Howard Hughes Vindicated!

DARPA, the Defense Department's official mad-scientist branch, has signed contracts with two companies to develop a super-heavy-lift flying boat for military transport. Here's the article from the US Naval Institute Web site.

Why resurrect a technology which has been sidelined for seventy years? Since the end of World War II flying boats have hung on in a couple of very specialized niches but otherwise they've joined long-range passenger airships in the category of "stuff we don't use any more." The modern world has paved runways everywhere, so airplanes don't need to land on the ocean.

Unless . . . you're the US Navy and Marine Corps, and you're thinking very hard about how you'd fight against a certain large country on the western side of the Pacific. You'd want to use the island chain running from Kamchatka to Australia as a line of unsinkable air bases and combat platforms. You'd want to be able to move forces rapidly around that region, which means you need something faster (and cheaper to replace) than amphibious landing ships. 

Speculation: I expect older ballistic missile submarines will not be scrapped as newer boats replace them. Instead they're going to be repurposed as undersea transports, suitable for rapid, secret deployment of small combat units to islands near Asia.
