Iceni has about the same AAA defenses as a Fenris, maybe a Leviathan.
Less. A Levi has 4 AAAf. A Fenris has 2. The Iceni has 0. Its closer to the Moloch, with just some blobs and flak. (except in Rebels and Renegades. In that scenario, its probably got as good anti-fighter defense as a Deimos).
However, it has MUCH better antifighter defense than an Orion (which has NONE in my books). You can fly along both broadsides, the front and the rear, and never come under fire from more than a single Terran Turret... The AAAf beams are on the top and bottom surfaces, and are worthless. the Orion has no flak to its name. (Except the Uhuru, which has flak instead of THT's).
I seem to recall that if a **** is in front of it the Iceni can let loose with all 3 BGreens . (someone correct me if i'm wrong) Oh and i read about someone stating that the Iceni is an unbalaced ship. (Do you really wannna start the whole Lilith debate all over again? )
No, the Iceni can bring a Maximum of two. The turrets do NOT have a 180 field of fire and cannot fire forward at all. The Iceni's frontal turrets are blobs.
