An enlarged Azores archipelago as an Atlantic naval base

If the Azores retained a much larger landmass, how strategically important would they be and what base might Britain build?

They would be highly attractive for Atlantic operations and could support a major base, subject to Portugal's ownership and the assumed political arrangement.

Larger islands in the Azores would offer an attractive position for a major Atlantic naval base. Portugal's traditional ownership and alliance with Britain remain part of the scenario. A British takeover during Spanish control of Portugal is floated as one possible route, with a long lease suggested as another. The imagined base would be substantial, though no detailed capacity or construction plan is specified.
