The mission of NAS Jacksonville is to " Enable Warfighter Readiness." Focused directly on support of operational units aboard the base and throughout the fleet, station personnel work around the clock providing services to the carrier strike groups.
NAS Jacksonville, a master air and industrial base, consists of more than 110 tenant commands. The installation is home to the new P-8A Poseidon which will replace the P-3C Orion, a long-range anti-submarine reconnaissance and maritime patrol aircraft. Base squadrons also fly the C-130 Hercules and C-40 Clipper. The helicoptor squadrons currently operate the new MH-60 Romeo helicopters which are replacing the SH-60F Seahawk anti-submarine warfare helicopters.
NAS Jacksonville is home to Patrol Squadron Thirty (VP-30), the Navy's largest aviation squadron and the only Poseidon/Orion Fleet Replacement Squadron. VP-30 prepares and trains U.S. and foreign pilots, air crew and maintenance personnel.
