Just how were Japanese aircraft launched from the Pacific to get to the East Coast for an attack? According to the National Geographic program, the sub had an unrefueled range of 1 1/2 times around the world, so that it would go from the Pacific to the Atlantic, launch it's seaplanes off the East Coast, and bomb either NYC or DC. Then it would recover the seaplanes and return home. In theory.

That's insane. In 1945? Pure bullshit. I'm disappointed in them.

I agree, how could they have done that without CAFE standards?

Perhaps. But these Japanese subs were captured and tested by the USN after WWII. According to the article, when the Russians demanded to inspect and test the subs themselves, the USN scuttled these huge subs off the coast of Hawaii in 1946.

Presumably the USN could figure out what the unrefueled range was. Remember, that wasn't submurged range.
