BreakingDefense has a post on the inadequacies of Guam’s infrastructure for support of additional Military presence. I’m referencing it here because, I think in the long run we are going to need to put more assets in Guam, to look after the huge Western Pacific EEZ. Ultimately I think it would be a good idea to base two or three Offshore Patrol Cutters there. Right now the Coast Guard has a 225 foot buoy tender and two 110s. The Navy supplies SAR helicopter assets in lieu of CG air assets.
To see how much of our EEZ is in the Western Pacific, look here, and keep in mind that Mercator projections are deceptive, making areas in the high lattitudes looks disproportionately large. The US has the Largest EEZ in the World and 85% of it is in PACAREA.
Late addition: Incidentally, it is about 3300 nautical miles from Guam to Hawaii, long way. The HC-130Js can fly that far unrefueled, if we had any in the Pacific, but the older “H” models at CGAS Barbers Point can’t. Even the “J”s would not have a lot of excess for doing searches flying between Oahu and Andersen AFB. It is almost 600 miles further from Kodiak. Maybe we ought to have some fixed wing there too.
