In ours. The tendency has been toward faster maneuverable ships instead of heavy boats of mass destuction for long, destroyer class was literally an anti-heavy ship weapon and is nowaday so efficient that almost no heavy capital ships are built other than carriers, dreadnought almost doesn't exist since long, and the last battleships in the world where decomissioned in 1990. Same goes for intermediate heavy like cruiser and battlecruiser. Frigates and Destroyer own the sea now.
This is beyond a simple SCB fix though. They need to change a lot of the fundamentals of combat to make this work.
I've been a fan of increasing the ability of small ships to disable large ones for a long time, because the vertical progression model just leads to everyone using relatively few ships (Anacondas everywhere) once money becomes no object. SCBs aren't going to make this happen though, and just reducing the survivability of the larger ships through a simple SCB limitation is going to mean that people won't use those ships in open.
The simple answer would end badly in my view. They need to take a pass over the entire combat model.
