NATTC was at NAS Jacksonville? We now have what is known as CNATTU, and that is over by hangar 1000 (the pentagon shapped hanger that houses the VR squadrons on one side, and P-3's on the other). The only thing near there is the Target Shopping center that is down from the commercial gate entrance past the Yorktown Gate. Not sure what you mean by the A&R hangar either.. FRC SE (formerly known as NADEP Jax) has a huge set of hangar fascilities that look to date back to the 40's & 50's to me right in the center of the base. Not sure when the last time you saw it was, but they tore down the old amphibious aircraft hangar's and built a brand new hangar for the HSL/HSM squadrons. Now they are in the process of tearing down, and building new hangar's for the P-3/P-8 squadrons.
