The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is seeking proposals for the procurement of 39 units of the WING ASSEMBLY, AIRCRAFT, and similar replacement parts. This procurement requires government source approval prior to contract award due to the flight-critical nature of the item, and only previously approved sources will be solicited. The selected supplier must provide detailed technical data and evidence of experience in producing similar items, as the approval process for new sources is lengthy and may not align with government timelines. Interested parties should contact Tara R. Hartung at (215) 697-4295 or via email at TARA.R.HARTUNG.CIV@US.NAVY.MIL for further information, and proposals must be submitted within 45 days of the notice publication.
