The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support Mechanicsburg, is seeking to procure four circuit card assemblies for repair and modification purposes. The procurement is limited to approved sources only, as the government does not own the data or rights necessary to purchase or contract repair from additional sources, making it uneconomical to reverse engineer the part. This acquisition is critical for maintaining operational capabilities, and interested parties must comply with specific inspection system requirements and submit their proposals within 45 days of the notice. For further inquiries, interested vendors can contact Helen I. Carmelo at (215) 697-0000 or via email at HELEN.I.CARMELO.CIV@US.NAVY.MIL.
