This is a Sources Sought Synopsis for market research, not a solicitation, to identify potential manufacturers for multiple items supporting the Patriot Weapons System. The items require engineering source approval from the design control activity, and only a limited number of responsible sources are currently approved. The government is interested in responses from all businesses, including small, 8(a), service-disabled veteran-owned, HUBZone, and women-owned concerns. Firms capable of producing the items must seek source approval to compete for future efforts. No specific budget or performance location is provided, and the place of performance is to be determined.
