ok, 1 good Ursa pilot can take out an Orion, done it before, its even easier in a Sekhmet (that baby is fast for a bomber). Lets say instead of the Colossus we went with 50 wings of Myrmidons, thats 200 fighters. Armed with Helios in their 3rd banks, each Myrmidon only needs to get off 1 bomb that actually hits. Since the 3rd bank can support 2 helios bombs, each fighter can get off 2 bombs on their first run. Now, of course, some will get shot down, but Myrmidons are fast, maneuverable, and have decent agility, atleast 100 would get within 400 meters of their target, from which point their bombs are just about gauranteed to hit. Likewise, it only takes 6 good Myrmidon pilots to wipe out any conventional destroyer.
The Colossus woulda made for a better carrier than a frontline weapon.
