My sub was definitely still well out of range of even the enemies gunboats never mind the larger ship contact behind those so I personally don't think it was the ASROCs unless they can fly a heck of a long way.
I did spot the Bear earlier in the mission but it kept disappearing.
I was using my helicopter around my sub shortly before that to drop some sonar buoys but it had gone by the time of the attack. My ASW plane was being used as an AWACS type thing well back and it never picked up any Bear near the sub at any poin,t but I assume the radar isnt very good on those things - not as good as AWACS anyway.
I had been using my sub at cruise (or faster) to try to get into the action so it could well have been detected but I never saw any enemy sonar buoys at all. The first sign was a torpedo at very close range behind the sub. Then another one from the left side further away I think, and then it seems another from the other side but I cant be sure of that. there must have been at least eight of them as they kept coming. All I know is I seemed to get surrounded by torpedoes bloody fast and they came from nowhere. I rushed my ASW plane over and dropped a load more sonar buoys but didn't find a thing. I turned my subs active sonar on (the towed array was on all the time) to try to detect something but still didnt see anything but I was probably going too fast anyway at that point to get away from the torpedoes. My sub escaped all of them somehow and I never saw what had dropped the torps at all.
I wish I had kept a record of what torps they were, there seemed to be two different types. Either way it was very scary and my sub captain must have been very talented to have got away without a scratch that day.
