After a discussion with the Somtaaw Kiith-Sa about the derelict retrieved in the Outskirts of the Hiigara System, the Kuun-Lan arrives to find that their Research Ship is in some sort of danger after they receive a garbled communication upon exiting hyperspace. They soon discover various Turanic Raider ships guarding it while they wait for a larger force to arrive and board the Clee-San. Knowing that all knowledge about their ship designs (such as the Acolyte Fighter Drive) will be used by the Raiders, the Kuun-Lan moves to take out the guard fleet. They soon discover that there are mines surrounding the Clee-San and they are producing a jamming signal. Tactical recommends sending in a Mimic to establish a link so that the Clee-San's communications can be heard. With the Clee-San rescued, the Kuun-Lan hyperspaces off quickly before the Turanic Fleet arrives.
This is probably one of the most easiest missions in the game. Begin by putting all your Acolytes and ACV's on guard duty with the Kuun-Lan and tell your workers to start harvesting. If you don't have a Processor in your fleet, now would be a good time to build one. Once it has been built, set it to guard your Workers. Now, move the Kuun-Lan straight across the map towards the ping in your sensors manager. At some point, you'll get a message about a mine field nearby: use your ships to take out any mines you see. Also, use your ships to take out any Turanic Raider Fighters and Corvettes in the area, along with the Minelayer corvette. When you get near enough to the Clee-San, you will see the ship being boxed in with a globe of mines and if the Clee-San moves, all mines will activate and destroy the ship. Send a Mimic in (you may have to move it around a bit) to establish a link between the Kuun-Lan and the Clee-San. Destroy the mines marked in the sensors manager, then repair your fleet and hyperspace off.
If you do nothing whatsoever after completing the Mission Objectives, the Turanic Fleet will hyperspace in with a huge fleet of fighters, corvettes and Ion Array Frigates. You will be unable to win this battle so don't bother trying.
