Ok so I have lost each mission so far as the imperial against this beast!
The following is the 2 lists I am working on to take it on next.
Any comments suggestions?

List 1: Bring BIG gun
Wanted a Raider but couldn't get points to work.
TAdv: Maarek Stele [Required!]
-- Marksmenship, Cluster Missles

TF: Black Squadron Pilots x 4 [Required!]
-- Veteran Instincts

Gozanti Cruiser:
-- Vector, Ordnance Tubes, Adv Homing Missiles, Docking Clamp

Gozanti Cruiser:
-- Ion Cannon Battery

Idea is to use the Cruiser to carry the 4 Black TFers into the battle.
Letting them lose when close enough. Little extra protection going in.
Then use its weapons to target and take out satellites.
2nd cruiser used to target rebel ships to ionise them
And Maarek as opportunist!.

List 2: Seek n Destroy
TAdv: Maarek Stele [Required!]
-- Marksmenship, Cluster Missles

TF: Black Squadron Pilots x 4 [Required!]
-- Veteran Instincts

TP: RedLine
-- Engine Upgd, Acc Corrector, Extra Muni, PTorpedoes, Homing Miss

TPh: Sigma Squadron Pilot x 2

Maarek and the Black Squadron Pilots go after the rebel ships.
RedLine and both Sigma Squadron Pilots go after the satellites.

I'm not sure but it sounds like you're playing the corvettes campaign?

Yes should have said that. The 3rd mission.

IMHO, bringing two Gozanti to a 190 pts game is a not optimal idea.

aye a bit much but I want to shock him a bit. Maybe he will make some mistakes on seeing to cruisers coming at him.
