Should have thought of that before ditching the Lockheed Electra in favor of the 737 as its land based ASW component. The 737 may get there more quickly and comfortably, and help make its pilots more marketable for the airlines, but it lacks the long, slow loiter.
Maybe they need to roll out some blimps again, as well.
Actually the radius of the P-8 and the P-3 aren't all that different.
