The Department of Defense, through the Department of the Navy's NAVSUP Weapon Systems Support, is seeking proposals for the procurement of 32 units of the Circuit Card Assembly, identified by NSN 0R-5998-016930430-P8 and reference number 1194933-1. Due to the flight-critical nature of this item and the lack of adequate technical data for competitive solicitation, only previously approved sources will be considered for this contract, which requires Government source approval prior to award. Interested parties must submit the necessary documentation as outlined in the NAVSUP Source Approval Information Brochures, and proposals must be submitted within 45 days of this notice, with the understanding that the Government may proceed with award based on Fleet support needs if source approval cannot be processed in time. For further inquiries, Patrick Horan can be contacted at (215) 697-0275 or via email at PATRICK.J.HORAN1@NAVY.MIL.
