The Dome Ships are described by the Andalties ( )as being more than a match for anything the Yeerks have, still it's implied that when this is said Blade Ships weren't widespread, in fact I got the impression that the one Elfangor sees in TAC was the first and that it had been designed with Alloran's ship building expertise, but I believe this theory was disproven at some point in the series.
The first Blade Ship is built in the Hork-Bajir Chronicles. By the beginning of the canon series they would be much more widely disseminated.
Also I believe the Blade Ship does hold bug fighters, I'm thinking two for some reason and does anyone else think it looks an awful lot like a klingon ship?
If the Blade Ship only holds two Bug Fighters, how come there are always so MANY Bug Fighters zipping around. Maybe it's just my mental block, but I always figured there were enough Bug Fighters for a small "swarm". At least a dozen or so.
Which, I guess, wouldn't make sense if the Blade Ship is only 8 or 9 times the size of a Bug Fighter. Then again, as Esplin said, is that length or overall size?
Also, is there a Pool Ship in orbit over Earth the majority of the time, or just when Visser One is there?
