Would a superpower Royal Navy have developed an equivalent to the Ticonderoga class?
Short answerVery likely, as a radar-centred air-defence cruiser probably closer to an enlarged Bristol concept than a direct copy.
NotesA British equivalent to the Ticonderoga class is highly likely in this superpower counterfactual. The role would be fleet air defence rather than a literal copy of the American hull. The resulting ship might follow an expanded Bristol lineage. Its final form would depend heavily on the radar outfit, since the sensor system is central to an air-defence cruiser's identity.
