MILLERS ISLAND PROPELLER, INCORPORATED

MILLERS ISLAND PROPELLER, INCORPORATED specializes in the refurbishment, repair, and precision manufacturing of marine propulsion components and shipboard hardware. The company delivers mission-critical solutions for naval and coast guard vessels, with demonstrated expertise in propeller restoration, stuffing box assemblies, and sacrificial anode systems—key elements for corrosion control and mechanical integrity in harsh maritime environments. Their technical capabilities encompass precision machining, metallurgical restoration, and naval propulsion system maintenance, ensuring operational readiness and extended service life for high-value maritime assets. The firm’s focus on durable, mission-essential components reflects a deep understanding of naval engineering standards and the demanding tolerances required for underwater propulsion systems. The contractor has delivered specialized hardware and repair services to both the Department of Defense and the Department of Homeland Security, primarily supporting U.S. Coast Guard and Navy vessel sustainment programs. Their work for these agencies centers on propulsion system maintenance and hull integrity upgrades, indicating a trusted, recurring role in fleet readiness initiatives. The consistent engagement with defense and homeland security entities suggests a reputation for reliability in mission-critical maritime applications. MILLERS ISLAND PROPELLER, INCORPORATED operates primarily within NAICS 336611 (Ship Building and Repairing), with supplementary work in 332510 (Hardware Manufacturing). This positions them as a niche supplier of specialized marine hardware and repair services rather than a full-scale shipbuilder, focusing on subsystems critical to vessel performance and longevity. Their market niche lies in the sustainment of legacy and active-duty maritime platforms requiring precision component restoration. As a small business structured as a 2L entity based in Sparrows Point, Maryland, the company leverages its proximity to major East Coast maritime infrastructure to support federal vessel maintenance programs. While currently holding no formal government certifications, its location and technical focus align it with the U.S. naval industrial base and regional defense supply chains.
