What were the missile systems proposed for Jean Bart?
The book only mentions the Terrier, but that seems to be separate and later from the A-E proposals. The launching ramps seem to indicate something else (3 ramps for Proposal A for example). I'm just wondering if the system wasn't something like the Oerlikon-Contraves RCS? There was a naval version proposed and Friedman has a drawing of such a layout for a British export cruiser for Venezuela. Not sure on dates, but the RCS series was still being developed around 1957-58. Its smaller missile and launcher could more easily explain the kinds of high magazine rounds quoted for these proposals.
Hood question about the Proposal A made me think if the French were considering buying Sea Slug which originally was meant to have a triple launcher (the same one which was installed on the test ship Girdle Ness). This might be an interesting idea, although I don't think it was a real contender.
Think 1956-1958 era:
The French never seriously considered the British missiles system simply because by 1957-1958 the Seaslug system was still under early testing (aka non-operationnal & not "proven") and that for the French, the Seaslug system look much more "cumbersome" (system size & weight) that the US Terrier...
And by 1956-1958 the French "home-made" missiles under development (Masurca, Masalca...) was still on very early testing (prototypes phase).
So, for Jean-Bart as a BBG, the French only seriously considered the Terrier system
