While attacking a convoy at night last mission, I had a fat T3 tanker lined up nicely and fired a 3 torp salvo. All 3 torps detonated prematurely just after being fired (or at least I think that's what happened, all I heard was one loud boom and when I pressed F6 I found no torpedoes visible). I think my torpedoes were on magnetic so premature det is the likely cause, then again I thought at the time the 3 torpedoes may have collided with each other. How likely is this latter possiblity? Has anyone had torpedoes collide? This would make salvoes risky...
