## History

https://en.wikipedia.org/wiki/37\_mm\_automatic\_air\_defense\_gun\_M1939\_(61-K)

The Soviet Navy purchased a number of Bofors 25 mm Model 1933 guns in 1935, trials of the weapon were successful and it was decided to develop a 45 mm version of the weapon designated the 49-K. The development under the guidance of leading Soviet designers M.N. Loginov, I.A. Lyamin and L.V. Lyuliev was successful, but the army thought that the 45 mm caliber was a little too large for an automatic field weapon. In January 1938 the Artillery Factory Number 8 in Sverdlovsk was ordered to develop a 37 mm weapon based on the same design. The task was fulfilled by the chief designer of the factory, Mikhail Loginov, and his assistant Lev Loktev. Firing trials of the new 61-K were conducted in October 1938.

Competitive firing trials were conducted in 1940 between the 61-K and the Bofors 40 mm / 56. There were no substantial differences found between them.

During the Second World War, the Soviet front units were especially equipped with this weapon. The light and mobile gun proved successful in use. A disadvantage was the small number of around 700 copies available at the beginning of the war. The relocation of production to Plant No. 4 resulted in production slumps that could only be overcome from mid-1942. From the middle of 1943 over 6500 guns were available, this number remained almost constant until the end of the war. In the first phase of the war, the 61-K was also successfully used as an anti-tank weapon. The grenade penetrated 40 mm of armored steel at a distance of 500 m, which made it possible to fight the German Panzer Panzerkampfwagen II and Panzerkampfwagen III as well as the Czech and French tank types used by the German side.

German troops captured 61-K under the designation 3.7 cm anti-aircraft M39A (r) as anti-aircraft gun. In March 1944 there were twelve batteries with 138 guns; a total of 652 cannons are said to have been captured and used.

During the Vietnam War, North Vietnamese troops used both Soviet and Chinese versions of the weapon. In addition to the drawn variants as a single-barrel weapon and twin, Chinese anti-aircraft tanks Type-63 were also used. The weapon proved to be effective when used against air targets at low altitudes.

## In the Game

The M1939 was the first Soviet anti-aircraft gun in the game and appeared in demo 3. It differs in particular by the fact that it does a lot more damage in comparison to other AA guns , which is why it was for some in demo 4 OP because it was able to get planes from the sky with 2 hits , because the planes in total (HP + Armor) had only 20 hit points in Demo 4. It can also defend itself against light tanks better than other light anti-aircraft guns. It is also very cheap at 150. But it has a comparatively lower rate of fire. Otherwise, she shares the pros and cons of the AA guns.

### Pro

* effective against aircraft
* effective against infantry
* can also be dangerous for light tanks
* cheap for a AA gun

### Contra[1]

* cannot withstand much damage
* ineffective against medium and heavier tanks
* Stationary = easy Target for Artillery and Bombs
* you should have more of them to effectively fight enemy planes
* Due to their speed, the AA guns have a hard time to shoot a jet down
