Matching a hypothetical European navy to regional duties

The hypothetical European force has four regional commands: Atlantic, Mediterranean, Baltic, and Black Sea. The Atlantic and Mediterranean fleets would be the largest because they would also carry responsibilities beyond Europe. The proposed Atlantic fleet would cover the Pacific, while the Mediterranean fleet would extend into the Indian Ocean and Gulf. Carriers belong with these ocean-going forces, alongside frigates for escort and destroyers for air defence. Conventional submarines would support defence, nuclear attack submarines would provide global reach, and missile boats would suit the enclosed seas. Auxiliary numbers would follow the patrol stations and commitments assigned to each fleet.
