This is a sources sought notice for market research, not an active solicitation. The Defense Logistics Agency in Redstone Arsenal, Alabama, is seeking to identify potential manufacturers for four specific lift assembly part numbers for the BLACKHAWK weapon system. The acquisition is currently procured under an exception for a single responsible source, but the government is seeking to identify all potential qualified sources, including small businesses. Interested contractors must meet prequalification requirements and be capable of handling all engineering, manufacturing, supply chain, and logistics responsibilities. No solicitation is available at this time, and this notice does not constitute a commitment to issue one.
