How to unlock the Veteran Submarine Commander achievement in Battlestations: Midway - Definitive Guide
At the start, get both submarines moving, and have them both make a beeline for the Enterprise. Raise the periscope of I-26 to spot and track a destroyer to the east of I-25, a Catalina, and several bombers headed out to I-26. Have I-26 crash-dive to crush depth to avoid these threats and head straight to the Enterprise.
There's actually a simpler method - usually the first thing that comes into contact with the I-26 is the Catalina, so just surface and use your pea-shooter to shoot it down. However, for the Catalina patrolling around the I-25 it's a lot more difficult as there are PT-boats in the area, but it's worth taking some damage in return for the downing of this huge annoyance as this will turn the bombers of the Enterprise into headless chickens patrolling with no avail.
The Gilmer will head for whichever sub is discovered first.
Using I-25, set a course for the USS Gilmer and perform the head-on attack to sink this threat quickly. With the Gilmer out of the way, you can try to surface and sink some of the enemy PT boats with your deck gun and machine gun (The PTs may attempt to torpedo you when surfaced - be careful!) but keep an eye out on the tactical map for destroyers, or worse - planes. Crash-dive as soon as you spot them.
Around this time, have I-26 look around for the USS Denver. If you can spot it, change course and engage the light cruiser. Ensure the cruiser's destruction with four torpedoes in her hull, but once you make the shot chances are the enemy will wise up to your presence and try to eyeball (yes, the computer can cheat and sink you with planes without using sonar) a depth charge hit - so make your first spread count.
Once you've sunk the Denver, the only thing left should be the Enterprise and the DeHaven - which is a Fletcher-class destroyer and should be close to the Enterprise. I-25 should spot it shortly and perform the head-on attack to sink the DeHaven and complete the hidden objective.
Once the DeHaven is no more, you can try and surface to engage the last PT boats as you close in on the Enterprise. They may attempt to torpedo you, but so long as you don't surface too close to them, you should be able to avoid any torpedoes the Elcos send at you. The Elcos, unlike the Japanese Gyoraiteis, lack artillery pieces. This means you can use the deck gun and machine gun against them with impunity.
If you've surfaced to deal with the last PT boats, the only American unit left standing should be the Enterprise. If you're on the surface, the Enterprise may decide against launching depth charge planes against you. If it does not, take advantage of its generosity and torpedo the carrier to end the mission.
or you can use the method i did.
take both subs to level 3, just above crush, point both just ahead of enterprise. if ships come near you crash dive. keep switching back and forth between subs to check surroundings. once you get to 1.5 km out. go to level 2, launch 4 torps from each sub. aiming slightly ahead of carrier.
northern sub: crash dive, reduce speed and aim ahead of carrier.
southern sub, turn on free move and torps and have him attack carrier.
northern sub, head for front of carrier. if none of the random torps you fired hit, you only need 1 too, restart. when you get to 1-0.7km go to level 1 and launch all 4 torpedos. with at least 5 hitting the carrier, it will sink
[Single Player] Beat the Submarine Challenge mission set from the Single Player menu.
Mission 1 – Crucial Cargo:
Go to crush depth and get to the middle of the convoy. All of the escorts are on the outside, so this is the safest place. Hop up to periscope depth and find the two target ships (gold indicators) and hit them with torpedoes. Two apiece and you are done. This shouldn’t take more than 5 minutes tops to beat.
Mission 2 – Periscopes Threatening:
The destroyers are your primary target because they are the only ones who can hit you with depth charges. Take them out first, firing torpedoes at a range of 0.4-0.5 for best chance of hitting. Two per destroyer should be sufficient. The battleship is slow and an easy target, but the cruiser can be a pain since it is faster than you are. You will have to bracket it in torpedoes and try to get a couple simultaneous hits for best effectiveness. Hitting it in the rear half of the ship is much more likely to damage the engine, which should be your primary goal. A stopped ship is an easy target.
Mission 3 – Coup de Grace:
Set your northern submarine to full speed, just above crush depth, due east and slightly north. Use your southern submarine as a distraction to pull the escort ships south. Note that you will be hit almost immediately by planes, if you want to avoid that go to crush depth with your southern boat immediately, but don’t stay there. Spend most of your time in the southern one messing with the escort to ensure they stay near you. The northern boat you want to get on the far (eastern) side of the carrier and slightly north, so drop it to crush depth at about 2 miles out and then turn it toward the carrier when you are past it. At about 0.7 miles from the carrier, go to periscope depth and you should be around 0.2-0.3 miles from the carrier by the time you can fire torpedoes. Hit with four pretty much simultaneously on the same section of hull and the carrier will sink. In case you miss with one, turn and hit it with your two rear tubes as well. If you fail to sink it at that point, your best bet is to restart rather than wait around to reload.
