The type was used on the Duquesne and Suffren classes of heavy cruisers as main battery, mounted in four twin turrets. The calibre of 203mm was characteristic of heavy cruisers as defined by the Washington Naval Treaty.
The type was also mounted on the Surcouf, which was designed as a submarine heavy cruiser intended to disrupt enemy supply lines. This flavour of the gun was fitted with mechanically actuated tampions to allow quick dive.
