Star Wolf ---- got after Astarte by doing work for NSEF (New Empire). Stronger armor (5500), shields (2500) one more system (4) and one more turret (4) but one less heavy gun(1).
Lion Cruiser ----- after Astarte by working for the MSF (Old Empire). Armor 10000, shields 4000, 4 turrets, 4 systems 2 heavy guns, 750 speed, 33 maneuverability. And looks really COOL
BTW am I the only one, who was really looking forward to fly the Stalingrad class?
