I played this scenario again last night with a SCX2/SCU install. Tough cookie! It kept being fired upon without a moments notice or even a faint frequency line in narrowband. On one occasion within a few minutes of game start. No way that akula (or whatever the exact type it is) would have me ranged up in that time. Even if it spawned in my vicinity. Clearly the AI cheats with TMA.
Anyway, I edited the starting speed of the playable 688i sub to 1 knot. I didn't want my 5 kts speed to give me away before I could slow it down. That significantly increased my lifetime duration. Also going deeper (1500 ft, just above crushdepth) helped. But at 1 or 2 knots that takes ages. Afterwards you can increase speed to 8-10kts after that to close-up or search. I got pretty close, upto 3nm trying to get positive passive id, but then he detected me and was again shark-meat. Nasty flying torpedos got me. 5 of 'em.
