So far I needed 13 sorties to clear hard mode TP bar. From those 13 runs, I made it 5 times to the boss with 2 S ranks and 3 A ranks. I also killed the boss 4 times. From 8 retreats 5 were on node B and only 3 were blamed to submarine nodes, 1 at A and 2 at node D.

Long story short, submarines are not a problem as long as you sparkle your fleets. Even I didn't make use of ASW gear.
