True, but being as long/er does not necessarily mean more displacement which by current(?) (WWI/II) standards sorts ships into their classification if they all have turrets.
we make battleships totally invulnerable to SNAC hits to the hull ... but we add a funny little canyon spiked with turrets - where a bomber has to fly through - in order to hit a hole as large as a - how did luke skywalker put it? - as easy to hit as a womp rat or so ....
if you manage to hit that little hole, which is as large as a pilot - and only from a certain angle ... the battleship takes deadly damage - if you fail that .... you cannot do damage.
it would add a lot of ... fun ... to the role of bombers - considering that they woudl be forced to get into solaris range for certain hehe
on the subject of bret BB being a pocket BB - that might be the case ... - the ship is as small and compact as a light battleship - averagly armoured ... but equipped with a medium powercore, which gives it an edge over really light battleships .. it is still able to strafe long range fire quite effectivly - but lacks the high mobility of ... lets say an osiris.
considering its size and the fact that it has a medium core - it sure is technologically advanced compared to some other ships.
