The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is seeking to procure two units of the Wing Assembly, Aircr, identified by NSN 7R-1560-016002718-QE. This procurement requires engineering source approval due to the flight-critical nature of the item, necessitating that only approved sources may submit proposals, as the technical data and manufacturing knowledge are not readily available to the Government. Interested parties must ensure compliance with the Source Approval Information Brochures and submit all required documentation with their proposals, as offers lacking necessary data will not be considered. For inquiries, Tara R. Hartung can be contacted at (215) 697-4295 or via email at TARA.R.HARTUNG.CIV@US.NAVY.MIL, with a proposal submission deadline of 45 days from the notice publication date.
