I forgot how to take take those cargo. But i sugest you to take lvl 13 cargo. Ships: Harriers Weapon: 2 Railguns armor: Platsteel/tritanium Shield: Spectral
use 1 ship to bait enemy ships by circling them. Keep the bait moving, so those railguns will not hit you. While the enemy firing at your bait, use the rest of your ships to kill them.
If you do it right, you will only lose 1 harrier or even you won't lose any ships
