Marine Corps Support Facility Blount Island
The installation department provides the infrastructure, engineering, environmental stewardship and installation support required to sustain Blount Island Command's global positioning mission. Through facilities management, infrastructure modernization and mission assurance activities, the department maintains resilient installation capabilities supporting integrated global sustainment operations.
Spanning more than 1,200 acres and about 110 buildings, MCSF-BI is a hub of activity with port operations, specialized repair facilities and conservation areas. A private 1,000-foot marine slipway—with five berths and a high-capacity rail-mounted crane—enables efficient loading and offloading of U.S. Navy maritime prepositioning ships, ensuring global readiness.
According to the 2023 economic impact analysis by Marine Corps Installations East, more than $188 million flows through MCSF-BI each year in salaries, construction, supplies, and services. Purchasing and contracting alone deliver nearly $100 million into the regional economy.
