People don't realize that there was more than the UDT training facility out there. North and SouthHutchinson Islands were a huge base during WWII. Today you wouldn't even know the base existed
The Fort Pierce Naval Amphibious Training Base was a 19,280-acre site that extended approximately 25 miles from near Vero Beach to near Jensen Beach and included North and South Hutchinson Islands.The military acquired the site during World War II for the Navy to create a training facility. The Navy constructed more than 450 buildings and other improvements, such as roads and water and sewer systems. By January 1943, detachments of Scouts and Raiders began arriving.
The base fulfilled two primary missions during World War II. Its original mission was amphibious training, including training for Naval Underwater Demolition Teams. Amphibious training missions included use of high explosive rockets, bombs, antiaircraft guns and small arms.
