As well as the duds I had something else disturbing happen this morning, it is early Januray 1942, I am in USS Sailfish patrolling the choke point in the Malaka Straits just near Borneo, dawn passes quietly then the watch spots a large Jap convoy making its way through the slot, I radio it in (I'm using TM 1.7.5, RSRDC and ROW) and get a message back saying good catch, go sink 'em, so I submerge and develop my attack run, sea is running high, winds at 15kts+ so I figure it is going to be difficult for the minesweepers guarding the convoy to spot my periscope so I get as close as possible and fire a spread of 4 torps, I immediately lower the scope and set dive for 200 feet and order a turn of 180 degrees in case I can get an aft shot in later, I hear the torps launch followed by a massive explosion litterally a second after the torp left the tube, the crew start reporting damage straight away in the bow.... meanwhile 2 of the three remaining torps detonate early in the rough seas and the lucky last goes on to hit home and break the back of a small Maru (poor consolation prize as it was...), I put my best mechanical men into damage control to stem the flood in the bow torpedo tubes, they work feverishly until we hit 200 feet, but she wont stop, slowly dropping deeper foot by foot, meanwhile 3 Jap minesweepers are dropping cans like hail overhead, some uncomfortably close but none cause me any damage, I go to the external view to look at the damage from the outside and almost the entire bow is smashed off, as I am doing this there is a massive explosion from the bow and down she goes, not from a depth charge hit but from an internal explosion.... i am beside myself, I have never seen this before, a torp explodes prematurely in the tube (or just outside the tube I would say) then a few minutes later another one, or the ammo bunker goes up as we sink past 250+ feet!! God I love this game.....
