What could a unified NATO fleet of the 1950s look like if it used common new designs?
Short answerIt would likely combine British and American carrier, cruiser, and destroyer ideas, while frigates remained nationally built but more standardized in equipment.
NotesA standardized NATO fleet might use British light fleet carriers and American heavy cruisers. American destroyer leaders could operate alongside British destroyer designs such as an expanded Daring class. Frigates would resist full standardization because member states would still want to build their own hulls. Their equipment could become compatible without forcing every navy to adopt the same ship design.
