French coasts are heavily fortified with artillery of various vintages. The most modern emplacements are those using the 340mm/45 Model 1912. Each of the five cancelled Normandie class battleships (laid down 1913, launched 1914, cancelled ) were to mount twelve, in three quadruple turrets. In some cases, these turrets have been retained for the coast artillery emplacements. Other emplacements use dual turrets. A total of 72 340mm/45 were made available to the coast artillery. And since the scrapping of the Danton class predreadnoughts, 40 245mm/50 Model 1906 have also been assigned to the coast artillery.
