Where HMS Hood could receive a deep wartime refit

Where could HMS Hood receive a major wartime refit, and what would make that work possible?

Either the United States or Belfast, depending on timing, cost, and whether improved strategic conditions freed her from constant capital-ship patrols.

A deep Hood refit could take place in the United States or at Belfast. Nelson would need new engines and extensive work of her own, while Hood's destination would depend on the timing of her withdrawal from operations. If earlier battles removed Scharnhorst and Gneisenau and reduced Italian or French capital-ship pressure, Britain could release more heavy ships for reconstruction. Timing, cost, and the remaining demand for capital-ship patrols would decide whether the work stayed in Britain or moved to an American yard.
