Yes as the topic says I sunk a carrier on the surface at the mouth of tokyo bay.
I was sailing about 164 M SE from tokyo harbor and got a contact. It was not a merchent, it was going between 19 and 20 knots, It had to be a warship.

I chased it at flank (21 knots in my gato) and was winning. I finaly cought up with it right at the mouth of tokyo bay, I got into fireing position on the surface, but before my torpedos got halfway, they spotted me.
The torpedos hit 1,2,3,4,5, and 6 no duds, the carrier went up in flames.:p I had no time to admire my kill, only enough time to get away from the fast moveing blips on my radar comeing right at me.

I got away fast to, I put the sub at the hightst speed it could go. The shore units could start there stuff at any second.
I got away. It was a Taiyo Escort Carrier.

17,830 tons plus the two merchents I got earlyer.:p For 26,388 tons.

Going back to midway(base)
