" We have determined that the satellite uplink site is powered by a hydrothermal power station located North of the site.
The destruction of the power station will severely delay operations at the uplink site.
Mission 13 - Thermal Power Strike
Fly out and destroy the power station. "
NOTE - at the beginning of this mission you are prompted to save the game. This is a clue that the campaign is near the endgame. From this point on you can only save when prompted.
The defenses are pretty strong and I couldn't survive this mission.
