Forward presence only works with enough ships and crews

Given its training and maintenance problems, is there a better system than forward presence?

Forward presence remains useful, but training and maintenance require sufficient ships and crews for sustainable rotations.

Forward presence requires enough ships and crews to sustain it. Announcing an overseas deployment does not supply the hulls needed to cover training and maintenance. River-class patrol vessels in the Far East provide a useful example of the approach. More patrol vessels would allow better rotations and make that presence easier to maintain.
