This gun was quite successful as a main armament for light cruisers. However, the dual-purpose version intended for use as a secondary armament on the Richelieus was far less successful, proving almost unworkable at an elevation greater than 45 degrees. Its rate of traverse was inadequate for the antiaircraft role and its dual feed system was prone to jamming. The original maximum elevation of 90 degrees was reduced to 75 degrees and several of the guns were replaced with 100mm antiaircraft guns.
