The method I used was to take the same four subs you have, and get them all to lvl 50 (iona not needed). Equip each with two torpedos then and send them in.

They should be able to get through to the boss node over half the time (though unlucky streaks definitly will happen), and can kill the boss one in every... maybe ten to twenty runs? The key part is that they can all do cut in attacks, be sure to stick Iona at the bottom of the formation so she always fires last in the night fight, that way everyone else can focus on clearing out as many distractions as possible to increase her odds of actually hitting the boss.

It will take time, lots of repair buckets and a fair amount of supplies, but you should be able to make it through.

(PS: I run 3-3 and 3-4 to level up the submarines quickly, I was able to get all of mine from under 30 to over 50 in about five days)
