During an attack by pirates on the facility, Lavak's ship was undergoing repairs and the facility needed three freighters to carry the dilithium crystals it required. (TNG video game: Starfleet Command III)
For this mission, jump to warp until you can make it to one of the drydocks under attack. You will unfortunately lose a drydock trying to make it and you should tell the freighters to maintain course when prompted to do so; if the freighters make it in time to fight the pirates, you have more firepower to take out the enemy. Also, you get reinforcements from the shipyards several minutes into the mission once Lavak's singularity plant comes back online.
