The '''SA46''' is a 120 mm cannon made for the [[AMX-50 Surblinde]], [[AMX-50 Surbaisse]] and the [[AMX-50 Foch]]. These tanks were all prototypes which were ultimately abandoned as the cost of producing one was one of the obstacles the French Army had to face. The other one being the development of stabilized shaped charge shells (HEAT-FS) and its devastating effects on heavy tanks.

While testing the AMX-50s, it was suggested that they performed better than the US and the USSR counterparts, the M26 Pershing and the IS-3 respectively, although both France and Germany had to accept the project for its development to continue. As France was ready to accept it, it wasn't the case for the FRG as they wanted more lighter and nimbler vehicles, which the AMX-50s failed to achieve.

First way to use the SA46 is to find a good vantage point and wait for unsuspecting enemies to cross the user's cannon. The 6 second autoloader allows for rapid shots to be taken if the first one misses or does not instantly destroy the target. This is only the case with the [[AMX-50 Surbaisse|Surbaisse]] and the [[AMX-50 Surblinde|Surblinde]], as the [[AMX-50 Foch]] lacks an auto-loader and therefore, more accuracy is required. Unlike the AMX-50 Foch however, the Surbaisse and the Surblinde both have oscillating turrets which allows for very fast turret rotation, which is a trait shared with many other oscillating designs.

The second way of using the SA46 is to flank enemies and rush them.

This way of using the cannon however, is not recommended if the user is using the AMX-50 Foch as the lack of a turret and an autoloader will prove to be an obstacle that one cannot scale that easily.

Description

The 120 mm SA46 is a French cannon made for the AMX-50 Surblinde, AMX-50 Surbaisse and the AMX-50 Foch. These tanks were all prototypes which were ultimately abandoned as the cost of producing one was one of the obstacles the French Army had to face. The other one being the development of stabilized shaped charge shells (HEATFS) and its devastating effects on heavy tanks.

While testing the AMX-50s, it was suggested that they performed better than the US and the USSR counterparts, the M26 Pershing and the IS-3 respectively, although both France and Germany had to accept the project for its development to continue. As France was ready to accept it, it wasn't the case for the FRG as they wanted more lighter and nimbler vehicles, which the AMX-50s failed to achieve.

General info

The SA46 is a 120 mm cannon exclusively made for the AMX-50-120 and its variants. It is a very devastating cannon which can destroy most of its opposition with a single shot. The high velocity, coupled with the heavy weight of the projectiles guarantees massive amounts of spalling after penetration.

Even though, most users will be more comfortable with using APBC only, one should also think about grabbing some HE rounds as they'll make short work of not only light vehicles, but some medium vehicles as well, thanks to its 4,650 g of TNT filler. If one is worried that their round might over-penetrate the target, using the HE is a good and efficient alternative.

Usage in battles

The SA46 is a very destructive cannon, capable of destroying most of its opposition in a single shot. This, coupled with the fact that the cannon is mounted on tanks that have an oscillating turret and two of them are equipped with a 6 second autoloader, makes it amazing at fulfilling multiple roles.

Sniping

First way to use the SA46 is to find a good vantage point and wait for unsuspecting enemies to cross the user's cannon. The 6-second autoloader allows for rapid shots to be taken if the first one misses or does not instantly destroy the target. This is only the case with the Surbaisse and the Surblinde, as the AMX-50 Foch lacks an autoloader and therefore, more accuracy is required. Unlike the AMX-50 Foch however, the Surbaisse and the Surblinde both have oscillating turrets which allows for very fast turret rotation, which is a trait shared with many other oscillating designs.

Flanking

The second way of using the SA46 is to flank enemies and rush them. As the SA46 has very good characteristics and is used in conjunction with an oscillating, autoloading turret (with the exception of the AMX-50 Foch), makes it good for dispatching a whole squad of unsuspecting enemies. This way of using the cannon however, is not recommended if the user is using the AMX-50 Foch as the lack of a turret and an autoloader will prove to be an obstacle that one cannot scale that easily.

Pros and cons

Pros:

  • Strong APBC rounds; capable of destroying most of its opposition in a single shot
  • High velocities for both of its rounds
  • HE rounds carry 4,650 g of TNT filler

Cons:

  • Cannon is very long and hard to conceal

History

The AMX-50 is a heavy tank project which was jointly developed by France and the FRG (Federal Republic of Germany) in 1949.

In July 1945, in the aftermath of liberation, the General Staff expressed the need for heavy tanks with national design. As the tensions with the USSR were rising, and with the results of the last world conflict, the French Army started presenting precise specifications of what the future main tank of the army would be. The tank had to be comparable on several points to already existing machines, and it was requested that the power of the cannon was at least on par with the German 88 mm cannon used by the Tiger II, but it was also requested that it would have the mobility of a T-34 with the armour of a Panther.

Four prototypes were presented, but only one was accepted, which was the one that the firm AMX (Ateliers de construction d'Issy-les-MoulineauX) presented;

  • AMX 50
  • AMX 50 Surblindé (over-armoured)
  • AMX 50 Surbaissé (lowered)
  • AMX Foch

During the testing of these prototypes, it was quickly noted that they were superior to its US and USSR counterpart, the M26 Pershing and the IS-3 respectively. But the Americans did not want to fund a project that would not be adopted, so it was necessary for two countries to accept the project. As France was getting ready to accept it, it wasn't the case with the FRG, which was inspired by the doctrines of the ex-general Heinz Guderian , a supporter of lighter and faster tanks. In addition, the development of new technologies and capabilities in the field of missiles and shaped charge shells would make the tank's massive armour obsolete and unsuitable for a future large-scale conflict.

In the end, the three major obstacles which were the price, weight and the continuous development of HEATFS, weren't easy to scale, so the project was abandoned.

Media

Excellent additions to the article would be video guides, screenshots from the game, and photos.
