Looking at how they can mobilize eighty juggernauts and throw wave after wave of fighters at you with impunity, it wouldn't surprise me they have superjugs and thousands of fighter/bomber squadrons at their disposal.
Well they do actualy have thousands of fighters and bombers at they disposal . See 80+ jugg's can carry an aproximate
thats 20k fighters and bombers (ive put it at 250 fighters and bombers per jugg. However we do not know this for sure but we can safely asume it is a correct figure) .
Also i have a distinct feeling that the Jugg fleet was (IMO) the main force of the shivans. This is not to say they don't have a few dozen destroyer to boot . Or even 1 or 2 even larger more powerfull ships.
However assuming the shivans are all powerfull and have a capship inventory in the tens of thousands sounds pretty stupid to me.
And by all means do remember that the GTVA also in theory have thousands of fighters and bombers. However we never see them. Capella being a densly populated system should and could in theory hold a few thousand bombers and fighters. However i do not believe Capella was being used as a ship production equipment. We do know of other places that hold shipyards and have numerous (in theory) fighters and bombers .
About the whole squadron organization of the fleets and stuff it does seem a bit too human to boot. Perhaps something a bit different. However i would like to hear GTVA Command :"Were sending in a squadron of Aeolus cruisers to engage the enemy's 300 fighters and bombers. Rest asured pilot help is on its way we wont leave you to kill a kazilion fighters and bombers and few dozen warships on your own" Lol. thats never gonna happen .
