330 mm50 Modèle 1931 — France’s Dunkerque‑Class Quad‑Turret Gun

Описание: The 330 mm/50 Modèle 1931 was the French Navy’s main gun for the Dunkerque‑class fast battleships and is best known for its distinctive quadruple turret layout. NavWeaps lists a practical rate of fire of 1.5–2 rounds per minute, noting the intended ROF was 3 rpm but shell-handling arrangements did not achieve the designed figure.
​

For “numbers hooks,” NavWeaps gives a SAPC muzzle velocity of 2,854 fps (870 m/s) (with HE listed at 885 m/s) and provides range tables showing about 45,604 yards (41,700 m) at 35° elevation. Wikipedia reinforces that the gun achieved great range with an elevation limit of 35°, implying very high muzzle velocity, and it explains the quad turret was internally divided into two twin groups separated by an armored bulkhead.
​

This episode focuses on what made the 330mm/50 so “French”: compact forward main battery, high velocity, and a turret concept built to concentrate firepower while managing risk inside the mount.

Pinned comment (engagement)
Quad turrets: smart concentration or too risky if one turret is knocked out? Comment SMART / RISKY.
