The Department of Defense, through the Department of the Navy's NAVSUP Weapon Systems Support, is seeking proposals for the procurement of six units of the MISSION RELAY ASSEM, identified by NSN 7R-1680-015752561-BL and REF NR 96550-01031-042. This procurement is critical as the item is flight critical and requires Government source approval prior to contract award, with only previously approved sources being solicited due to the lack of adequate technical data for competitive solicitation. Interested vendors must submit the necessary documentation as outlined in the NAVSUP WSS Source Approval Information Brochure, and proposals must be directed to Dana L. Scott at dana.scott@navy.mil, with the understanding that offers lacking required data will not be considered. The timeline for source approval may affect the award process, emphasizing the urgency of meeting Government requirements.
