The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is seeking a contractor for the repair and modification of a cooling manifold (NSN 7H-3655-007815552). The procurement involves a single source solicitation for one unit, which is deemed uneconomical to reverse engineer or procure from additional sources due to the lack of ownership of necessary data. This cooling manifold is critical for gas generating and dispensing systems, and the contract is set aside for small businesses under the SBA guidelines. Interested parties must respond within 45 days of the presolicitation notice, and all inquiries should be directed to Helen I. Carmelo at (215) 697-0000 or via email at HELEN.I.CARMELO.CIV@US.NAVY.MIL.
