Actually id forgego the Strike carriers. You get the same Delta-Vs in bigger numbers by just getting fighter wings. And the Carrier itself grants no bonus to your fleet. Actually it is slower than the fighters, only giving marginal use to its Jump point, though jumping fighters behing enemy lines would be a new one. The firepower isnt really up to anything, and i wont even talk about its survivability, should the enemy actually deign it with some attenttion.
For raiders get battlewagons, they are actually a fine ship, and look into getting either Argents Crusaders or the Ghosts of Omelos as a raider fleet, that should give you more options without havint to go too LONAW heavy, though the Ghosts give you many nice options they arent really the standard raider fleet anymore.
