Type 23 and Type 31 frigates provide a modern comparison for the practical limits behind naval doctrine. A forward-based ship cannot depend on returning home for every maintenance task, so its equipment must be supportable where it operates. That requirement also creates a security tradeoff because foreign dockyard access can expose sensitive systems. The example turns doctrine from an aspiration into a question of maintenance capacity, risk, and sustainable presence.

A modern Royal Navy comparison shows why forward-deployed ships must be supportable abroad without exposing the most sensitive systems.
