[MarkShot]

Well, I copied my career so that I could replay the attack a number of times to see what I could learn from it:

(1) Escorts were not really in the convoy themselves. The fire which was being directed at my attack scope was coming from the merchants themselves. Although this fire is to be taken seriously, there is certainly adequate time to get off a spread of four provided that you properly anticipate a bore sited AOB 90 attack on a close merchant.

(2) Given the above, it is possible to have your solution at 80% readiness before raising the scope. Thus, as the scope comes up, you can do the final refinement and launch.

(3) Once the fish are away, it's time to crash dive anyway. Watching kills is always the mark of inexperience in subsims ... like any good sniper, one shoots and displaces immediately.

(4) So, it is my estimation that such attacks are completely viable.

My biggest fear in making such attacks be it: AOD, SH1, or SH3 is that you come to PD in the direct path of a merchant which runs over your boat. With contacts on here, this is not too bad, since you can really see their path. Even in AOD, it can be worked out. If you have fast swinging lines of bearing with one group and a single line holding steady, then you are on a collision course. Without contacts on in SH3, you could get the same thing by having sonar tracking the closest merchant; once again a rapidly closing close merchant with no bearing change is an impending collision.
