I know this is really just self-congratulatory, but as a pretty new Captain, this was big for me!
In my full real setting TMO2.1 RSRD campaign, on Oct 25th, 1944 in the USS Balao, I ran into Admiral Kurita's Center Fleet coming through the San Bernardino Strait. Luckily, I caught them on radar soon enough to get a modified 45 degree angle O'kane shot on the passing fleet that was steaming along at 28 knots.
I guess the flanking destroyers were going too fast for their sonars to be working efficiently, because they steamed right past, with one cruising right over my head! I held my breath as I watched destroyers, heavy cruisers and battleships cruise by. It was hard to check my fire with these juicy targets lined up, but MY target was at the back of the column.
Finally, bringing up the rear, the HUUUUGE form of the Yamato (or Musashi) slid closer to my crosshairs.
Unleashing a salvo of six MK 14 fish at this behemoth with the O'Kane approach allowing me to space them evenly from bow to stern, I immediately crash dived to nearly 600 feet, dodging ash cans from at least 4-5 destroyers for a harrowing period of time.
When my sonar showed the sound contacts moving away quickly again, I tentatively rose to periscope depth, where what did I find directly in front of me, but a stationary, badly listing, burning, but still active Yamato-class battleship.
Amazingly, the center fleet went on without it. Apparently they had a rendezvous with Taffy-3 to the south to make
It was so very satisfying to line up a can't miss shot and fire two more torpedoes into the enemy's flagship.
Even with 8 torps in her, it took a terribly long time for the beast to finally capsize. But when she did, she slipped below the waves almost serenely.
With no ability to catch the fleeing center fleet, I moved north along the coast in search of remnants of Ozawa's northern force, which I was unable to locate.
Certainly the benefit of hindsight allowed me some seriously unrealistic advantages, but it sure was fun to take out this monster and evade the entire fleet.
This is my best kill to date and I wish I had frapsed it! I will have to go back to a saved game before the attack and relive it over and over.
What is your best/most fun kill/patrol?
