U-Boat patrol line

U-Boat patrol line

This technically does classify as a Naval Battle, but not to a great extent.

You face 3 Type VII U-Boat. (The Type VII was the most widely produced U-Boat, built for the Kreigsmarine, during WWII.)

They are placed at a maximum of 15km away, thus giving you time.

Sounds easy, right? Yet, you guessed it, there is a catch.

You are escorting 3 transport vessels, and the amount of gold you earn depends on how many transports are still aloft upon completing the mission.

Completing this mission will earn you 1,440 gold.

Tips;
 * A U-Boat is an attack submarine, (*duh*), but they will still submerge/dive underwater during the mission. Use the same tactics for when facing the Soryu submarine.
 * A U-Boat is stronger than Soryu, though. (Soryu has only 2 torpedo tubes, whereas a Type VII has 4 torpedo tubes, and 3 76mm MGs)
 * You need a  minimum  of 400mm Lightweight Armor, and practically any weapon will do. (This is given the U-Boats need a wooden deck to submerge, so it trades armor for firepower.)
 * If all transprts are lost, then you failed the mission.
 * U-Boats will target you, but their primary objective is to sink the transports.
