What’s left of Yellow Water Naval Air Gunnery School.

Built in 1942 to train sailors in gunnery, Jax NAGS was one of 3 facilities in the United States where this training took place over the course of WWII. With the school closing in 1946, the school was attached to / renamed to NAS Cecil Field during the Cold War. With the facility being secretly used to house nuclear weapons.

Originally having 80+ bunkers, three rows of fences, watch towers, sensors, and cameras. The facility was formally decommissioned in 1999, and split into multiple different parcels. with much of it becoming tall pine forest. Very little remains of the facility today. The facility was listed as an EPA superfund site until 2019, where all 17,000 acres were transferred to the City of Jacksonville. The EPA claims that since the transfer of ownership in 2019, more than $330 million has been invested in the infrastructure in the area. The effects are visible. With big-name warehouses on the land & new clearings being established today. The old yellow Water NAGS / NAS Cecil Field appears to have development on its horizon.
