• 2 Sunken Japanese Subs Are Found Off Hawaii (One of them is the I-201, the other is the I-14 which is just as impressive as the I-401.)

The Sen Taka (submarine, high speed) was capable of running faster submerged than surfaced for up to an hour (in high bursts of speed). The only WWII submarine comparable in underwater speed to the I-201 class was the German Type XXI "Elektroboote" class.

The I-201 class had streamlined all-welded hulls (with retractable 25mm gun mounts to maintain the streamlining), high capacity cell batteries and electric motors capable of providing 5,000 hp, not to mention snorkels to allow cruising while submerged and recharging the batteries while underwater.

Only three were built (I-201, I-202 and I-203) before the end of the war and none of them ever saw operational use.

So somebody doesn't wanna cruise, huh.

I-201...Nioi? Smell? :)
