Question

When does a battlecruiser become a fast battleship?

Short answer

When its armor coverage and internal subdivision are sufficient for sustained battle-line service.

Notes

A fast battleship must be suitable for the battle line. Internal subdivision and armour coverage must both be sufficient for that service. Speed alone does not establish whether the ship meets the requirement.
