The Canon de 90 mm Modèle 1926 was a light-caliber dual-purpose gun used as primary armament on minesweeping sloops and anti-aircraft armament on a number of French Navy cruisers and battleships during World War II.

Description

The Canon de Modèle 1926 had an autofretted barrel and a Schneider semi-automatic breech mechanism. These guns were carried in single and double, dual-purpose turrets.^[3]

Naval Use

Ships that carried the Canon de 90 mm Modèle 1926 include:

Land Use

In addition to the naval gun, a land-based mobile heavy anti-aircraft version called the Canon de 90 mm CA Modèle 1926 was produced. In 1939 a modified — shortened by 1 metre (3 ft 3 in) — version was produced as the Canon de 90 mm CA Modèle 1939. Both were produced in limited numbers and it is estimated that only seventeen were built before 1940. Both had a two-wheeled single-axle carriage with three folding outriggers. Guns captured by the Germans were given the designation 9 cm Flak M.39(f). The gun was also supposed to be used on FCM F1 super-heavy breakthrough tank, but never passed the prototype stage.

Ammunition

Ammunition was of fixed QF type. The cartridge was 90 x 674mm R with a 6.83 kg (15.1 lb) propellant charge and weighed 18 kg (40 lb).

The gun was able to fire:

High explosive - 9.51 kg (21.0 lb)
Illumination - Unknown^[4]
