Hello again!
I indeed forgot the light AA rangefinders, added below. The 13mm AAMGs shown in the original plans have been substituted with 25mm twins; as everyone (including the Vichy French within the limits of their possibilities) was trying to get rid of those quite useless guns and replace them with autocannon, I thought the Joffre would also have them by 1942.
Below a 1945 variant with more flak, some british-style radars and new planes (navalized Arsenal VB.10 and Nord N.1500).
Greetings
