Japanese aircraft operating from British carriers are a possible later development, with rapid adoption considered unlikely while British purchases from the Americans are already being negotiated. American equipment for North Africa could travel across the Pacific and Indian Oceans without entering the Atlantic submarine convoy routes. Ships could sail more regularly where they no longer need to wait for convoy assembly. German merchant raiders would remain a threat, so vulnerable stretches could still require convoys escorted by older British C-, D-, and E-class cruisers. Japanese maritime patrol aircraft could reinforce positions around the Indian Ocean. Cooperation would also give Japan firsthand knowledge of British imperial operations, as its assistance during the First World War had done.

American equipment reaches North Africa through the Pacific and Indian Oceans
A friendly Japan opens a supply route that avoids Atlantic submarine concentrations, although German surface raiders still require escorts and patrol aircraft.
