The intention is to keep them identical, with improvements applied to one ship being retrofitted to the other in due course. Prince of Wales has benefitted from lessons learned during the build of QE, which lead to the build time being much reduced. They are supposed to alternate in the same role, so they have to maintain identical capabilities, though over time any modifications will leap frog from one to the other.just curious if they're meant to be like identical, or if there're slight design changes between the two?
