Cyberia - Milestone 13

As the Transfighter proceeds closer towards the mainland, the Cartel forces seem to be rising in strength and variety. You have now arrived at one of their major outposts, and must deal with their defenses in order to pass through safely.

Walkthrough
A reoccurring threat during this mission (combined with the regular swarms of Hoverfighters) are the Gunboats that like to hide from your view behind the islands, only giving you a second or so after spotting them to react.

You'll start to see the munition dumps further into the islands, each of them housing defense turrets. The TF-22 will make a few passes around the area in order for you to take out as many of the dumps as you can.

Once you've cleared out the islands, you'll encounter the enemy submarine along the outskirts. It will fire a couple missiles as you approach it, and then you have a few more seconds to take it out. Accomplishing that will secure the area, and you can move on to the next mission.
