Alright, my fleet is based on stuff that could be used by the GA during the Second Galactic Civil War.
I can't find a length for the Ranger-class Gunship (
http://starwars.wikia.com/wiki/Ranger-class_gunship), so I'm gonna pull a random number out of my ass and say 200 meters. If that's been clarified somewhere, I'll adjust fire as necessary.
Wookiee is also nonspecific about the length of the Skipray 24r Blastboat, saying only that it's a little bigger than the original (
http://starwars.wikia.com/wiki/Skipray_24r_Blastboat). The original was 25 meters, so I'm going to round up to 30.
Going with XJ-7 model X-wings, with a length of 12.5 meters.
Breakdown is as follows:
Carrier (undecided, but it won't be engaging in combat)
1 Ranger-class Gunship for point defense (200 meters)
15 Skipray 24r Blastboats
90 XJ-7 X-wing Fighters
Each Skipray will be accompanied by 6 fighters. The Skiprays will serve as squadron leads, with squadrons designated Alpha through Oscar on the phonetic alphabet. For the purpose of this fight, each squadron will act as a cohesive unit.
