I had a lucky day, I got appointed to an patrol in the Truk area. I went if something was up at the Truk harbour, last time I went there there was a stationary light cruiser. When I did my observation periscope up I saw a big tasty Fuso battleship, and then I heard "ship spotted", I looked at the bearings and there it was. A stationary Yamato, it took al my stern and aft torpedo's, 8 in total before it sunk.

Lucky me there weren't any destroyers around, I went of silent running and to battlestations and the torps were reloaded in no time. Sunk the Fuso too with 6 torps.

That was a productive patrol.. :D

True, you would guess that such ships would be guarded closely, the DD's at truk were all guarding further away from the harbour. Though, in my case, there were a lot of planes buzzing around, didn't do much in the dead of the night.

So far, just fooling with the quick missions (all I have time for) I have made at least a dozen attacks on Yamato class battleships. I've put as many as ten torpedoes into them, and not sunk one yet.

I have even resorted to aiming my torpedoes to stop the ship, one way or the other, so I can hang around and put more fish in it. I actually hit one with six torpedoes, all between the forward turret and the bow, and it only slowed it down to 10 knots from 16 knots. The destroyers kept me so busy I couldn't get a shot. The next time, I put 4 torpedoes directly into her screws, all 4 hits were from the shafts to the screws, and lifted the stern up. She steamed off at 12 knots, and the destroyers swarmed all over me.

The best one was 6 hits from the bow tubes, all in the center of the starboard side from less than 1000 yards, followed by popping up on the port side and putting 4 from the stern tubes into the port side dead center from about 700 yards. I think she steamed off at 10-12 knots.:damn:

Try spreading your shots out. If I get a broadside shot i'll put one at the stern, one under the after battery, one under the stack, one under the tallest point in the superstructure, and one each under the two forward batteries. This normally slow it down pretty good.

If I'm lucky I'll get some secondaries and after 5 minutes or so it'll develop a good list. I'll swing around and pop four more fish into it and that is normally enough to make it pop.

I remember making single mission a long long time ago, and if I remember rightly I think I used about 16-18 fish into her starboard side...from stem to stern.

That finally finished her off, after waiting some time for her to capsize

I sank one a while back with 5 fish. First wone caused a massive explosion forward, and it went down after the next 5 hits, still moving at about 9 kts. Of course then the 5 escorting DD's had a few things to say to me about it...

But the third Yamato (Shinano) went down with just 4 submarine torpedo hits.

The Shinano's demise had a lot to do with stupidity and circumstance. Not all of her watertight doors had been installed. The ship's compartments hadn't been tested for water tightness and most of her crew was untrained with a good percentage of them being civilian dockyard workers still helping fit the vessel out. Plus, Capt Abe insisting on proceeding at speed despite the torpedo hits judging the damage inconsequential. Rather than face the embarrassment he went down with the ship. Fearing the impact on national morale, the sinking was concealed from the Japanese people until after the war.

All true,and the fact that she was completed as a CV,not a BB. Different subdivision,avgas storages tanks probably empty.

There was also a weak spot in the Yamato class armor where the torpedo blister met the rest of the hull. The Archerfish's torpedoes all hit this spot.
