For many battleships the stats are just weird. For example here the CR BS which is almost as big as the Rheinland BS. The Jormungand's small size at least has a thing which evens it out: Only one Class 10 forward (+ a mostly useless FWG), while every other Medium BS has 3 Class 10 forward.
Another BS which is way too big for its stats is - and always has been - the Sarissa (OC BS).
I suggest either shrinking them down a lot or making the CR BS a heavy BS and giving it the appropriate stats (more armor, more bots, slower...etc - as the OC already have a heavy BS shrinking the Sarissa down is probably the better choice, shrinking the CR BS would also be more fitting imo, keeping RP etc in mind).
I included some more BS, just for comparison. This is mostly about fixing the CR BS stats/size balance.
