The240mm/50 Modèle 1902 gun was a heavynaval gun andCoastal defense gun of theFrench Navy.

The type was used on theDanton-class battleships as secondary battery, mounted in six twin turrets.

The guns were later used as coastal artillery after the ships were broken up, and served during theSecond World War, notably in theBattle of Dakar. One open-top twingun turret is preserved at the batteryCastelGorée, where it has been installed after 1934 to the older coastal defence armoured turret.

Two further examples in single open barbettes are preserved near the Jesus Christ Statue at Vũng Tàu in reasonably good condition. These emplacements were part of a system of coastal fortifications constructed inFrench Indochina during the early 20th century.
