hmmm, maybe it should be a Skirmish level ship. Those would be better escorts for an Omega of any variant. With Escorts, you can never have enough.
I don't think it would need the "escort" trait though as the Omega already has 6 AF. Maybe something with either missiles or beams as there primary to compliment the Omega's devestating short range barage.
In fact I think a light missile ship with a couple of AD out the front and sides would work real nice on a skirmish level ship. 2 AD of medium laser cannon out the front, 4 AD of missile out each side. 6 hull, 7 speed, 2 Intercepters and 4 AF. No secondaries.
Give it abour 14 Damage and around 18 crew with an appropriate threshold for each.
