context: The first four were laid in 1913, the last in 1914. Three ships were launched in 1914, the Languedoc in 1916. However, the events of the First World War forced to stop the completion of the battleships. The last ship of this type, Bearn, was launched already in 1920. Under the terms of the Washington Sea Treaty, the construction of all battleships was discontinued, but the terms of the agreement allowed France to rebuild Bearn into an aircraft carrier, which was completed in 1923-1927.
question: Why ships of the Normandy type were not in operation?
