Maybe with the NTTR map coming soon we can say that we already have a hometown base, I know it is not a NAS, but it is a really good base to do certification/training for every type of aircraft.
Then we can train tactics, DACT, procedures, etc in Red Flag type exercises on that base. And this is valid for jets, choppers and land units(CA).
With that, maybe we don´t need a very big map, just two or three, we have the Georgia one already and is a good example, deployment maps with a typical combat radius size and a big part of sea for the Hornet and a friendly land base for the rest.
In this way we can simulate all the phases of a pilot´s combat life quiet well and save some work and time, maybe, with the development of bigger maps.
Ex Yugoslavia and the Persian Gulf will be perfect for me with this idea on mind. No Fly Zones with some air to air combat and lots of ground attacks/SEAD missions and MEDEVAC/CAS for the choppers.
Obviously this is a valid approach for the modern western aviation.
The only thing I will miss is the ferry flight from Nellis to the carrier with the Hornet.
