The Defense Logistics Agency is conducting market research to identify potential manufacturing sources for multiple items supporting the Patriot Weapons System, with performance at Redstone Arsenal, Alabama. This is not a solicitation, and no funds are available to pay for response preparation. The government is interested in all business types, including small and disadvantaged businesses, but only a limited number of responsible sources currently qualify. Firms must obtain engineering source approval from the U.S. Army’s System Readiness Directorate to be eligible for future awards. No budget amounts or submission timelines are specified in this announcement.
