Ace, Your entire analysis is biased
Here you think Dutch (zeven provincien CG)
For the Jean-Bart (BBG version), I think french
In your analysis, you want to delete all the aft triple 6" turrets
The problem is that the French have never really imagined remove all aft 6" turrets
(They considered only removing the aft centreline 6" turret)
And the French only hoped to use the Mk 10 launcher, not the Mk 4 one
You think technical capacity
I think real-tudies & real french (1950s-1960s) missile-ships projects
Do not forget that all french missile-ships of the 1963-1972 era (Dupetit-Thouars, Chayla, Kersaint, Bouvet, Suffren, Duquesne, colbert) all carried 1 launcher, 2 missiles-directors & 40 to 48 missiles, no more
Jean-Bart would never have embarked even 4 to 6 directors (this BBG conversion would cost too much for the french !)
