Located along the banks of the St. Johns River, the site and the weather conditions make the base a premier aviation facility. Initially conducting primary and seaplane training, it expanded to training pilots in almost every type of aircraft the Navy has flown. The Navy's elite precision aviators, the Blue Angels, were formed at the base in 1946. Today, as a master anti submarine base, it remains home to 15 aviation squadrons; some 115 tenant commands and almost 20,000 military, civilian, and contract employees work at the station daily.
