Just bagged a Sierra II blockading the Etorofu Strait, in the Kuril Island Chain. I was in a Flt I 688.
It was hard to stay stealthy and also keep up with his 5kt speed. Detected him on the TA at 20,000 yds. He was heading straight for the east coast of Iturup Island.
Even though I was at 24,000 yds, dead astern, he had land blocking his way ahead - I had to take the shot (3xMk 48s, 30 second spread)
2 hits and the 3rd went right past the destroyed sub. I was never detected.
I good bit of "payback", because a Sierra thumped me west of the Hebrides a few weeks ago!
