Did France have a post-Lyon capital ship able to rival the British G3 and N3 projects?
Short answerNo. France was still trying to complete the Lyon class, which would arrive too late to shape a race already moving toward G3 and N3.
NotesNo French design comparable to G3 or N3 is identified. France’s immediate challenge would still be completing the Lyon class rather than leaping to a new generation. In this timeline, those ships would enter service only after the British projects were already changing capital-ship calculations. France would still be completing Lyon after British projects had moved the comparison to a newer generation.
