In Star Trek New Worlds Federation Mission 2: A Harsh Lesson, you face off against the orian pirates.
This planet is very rich in dilithium and the pirates want it for themselves. If the federation does not establish a colony here, the indiginous species - the Talbate will perish. Build up the colony, fortify it with defenses, get resoures off the world to the orbiting consititution class starship and see if you can find that odd building that was scanned from orbit. All while fending off the attacks.
