The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is seeking proposals for the procurement of two units of a flight-critical item identified by NSN 7R-1680-016216683-EY. The procurement requires that only sources previously approved by the Government be solicited, as the technical data necessary for purchasing or repairing this part is not owned by the Government and cannot be obtained through reverse engineering. This item is essential for maintaining operational readiness, and interested vendors must provide comprehensive documentation for source approval along with their proposals, as failure to do so will result in disqualification. For further inquiries, interested parties can contact Kimberly Flores at (215) 697-6549 or via email at Kimberly.Flores@navy.mil.
