khm, Perfide Albion...
Many years ago I was inspired same idea - cured Mers-el-Kebir, Syria campaign of 1941, Madagaskar and Djibouti, Torch landing... And even succeed issuing two-parts article about Syria Campaign in Soviet aviation magazine.
Then, after releasing of SH3, I tried to create the my first model - french submarine 'Iris'. It was a great effort, but, finaly happened nothing due impossibility to arrange the turnable torpedo launcher. On my opinion - this is key feature of french submarines. So, I suspended this model for the time beigh.
