Yep, increasing the time to impact is important.

Next, increasing your initial distance from the escorts is important, since that also buys time.

Finally, I know in SH3/SH4, the AI has hearing that rivals modern towed arrays, but in AOD immediately after shooting that is when a well timed deep dive and sprint can save you. You have maybe a 4-8 minutes that you can run at high speed before they get close enough to track you. So, you want to put distance between where you shot from (since that is where they will look) and where you are when they reach that location.

Also, you should have your escape route selected. Usually, heading under the convoy and exiting out the back is a decent idea. The escorts if they don't have too good idea of where you shot from will assemble for the search on the side of the convoy upon which the fish struck.

When they get close after you have slowed to 1kts, you go as deep as you can for as long as your compressed air can keep you from flooding (about one hour). That will make it harder for them.

If you did it right, rather than getting a few HSS LOBs surrounding you, they will be mainly off to one side and they where appear to oscillate back on forth. That means that they have picked another location and are circling it and not you! You should get to hear depth charges in the distance.

Then, you just crawl quietly away.
