by NSN 7R-1377-016098989-P8. The procurement requires government source approval prior to contract award, as the technical data available does not support full and open competition, and only previously approved sources will be considered. Interested vendors must submit detailed information regarding their production capabilities and experience, along with their proposals, to ensure compliance with the Source Approval Information Brochure. For inquiries, potential bidders can contact Timika Nicholson at (215) 697-2582 or via email at TIMIKA.NICHOLSON@NAVY.MIL.
