NavyRecognition reports that high flying, fast, long endurance Triton MQ-4C Navy intelligence, surveillance, and reconnaissance data collection drones are being based at Mayport, FL.
Detachments will rotate to distant theaters, but they will of course fly missions out of Mayport if only to maintain proficiency. Hopefully we will see these used to support Coast Guard interdiction missions.

To fill in some info not readily known. The Ops Center for the flights beyond USEC will be at NAS JAX. Mayport will be the FOB where a/c are actually hangared and flown from. Since NAVFORSOUTH is at Mayport I am sure its rqmts will get into the mix. But I have a distinct impression that tasking will come from a higher level

Status report. To me, it seems to be progressing very slowly.
