Let’s open a new conversation within the naval community. And let’s not accept “because…Rickover!!!” or kindred excuses for staying with current methods and hardware. If not diesel submarines, why not?
In other words,if Beijing wants to deny U.S. forces access to the theater, U.S. and Japanese commanders should reply in kind. They can deploy submarines along the first island chain to fight in concert with surface forces, detachments of missile-armed land troops, and shore-based tactical aircraft.
“Underway on nuclear power“, radioed the skipper of USS Nautilus in 1955, after taking history’s first nuclear-powered attack submarine to sea for the first time. Nautilus‘s maiden cruise left an indelible imprint on the navy. Her success, cheered on by the likes of Admiral Hyman Rickover, the godfather of naval nuclear propulsion, helped encode the supremacy of atomic power in the submarine force’s cultural DNA.
Things were never the same after that. America built its last diesel-electric sub, once the state of the art, not long after Nautilus took to the sea. [Not since 1990](http://en.m.wikipedia.org/wiki/USS_Blueback_(SS-581%29) has the U.S. Navy operated conventionally powered boats. It’s been longer than that since they were frontline fighting ships. For a quarter-century, then, it’s been all nukes, all the time. No U.S. shipbuilder even constructs diesel boats nowadays.
