UBOAT Attack on Aruba

The mission goal is to destroy 3 oil tanks on the ground with the deck gun.
It was a long journey so I decided to teleport there.
As I got close I realized it would be daylight so I diverted to a longer approach from the north to have me arrive under the cover of darkness.
As I approached I detected several ships including tankers and some Fast Attack MTBs. I fired torpedoes at the MTBs first but even with the torpedo depth setting at 1.5 meters they missed.
I fired one torpedo each at several of the tankers and sunk them.
One MTB then headed towards me so I fired a T5 torpedo at it and sunk it.
I then surfaced and fired the deck gun at 3 oil tanks on land to complete the mission. There were 3 others close so I destroyed them although no points were awarded.
I set my course to escape as quickly as I could and the remaining MTB did not follow.
After successfully egressing I teleported back to base.
Summary: 3 oil tankers on ground successfully destroyed, 3 Tankers and 1 MTB sunk, tonnage: 22,278
