Saint Chamond designed the turrets using the "Dunkerque" turret, which the company had also developed. A small cupola on top of the turret held a machine gun. An even smaller cupola on top of the turret held a machine gun. Aiming was by periscopes located on the turret and cupola. The second shell penetrated the barbette of the aft superfiring turret. Is were outfitted with a ventral gun turret position. Each turret had rangefinder under an armoured hood at the rear of the turret. Snorkels were mounted on the rear of the turret. It had the forward dorsal turret and other armament and airframe advancements. This consists of four 9M113 Konkurs missiles mounted on the turret. The ammunition sits in two trays located on the turret floor rear. Two superfired over the forward main battery turret and the third superfired aft. Armor was weakest on the rear of the turret. This allowed for a third twin 4.5-in Mk VI turret to be mounted aft. The torpedo struck "Gneisenau" in the vicinity of the rear main battery turret.
