While in Casablanca, the French attempted to prepare the ship for action as much as was possible in light of limited infrastructure and the lack of many necessary parts to complete the vessel. The facilities there were not capable of completing the second main battery turret, nor were the Germans interested in allowing the needed armor plates and guns to be shipped there. Instead, to protect the ship's interior, the French covered the open barbette with concrete; the empty secondary barbettes received the same coverings. A makeshift fire control director was installed in 1941, but it proved to be unreliable and so an ad hoc director system was set up using shore-based observation points to triangulate targets for the main battery. Her anti-aircraft armament was slowly strengthened as guns became available and a search radar was fitted in 1942. Unlike her sister, "Jean Bart" was not targeted by British forces during this period.
