Why not?
You could counter it with longer downtimes when destroyed.
Depending on AF size,
why not having a mix of 2-4 mannable .50cal pintlemounts in sandbagpositions,
2-4 37/40mm manacks
and on large AF additionally one or two AAA, like 88mm? Controllabe like the single AAA on carriers, i.e. slow traverse and elevation.
Downtimes for .50cal could be 2-5 minutes, downtime for large cal AAA (the cannon) dunno... longer than the 37mm right now. Maybe twice.
Just my 0.2...
