A secure Indian Ocean could provide a holding area for ships supporting the Mediterranean war. Capital ships could pass south through Suez when they were not needed at Alexandria. This could make them harder for frogmen to reach, although their return through the canal might become easier to predict. Floating docks and other mobile support facilities could move from Singapore because Britain would no longer need the same capacity for a potential Far Eastern fleet. Japan could bring its own supporting infrastructure as well. These arrangements depend on the different operational conditions of the counterfactual.
