If we count purely based on starfighter class, Armada already has 6 more options for squadrons than a game based solely on fighters (X-Wing) did at this stage in its life.
If we accept that wave 3 and 4 are actually one wave (because they are) then that number increases to 8.
I'm not trying to take sides on the issue of squadrons overwhelming a game based on capital ships, but I found this interesting.
