The 340mm/28 Modèle 1881 gun was a heavy

naval gun of the French Navy

.

History

The type was used in single mountings on the ironclads of the

Hoche

.

Railway guns

Eight guns were converted from naval use to

railway guns by Schneider and designated Canon de 340 modèle 1881/84 à glissement. The conversions were ordered during 1917 but they weren't delivered until January 1919 after the war had ended. The guns were suspended from two six-axle rail bogies and used carriage recoil known as the glissement system. The guns had no traverse mechanism so aiming was done by drawing the guns across a section of curved track.^[3]
