The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is seeking proposals for the procurement of 23 units of the signal converter (NSN 7R-5895-014608011-XH, REF NR PS491-1). 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 vendors must provide comprehensive documentation as outlined in the NAVSUP Source Approval Information Brochures, and failure to do so will result in disqualification from the award process. For further inquiries, Danielle Diciacco can be contacted at (215) 697-5970 or via email at DANIELLE.DICIACCO.CIV@US.NAVY.MIL.
