Marine Corps Support Facility Blount Island
Nestled along the scenic St. Johns River with direct access to the Atlantic Ocean, Marine Corps Support Facility Blount Island powers cutting edge logistics and tip of the spear operations. The installations department sustains this mission through facility maintenance, construction, safety, supply and environmental stewardship—all critical to Blount Island Command’s prepositioning programs.
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.
