Well, looks like a little bug in the following text file:

Main_EnemyGroups.txt

Find the file in the following location, under the folder where you installed StarFury:

\Campaigns\Campaign 2 - Border Wars

Open the file with any text editor and search for the word 'Stealth' without using single quotes. That find request should place you on a line with an entry value of "Fazrah Stealth Cruisers 1"

You now need to change one letter in each of three entries below that in the following lines

Group Enemy 1 Class Name
Group Enemy 2 Class Name
Group Enemy 3 Class Name

Each of these lines has a value of 'Fazrah Cruiser S' which is the problem, since either the S type cruisers don't exist or there's some bug detecting them even with Tachyon Sensors installed on your ship.

Change the S to a B and rerun the mission from a save game PRIOR to entering the Fitkil system. The change might conceivably work after you enter the system, but I wouldn't want to test my luck.

Now when you enter the Fitkil system, you should see 3 cruisers spawn clearly identified as belonging to the attack group "Fazrah Stealth Cruisers." Kill those 3 cruisers and voila, mission complete successfully this time.

Btw, I made the change, then reloaded from a save game prior to even accepting the mission to go kill the cruisers, having saved just before registering successful completion of the main story mission right before the stealth cruiser one. So, if you make the edit and find that loading within the Fitkil system, or outside of it after having accepted the mission doesn't work, then go back to a save game prior to accepting the mission.

Hope that helps.
