Sub also moving at round 10 knots, or alternatively the maximum speed which did not interfere with the TA.

Conclusions

The starboard TA of the stock playable subs are effectively identical - they all detected the ship at about 60nm out. Whichever platform you select, the TA result is the same. Smiliarly, I tried the Trafalgar class and the late Typhoon, and their TAs detected the target at the same range.

I also tried the SCU 1975 Sturgeon, and its TA was not as effective - it was about 50nm out when the target showed up.

I then tried using the SCEdit to tweak the TA capabilities to improve them. I tried several different parameters, as the SCEdit does not fully explain what the numbers associated with the TA are.

Absolutely no difference. Conclusion - the TA capabilities of player platforms cannot be adjusted - at least not by me.
