The enemy ships are balanced around the ship you take as well as difficulty/fight rank, so it should be winnable with any ship if you're good enough. Most of the universe's capturable ships may make an appearance.

Minor secrets:
-It's also allowed to "hide" ships by docking them to the ship you take in... although for big ship combat this is of limited utility anyway
-If the local police/military/NPCs/etc kill ships, they still count for you. The mission will only choose border sectors to minimize this possibility.
-Fixed the mission appearing too frequently when the player stays in the same sector for a long time
-Slightly increased the difficulty at low fight ranks and slightly reduced the difficulty at high fight ranks when the mission is marked Average, Hard, or Very Hard
-Un-hardcoded a couple of text strings
