Battlestations: Pacific/Sub on Patrol

This mission obviously relies on your skills as a submariner. However, unlike Meet the Germans, it is rather easy. Try to upgrade to the Gato-class; it has a large number of torpedo tubes both fore and aft, and this allows for some error in taking your shots.

Primary Objective
 * Sink all cargo ships.
 * Disable the specified Japanese base facilities.
 * Sink the Kumano.

Secondary Objectives
 * Sink the convoy's destroyer escorts.

Hidden Objectives
 * Steal the Japanese recon plane.

This rather straightforward mission begins with you attacking a lightly defended Japanese convoy. The convoy is escorted by two destroyers, both of which can be sunk by head-on passes or through other means. Be aware, however, that your sub will take damage if you decide to go to depth level 3, due to a damaged hull. Avoid diving deep and instead try to outmanoeuvre the destroyers. Try to get them to run into the carcasses of the ships you just sunk and delay them enough for you to set up your next shot. Focus on the destroyer escorts and sink both of them before moving onto the convoy.

The convoy itself has no artillery, so if you manage to sink the two escorting destroyers have your sub surface and deal with the enemy using your twin deck guns.
