Battlestations: Midway/Periscopes Threatening

Primary Objectives
 * Sink the enemy fleet

Don't let the objective fool you. This can be a tough mission, but if you manage to win, you'll automatically get the gold medal, so that's good. The enemy fleet you must sink consists of:
 * New York class BB (x1)
 * York class CA (x1)
 * Fletcher class DD (x1)
 * Clemson class DD (x2)

The trick in this mission is to act quickly enough that you don't run out of air. If you run out of air and the battleship is nearby, you're going to get fried by its massive cannons. On the other hand, the battleship and the HMS York will completely avoid you until you surface and, therefore, are the biggest non-factors in this fight. The destroyers are obviously what should be on your mind.

Sinking the Fleet
Keep your periscope raised as you observe the enemy fleet. Keep track of which destroyer breaks formation and heads for you. Now is also a really good time to practice the head-on attack, as it really is the best way to sink an enemy destroyer. Doing so will allow you to act a little more freely, but keep in mind that you're going to run out of air, so you may want to start working on those bigger ships too.

One by one, the destroyer escorts will leave the formation and head straight for you. Perform the head-on attack to sink these menaces.

When you feel you can use a few torpedoes, get as close as you can and lodge torpedoes into the battleship in particular. By now you're probably running low on air, so you're going to want to start removing the surface threats. By now most if not all of the enemy destroyers should be at the bottom, so that should be that. Work quickly and don't forget to use the rear torpedo launchers to cause additional damage. Spread your torpedoes out and punch multiple smaller holes instead of one big one, especially in the enemy battleship. Sink the HMS York in the same manner to end the mission.
