There are many reasons why Guam is the perfect Pacific stronghold. Mostly due to "the goldilocks factor". It's small enough to defend , large enough to hold a tremendous number of troops. Apra harbor is a great deal larger than the Gorn realizes. Not only COULD it hold the bulk of the US fleet, after August 1944 , it DID! There were 4 massive airfields built, and several smaller. There could have been more. And the strangest reason is a secret hidden within it's name. According to Chamorro's (the native people of the Marianas) Guam's name was derived from Guuham. Litterly "We have water". It may sound like a chamber of commerce slogan , but Guam has lots and lots of water. Most Pacific island have enough for the locals , but not much more. Guam could easily export it. Not a bad thing to have when you have over a million troops on the island. (Which they could...apologies to the ill informed congressman who thought 5,000 Marines would make the island flip over. For many years the island held a quarter of a million PERMANETLTY assigned troops.)
The point is ANY base can be taken , if everything around it is taken. EVENTUALLY. Pearl Harbor could have been in that fix. But instead of seeing Guam as a "Ft. Apache", surrounded and cut off, planners of the day saw it as a forward deployed beach head capable of menacing Japan with aircraft , surface ships and most of all submarines. As it did shortly after "Liberation day" in July 1944, when SUBPAC, PACKFLT and Nimitz moved their head quarters there. And Guam became the biggest supply base in the Pacific (a position it held till after the Vietnam war).
Excellent analysis. I suppose you once being based there has something to do with that? [:D]
Your point on a fresh water supply really hits the nail on the head. There are other bases that might give Guam reasonable competition as far as anchorage/land mass/etc. go, but this quote from Beans, Bullets, and Black Oil illustrates the point very well:
(emphasis mine)"Water became a major problem in the middle of the largest of all oceans. There was little or no fresh water on many atolls while the demands for it on islands with some supply were too great for the local sources. Another major factor in water requirement was the fact that hundreds of small vessels were not equipped with their own distilling apparatus or found their tank capacity insufficient when at sea for extended periods. To supply water, several new tankers of the oiler and gasoline tanker types were employed for more than a year solely in transporting pure water from supply points at Oa'hu, Guam, and Manus to anchorages where the fleet was temporarily based [...]"
We all know from playing WitPAE how precious the TK and AO types are. That really says something that 1) some of these vessels were employed for more than a year(!) to deliver fresh water and 2) there were only three(!) viable sources in the Central Pacific, one of those being Pearl itself.
I think the shortcomings of Guam were:
1) the relative lack of security and navigability of the harbor:
"Squadron Twelve, nicknamed 'harbor stretcher,' had been commissioned in March 1944 for the primary purpose of increasing depths in channels and harbors where major fleet units would anchor, or where coral reefs and shallow water created serious navigational hazards.By far the largest operation Twelve undertook was at Guam"
I'm guessing the "Glass Breakwater", as well as (I assume) a deepening of the harbor, part of that effort?
2) its defensibility considering how far it was from the US (i.e. the need for fortifications and storage to hold it long enough until naval reinforcements could arrive in quantity from CONUS)
Both of these could be largely solved by throwing money at the problem, and Guam had enough going for it in all the other categories to make a plausible argument why such an expenditure would be warranted. The Depression-era spending cuts and treaties put an end to the development needed to make it truly a viable base before the US entered the war.
