The Department of Defense, through the NAVSUP Weapon Systems Support office, is seeking qualified contractors to support the repair and modification of specific Navy Weapon System items under the existing BOA N00383-21-G-Y101. The procurement involves adding four National Item Identification Numbers (NIINs) to the current agreement, specifically NIINs 016218637, 015102945, 015123483, and 014624709, which are critical for the maintenance of support equipment. The government intends to award this modification to BAE Systems Controls Inc., as they are the only approved source capable of fulfilling the requirements, given that the government does not possess the necessary data for repairs or manufacturing. Interested parties must submit their capability statements within five days of the notice publication to be considered, and any new sources must provide the required information as outlined in the NAVSUP-WSS Source Approval Information Brochure for Repair.
