1924 - France class reconstruction, 1934
The French naval staff have long been concerned about the poor stability of the two France class battleships. To correct this, the class will undergo a partial reconstruction in 1934-35. They will recieve bulges, new engines, a new bow, a taller torpedo bulkhead, and additional electronic gear. As a result of the bulges, their draft is reduced by 10cm, and there is a corresponding increase in freeboard. They are expected to enjoy substantially increased survivability as a result.
