The Department of Homeland Security, specifically the United States Coast Guard (USCG), intends to award a sole-source contract to Appleton Marine, Inc. for the procurement of a critical spare shipset of aft folding boom cranes for the National Security Cutter (NSC) fleet. This procurement is essential to enhance maintenance efficiency and reduce downtime, thereby increasing the mission availability of the cutters, as the cranes are uniquely designed to integrate with the NSC's existing systems. The decision to proceed with a sole-source contract is supported by market research confirming that only Appleton Marine can fulfill these specialized requirements, and the procurement is justified under relevant federal regulations.
