The Defense Logistics Agency is seeking qualified sources for the manufacture of a CYLINDER AND PISTON (NSN: 1620-01-625-2795) in support of the BLACKHAWK weapon system, with performance expected at Redstone Arsenal, Alabama. This acquisition is currently limited to approved sources due to unique design and manufacturing knowledge that is not economically available to the government. The government is interested in all business types, including 8(a), small business, and service-disabled veteran-owned concerns, and encourages firms to seek source approval to compete for future opportunities. No solicitation is available at this time, and no budget amounts or submission timelines are specified in this sources sought notice. Interested contractors must meet prequalification requirements and comply with export control restrictions, including active JCP certification for access to technical data.
