Why Gibraltar would trap a War Plan Red expedition

An American attack on Gibraltar would require a large transatlantic fleet and amphibious train to defeat a fortress while British forces cut its supply and retreat routes.

Question

Could the United States seize Gibraltar in War Plan Red to break British imperial logistics?

Short answer

Only at extreme risk; the expedition would need a major fleet and amphibious train, then face a fortified siege while British fleets cut its supply and withdrawal routes.

Notes

Treating Gibraltar as the hinge of British logistics does not make it an easy target. A US expedition would have to cross the Atlantic with troops, tankers, escorts, and enough fleet strength to fight both the Mediterranean Fleet and British reinforcements. The Home Fleet could position itself between the attackers and their route home while British night strikes exploited a force whose location was known. Even reaching the rock would begin a costly siege against defenses built and repeatedly improved for that purpose. Capturing Gibraltar would still leave the expedition needing repair, resupply, and a way back through converging British forces, so the operation risks trading a major share of the US fleet for a temporary lodgment.
