The Defense Logistics Agency is conducting market research to identify potential sources for the manufacture of a Circuit Card Assembly (NSN 5998-01-497-3340, Part #13508140) used in the Patriot Missile Weapon System. Performance of services would be at Redstone Arsenal, Alabama. The government does not own the rights to the technical data needed for this part, so it is currently procured from a limited number of responsible sources under FAR 6.302-1(a)(2). Interested firms must seek source approval and meet prequalification requirements to be eligible for future awards. No budget or submission timelines are specified in this sources sought synopsis.
