Also, our new sub hunter, the P-8 Poseidon, lacks a MAD.
i was being much more optimistic... but your notion seems equally worthy of consideration too...
The U.S. Navy never had P-3s in Korea or Japan. At the height of the Cold War all Pacific Fleet P-3s were stationed at Moffitt Field in California and Barber's Point in Hawaii. They deployed to Adak and Midway.
Recently they've deployed P-8s to Okinawa. I have no idea whether that's a permanent plan or not.
