There are three bases in the what is considered the "TRI-BASE"
area. The oldest of three Navy installations in the area, NAS
Jacksonville occupies approximately 3,400 acres along the scenic St. Johns River
and employs more than 17,000 active duty and civilian
personnel. Naval Air Station Jacksonville is a multi-mission base
hosting more than 100 tenant commands. Located along the west bank of the St.
John's River in Northeast Florida.
The other installation close to NS
Mayport within the TRI-BASE area is Submarine Base Kingsbay. The base
is home to Submarine Group 10, Submarine Squadrons 16 & 20, Trident Training
Facility, Trident Refit Facility, Strategic Weapons Facility Atlantic, and other
support-providing commands. In addition to being an integral part of our
nation's strategic deterrence program, Kings Bay has attained and sustained
award-winning results unsurpassed in Navy Region Southeast or other submarine
and shore commands in the U.S. Navy.
