Full Thrust Campeigns: Big vs Small ships

Given the current discussions about Large Ships versus small and
campeigns,
we need to examine this against the backdrop of how long the campeign
is.
  One player commented that if a destoyer squadron attacked a
battleship,
the battleship would only have to be repaired while the destoyers had to
be
replaced.  At the hieght of WWII the United States was pumping out a
victory
ship a week and a destroyer every two.	However, Battleships and
carriers
took much longer and cost a lot more.  The infrastructure costs for a BB
and
CV (i.e. Thrust efficiency cost) is proper and allows a DD squadron of
equal
value to destroy a capital ship.  The BB has some serious range
advantages
and these need only a slight adjustment in the costs and mass issues for
A
and AA batteries...
  Repairs to carriers in the Pacific were extraordinary and cost a lot
in a
brief amount of time.  Therefore, repair rules should obviously benefit
repairing an existing ship but only to a point.  Additionally a ship
yard
tooled for repair takes time to ramp up to construction and vice
versa...
