The AF Tankers make it easier to do business, certainly, but Naval Air would still be able to operate at range without AF tanking and with internal tanking only. I'm sure it would hurt, but it could still be done. And don't forget, the Marine KC130s can go anywhere the AF tankers can and more, and provide give to get strike packages/ CAS players downrange in addition to the organic tankers. Is it perfect, no, but it works.The AF would rather take the Navy's carrier money and waste it on frivolous crap that does little to support the Ground Combat Element...and as always is pretty ruthless in making that happen. Maybe the Army can take them back (Army Air Force again, anyone?)
