About this opportunity
The Department of the Navy Naval Sea Systems Command published this sole source justification notice for the procurement of MK88 MOD4 Gun Mount systems and associated hardware as part of an upgrade to the MK38 MOD3 Machine Gun System to meet Counter Unmanned Aerial Systems (C-UAS) requirements for U.S. Navy and U.S. Coast Guard vessels. The contract was awarded to MSI-Defense Systems US LLC on September 30, 2025, with a value of $40 million in FY25 funding. The sole source justification is based on MSI-DS being the original designer, developer, and sole manufacturer of the MK88 MOD4 Gun Mount, possessing unique technical knowledge and integration capabilities that no other company can provide according to the Navy's Program Executive Office determination. The contract includes procurement of multiple MK88 MOD4 Gun Mounts, Maintenance Assist Modules, and On-Board Replacement Parts, with the Navy estimating that duplicative development costs would represent 47% of the contract value if another vendor were selected. The justification was supported by sources sought notices published in October 2024 and February 2025 that received no alternative responses from other potential suppliers.
