Thanks for the fast reply Molon Labe. I've uploaded the file to CADC, here's the link:

It was played with LWAMI 3.09 and nothing else. The original mission was one I designed to help myself learn long range TMA and one-on-one ASW combat. It's extremely basic, with no units other than my 688i and a randomly chosen and placed enemy sub (Akula-I Imp., Agosta, Ming, Han, Delta IV or Typhoon).
The save-game is right at the point where I'm about to fire. Solution is rock solid, but I only have a TA contact. Sub is still unclassifiable, but the TPK that works best with my solution is 10, so I am assuming it's a D/E boat. It is a little more than 18 kyds away and hasn't heard me yet. Tubes 1 and 2 are targeted and presets set to RTE 16000, depth for 1 is 200, depth for 2 is 600, speed 55, floor 3000, active and snake. Tubes 1 and 2 are flooded/equalized, but the muzzle doors aren't open yet.
If you could give it a quick try that would be great. I have played this save-game a couple times now and I have only managed to kill the sub twice, and neither time was very elegant. Any advice would be very much appreciated.
