About the company
Msi-Defence Systems US, LLC, a foreign-owned manufacturer of electro-optic sights, gun mounts, and precision naval defense systems, operates exclusively as a prime contractor to the Department of the Navy Naval Sea Systems Command, holding a 100% customer concentration across $143.5 million in combined potential value across twenty awards issued since 2022. The company, headquartered in Rock Hill, South Carolina, competes entirely on a non-set-aside, sole-source basis, reflecting its proprietary manufacturing capabilities and exclusive supplier status for specialized naval surface combatant weapons systems.
Msi-Defence Systems' capability portfolio centers on the design, development, production, and sustainment of advanced naval defense systems integral to surface combatant modernization and maintenance. Representative prime work includes a $34.6 million definitive firm-fixed-price contract for design and production of MK88 MOD4 Gun Mount systems (awarded September 30, 2025, completion December 30, 2026); a $6.6 million cost-plus-fixed-fee delivery order for FY26–FY27 engineering services under firm fixed price (awarded July 9, 2026, completion July 1, 2027); and a $23.5 million definitive contract for MK 88 MOD 4 Gun Mount procurement (awarded September 28, 2023, completion May 9, 2025). The company holds two active single-award indefinite delivery contracts and one single-award basic ordering agreement with Naval Sea Systems Command. The primary IDC, valued at $29.3 million with a ceiling through September 28, 2026, covers MK 48 MOD 2 Electro-Optical Sight spare parts, repair efforts, and interface design documentation supporting the MK 38 MOD 4 Gun Weapon System; five delivery orders totaling $25.7 million have been issued under this vehicle. The basic ordering agreement, established August 24, 2023, with no specified ceiling and extending through June 30, 2028, covers MK38 MOD4 Machine Gun System components and services; four delivery orders totaling $29.7 million have been placed against it, including a $19.5 million cost-plus-fixed-fee order for Operation Inherent Resolve requirements (awarded December 13, 2024, completion December 22, 2027).
Activity has grown from three awards in 2022 to seven in 2025, with two awards issued in 2026 so far. Six awards carrying combined potential value of $72.3 million reach ultimate completion within the next twenty-four months, creating significant recompete exposure. The company performs all work at its Rock Hill facility. In its sole subcontractor role, Msi-Defence Systems delivered Iraq vendor maintenance and repair services to Amentum Services, Inc. (advanced payment, August 21, 2025). Work spans the Small Arms, Ordnance, and Ordnance Accessories Manufacturing NAICS (eight awards) and Search, Detection, Navigation, Guidance, Aeronautical, and Nautical System and Instrument Manufacturing NAICS (seven awards), with night vision and electro-optic equipment representing the dominant PSC category across the portfolio.
