Super Sub in Gilbert and Marshall Islands Scenario

[lemaster_k6466]

WTF is the idea behind the indestructible sub in this scenario? It is absurd. I attacked it over 10 times with depth charges and torpedoes, and it just goes merrily along sinking my capital ships. Is this supposed to be a funny?

It takes some doing to kill it, but it can be done. I usually send up at least one additional Destroyer up to the island to help the one escorting the landing party. Sending up two is very helpful. Not only do they help kill "Indestructo" they can bombard the middle island and you will need them for the second part of the mission.

Yeah, it is a royal pain but it can be done. Improved sonar and depth charges help as well.

I agree, that sub ruins the scenario. I believe Deep Dive ability is the main problem. Its untochable even by my destroyers. And is also wrong to face a 5 star unit so early. Should be revised.

Is there any other valid tactic here besides just shipping destroyers in your navy?

Bring at least 4 destroyers and deploy 2 of them as close to that nasty sub as possible. Make sure that all of your destroyers have the improved sonar and depth charge projectors. Don't forget that torpedo bombers can attack subs too and don't forget about the fighter escort if you do that. Even better, your own subs can attack enemy subs too because of the torpedoes. Please keep in mind that the enemy sub must be made visible by sonar or with the radar program HQ skill before your torpedo bomber/subs can attack it. Having unlocked the training program HQ skill is also really helpful. That gives all auxiliary units two level ups and you can give them two abilities right at the start of a scenario.

Since you need to have a level 3 unit before you can unlock the full potential of the training program HQ skill it is highly advisable to pick a unit and make sure it gets to level 3 before that scenario. I reached level 3 with a sub and a fighter during guadalcanal. I gave that sub the sub hero and used it to land the final blow on the japanese sub. With the abilities wreck ships, need more ammo and one more shot the japanese sub didn't stand a chance. And my own destroyers, as well as the auxiliary destroyer, had dealt damage to that sub too. The destroyers probably would have killed the sub on their own but that way i could avoid taking even more damage from that sub and it freed my destroyers up to do other, more important things, like shore bombardments.

Yes, that japanese sub is a very nasty surprise if you encounter it in your first playthrough, especially if you don't fully understand the game mechanics at the time. I had a really hard time when i played this game for the first time when i found this sub. However, the much harder thing in this scenario is capturing the 3 islands in only 4 turns. One mistake and you have to restart the scenario.

This is ruining the game for me. I guess I will go back and make super destroyers and try again. but it is really poor game design IMO. No wonder I can't find any videos that go past this point on YouTube for the U.S. campaign.

For me the sub is a bit of a pain. But...you need DDs for the Marshall part of the scenario, if you have not gotten that far as of yet. You have to deal with more regular IJN subs while escorting your transports. So, I just make sure I have DDs to take out Hero IJN then move on. It really is not that difficult to sink the first one.

that sub has a hero. That is why it is so good. I sent my torpedo bombers after it

I hit it with 5 destroyers and didn't have any issues with it.
