== Description ==
<!-- ''Write an introduction to the article in 2-3 small paragraphs. Briefly tell us about the history of the development and combat using the weaponry and also about its features. Compile a list of air, ground, or naval vehicles that feature this weapon system in the game.'' -->
'''37 mm/50 Modèle 1933''' was designed as a successor to the [[37 mm/50 model 1925 (37 mm)|37 mm Modèle 1925]] to address newer aerial threats, but it failed to meet expectations, leaving the French Navy with a grossly outdated gun, struggling to deliver enough firepower to counter expected threats.

The '''{{PAGENAME}}''' is a twin-mount high-angle gun, originally designated for use against aircraft. However, lacking the {{Annotation|HE-TF|High-explosive with time fuse}} or the rate of fire needed to counter such threats effectively, its best use is against coastal vessels, particularly Motor Torpedo Boats. Requiring a direct hit on target and having a relatively small explosive filler, the HE shells of this gun have very limited damage potential. Still, with two shells flying in parallel, it is still likely to inflict visible damage against softer targets.

== General info ==
<!-- ''Tell us about the tactical and technical characteristics of the cannon or machine gun.'' -->
The gun is deployed on a unique twin-gun mount, firing both of them every 2 seconds with an Aced crew. It can engage targets in angles of +80/-8° and a guidance speed of 20°/s horizontally or 15°/s vertically.

=== Available ammunition ===
<!-- ''Describe the shells that are available for the weapon and their features and purpose. If it concerns autocannons or machine guns, write about different ammo belts and what is inside (which types of shells).'' -->

== Usage in battles ==
<!-- ''Describe the cannon/machine gun in the game - its distinctive features, tactics of usage against notable opponents. Please don't write a "guide" - do not impose a single point of view, but give the reader food for thought.'' -->
Being grouped with the Secondary armament or Anti-aircraft armament, AI gunners will use it to typically engage aerial and surface targets alike. Lacking timed or proximity fuses means that the weapon will really struggle to damage aircraft, being forced to directly impact the airframe to detonate. The best potential target for this gun is small coastal vessels, notably Motor Torpedo Boats and some of the small, unarmoured Motor Gun Boats, but an average muzzle velocity combined with a low rate of fire make even that a non-trivial task. Generally, the gun is best thought of as a support weapon of opportunity, rather than something reliable.

=== Pros and cons ===
<!-- ''Summarise and briefly evaluate the weaponry in terms of its characteristics and combat effectiveness. Mark pros and cons as a list.'' -->

'''Pros:'''
* Good guidance speed

'''Cons:'''
* Low rate of fire
* Low explosive filler
* Only a single type of ammunition - High Explosive
* Despite of being anti-aircraft gun, lacks timed fuse

The 37 mm/50 Modèle 1933 gun was developed for the Marine Nationale based on the [[37 mm/50 model 1925 (37 mm)|Modèle 1925]]. However, compared to foreign equivalents, such as the [[Bofors L/60 Mark 1 (40 mm)|40 mm Bofors]] or the [[2pdr QF Mk.IIc (40 mm)|Pom Pom]], it was inferior in terms of rate of fire and damage potential.

In 1930, the design for the [[Le Fantasque (Family)|Le Fantasque class]] contre-torpilleurs called for improved anti-air capabilities, in response to rapidly advancing aviation technology. The design specified two twin automatic 37 mm guns. The development of this new automatic variant proved difficult, with the vessels initially commissioned with older, single-mount [[37 mm/50 model 1925 (37 mm)|37 mm Modèle 1925]] guns.

The gun featured a conventional sliding breech mechanism and was fed from boxes containing six cartridges. This design resulted in a maximum theoretical rate of fire of only 30–40 rounds per minute per barrel, a rate that was quickly deemed insufficient against the rapidly advancing aircraft performance of the 1930s. This led to the creation of the 37 mm ACAD (Automatique Contre-Avions Double) Modèle 1935, a twin fully automatic gun designed to achieve an unprecedented rate of fire of 200 rounds per minute per barrel. The ACAD featured remote power control (RPC), significantly enhancing its capability against the latest high-performance aircraft. The new, ultimate design in the family was tested on the [[Arras|Arras]]-class sloop Amiens from 1936 but failed to see widespread adoption before the Fall of France. Instead, the 37 mm/50 Modèle 1933 became the weapon of choice for the navy, with hundreds manufactured and used until the end of the Second World War and beyond, with aviso La Grandière and cruiser Tourville being one of the last vessels utilising this gun in 1950s.
