British nuclear cruisers reshape the Commonwealth fleet

What if Britain built six nuclear-powered cruisers beginning in 1955?

They would encourage nuclear carriers, missile cooperation, Commonwealth basing and submarine programs, and competitive European adoption of naval reactors.

A Royal Navy decision to build six nuclear cruisers in 1955 would likely carry nuclear propulsion into the next carrier generation and reinforce a global-fleet strategy. Missile development would become a major choice, with American systems offering a faster path than an expensive new British equivalent. Commonwealth ports would need to accept the ships, while Canada and Australia would gain stronger reasons to pursue nuclear submarines using British designs. French and perhaps Italian imitation could normalize naval reactors in Western Europe and alter public and governmental attitudes toward nuclear-powered warships.
