Forward basing submarines without trapping them

Should submarines be forward based closer to the Gulf or South China Sea?

Forward basing is useful where it frees other assets, but placing a submarine too close to a likely crisis area can reduce flexibility and create risk.

A conventional submarine at the Falklands could cover the South Atlantic and free a nuclear boat for wider missions. That arrangement substitutes a regional asset where its shorter range is sufficient without tying the most flexible submarine to routine coverage. Basing a boat directly in the Gulf or South China Sea is much riskier because the base and its approaches may become an immediate wartime problem. Forward basing is useful when it releases scarce assets, but counterproductive when it traps them near a predictable choke point.
