Gorgon is dedicated though . . . I was meaning something thin-skinned because it was never up armored and of course not the most efficient design. IMO, like I was advocating the aerodyne it would suffer the same non-atmo problems the Vengeance had per fluff.
Leopard CV is 2582? So its way before and for its time it was probably one of the first dedicated ASF carrier . . . rather than being a SC carrier.
Leopard-CV, 1,720 tons, 6 Fighters, first launched 2581 (~50 years after the first mech carrier model). became the most common fighter carrier in the IS. (which explains why it is IS general in the MUL from star league times all the way to the jihad.. and presumably right into the early republic, and dark age periods as well)
Vengeance, 10,000 tons, 40 fighters and 3 smallcraft, first launched 2682. dedicated carrier with limited weaponry. usually required escort by Assault Dropships for defense. MUL lists them as Capellan, Davion, and FWL during star league times, with comstar, Outworlds Alliance ,and mercenaries gaining them in the early succession wars. late succession wars they are IS general.
Titan, 12,000 tons, 18 fighters, first launched 2647. largest dropship fighter carrier pre-clans, at least by tonnage. doubles as an assault ship, and originally used as escorts for warships under the star league. Out of production following the 1st succession war due to the loss of the manufacturer's shipyards. virtually none survived in the IS by the 3rd succession war, likely due to overuse as a warship alternative. MUL lists them as Capcon, Fedsuns, FWL, Lyran, Hegemony, Periphery General, and Star League regulars and royals. early succession wars it is IS general (and calls out the outworlds alliance, suggesting they had rather more than normal.)
i'd say that in the 1st succession war, the IS had escort carriers already, so didn't need to develop any. though the fact the Combine had so few the MUL didn't list them for those era's suggests the Combine had to make do with mainly Leopard-CV's.
