(He doesn't say "I've been reading up on your starship" !!!)
Couldn't he have meant "I've been reading up on starships (of this class)"?
The plural could have referred to multiple ships of a single class, rather than multiple classes.
And I'm sure the entire ship isn't covered in a single manual.
Just my two cents
