Why 31 Bay-class ships would not equal an amphibious fleet

What would Britain gain from building 31 Bay-class landing ship docks?

It would gain enormous lift and disaster-relief capacity, but Bay-class ships are logistics platforms without the command facilities or landing-craft density needed to turn that lift into a balanced amphibious force.

The calculation uses a standard capacity of 350 troops per Bay-class ship, giving 10,850 across thirty-one available ships. That is a nominal transport total, because ships assigned to logistics would reduce the number carrying troops. Tanks and containers are among the loads discussed. The Bay class would provide extensive transport and disaster-relief capacity, but it lacks the command facilities needed for the proposed force. Albion-class ships are described as carrying a similar number of Royal Marines while providing double the landing craft and the necessary command facilities.
