General info

Survivability and armour

The upper glacis of the hull and the upper part of the turret are the only well protected areas, which will give you good protection against most conventional rounds, especially from far ranges. However, the rest of the armor is very weak and can be easily penetrated by pretty much everything, and you will still be vulnerable against HEAT-FS, ATGMs, APFSDS and such. Your best bet is to flank the enemy and take them out with your auto loading gun before they can get a hit on you. If an enemy spots you, face them so they can only hit the front of the tank, and hope that they don't hit the very weak bottom portion of your turret. Try not to angle your tank as the sides can easily be penetrated. Since you have 5 crew members, with 2 in the front of the hull and 3 in the turret, and come equipped with a handy auto loader, you can take a few hits and lose a couple of crew members without having to worry too much.

Although heaver and not as mobile as the AMX 50 or Lorraine 40t, the SOMUA SM is still pretty mobile for a heavy tank. You will still want to flank the enemy as much as possible and take them out quickly with your auto loading gun, but don’t be afraid to take a few hits from the front. However, your reverse speed is pretty slow and will not save you, so watch out for that.

Main armament

Main article: SA47 L/58 (100 mm)

Give the reader information about the characteristics of the main gun. Assess its effectiveness in a battle based on the reloading speed, ballistics and the power of shells. Do not forget about the flexibility of the fire, that is how quickly the cannon can be aimed at the target, open fire on it and aim at another enemy. Add a link to the main article on the gun: {{main|Name of the weapon}}. Describe in general terms the ammunition available for the main gun. Give advice on how to use them and how to fill the ammunition storage.

Ammo racks of the Somua SM



  • Shells are modeled individually and disappear after having been shot or loaded.
  • Rack 9* (autoloader magazine) is a first stage ammo rack. It totals 9 shells.
  • This racks get filled first when loading up the tank and is also emptied first.
  • As it is equipped with an autoloader, manual reloading of the gun is not possible.
  • Once the autoloader magazine has been depleted, you can't shoot until the loader has restocked the autoloader. The restocking time is longer than the normal reload time of the gun. Take this into account when playing.
  • Simply not firing when the gun is loaded will move ammo from racks 1 to 8 into rack 9*. Firing will interrupt the restocking of the ready racks.
  • The depletion order at full capacity is: 9 - 1 - 2 - up to 8.

The small caliber of the MAC 31 machine gun makes it largely ineffective against all armoured vehicles but the ones with an open compartment. It still can be used to ping targets as a rangefinding help.

Usage in battles

Describe the tactics of playing in the vehicle, the features of using vehicles in the team and advice on tactics. Refrain from creating a "guide" - do not impose a single point of view but instead give the reader food for thought. Describe the most dangerous enemies and give recommendations on fighting them. If necessary, note the specifics of the game in different modes (AB, RB, SB).

Pros and cons


  • Same great gun that's found on the AMX-50 and Lorraine
  • Equipped with a huge 9-shell auto loader, making this one of the best tanks to attack multiple enemies at once
  • Due to the immense auto loader, this tank is just as deadly as the AMX-50 and Lorraine when it flanks or ambushes unsuspecting enemies
  • Good overall frontal armor, the upper turret and upper plate are basically immune to all conventional rounds
  • The strong upper turret coupled with the 8 degrees of gun depression makes this tank great at hull-down fighting and cresting ridge lines
  • Quick and maneuverable for a heavy tank
  • 5-man crew makes this tank highly survivable
  • Can effectively brawl and snipe when necessary


  • Absolutely huge tank, is longer, wider, and taller than the Tiger II - very hard to find proper concealment
  • The neck of the turret is weakly armoured, a prime weak spot that's hard to effectively hide
  • The lower plate is as weak as British lower plates, any APHE shell that enters here will likely knock out the whole crew
  • Will face a lot of enemies that fire APDS and HEAT, the upper turret and upper plate just can't absorb those kind of shells
  • Terrible side armour, side-scraping or angling the tank is extremely hazardous
  • Is much slower than the Lorraine and AMX-50
  • Mediocre elevation angles thanks to the inherent nature of oscillating turrets


At the end of WW2, the French army realized that they needed a new modern heavy tank. The SOMUA Company competed with AMX to design a new heavy tank for France, and they were given the order to build a prototype in 1946. The hull of the tank was based off the German Tiger II, and the tank used an oscillating turret armed with an auto loading 100mm gun. Because the two companies were forced to make a new design with the same requirements, the Somua SM design looked similar to the AMX 50, and both tanks had equipped the 100mm gun. The prototype was delivered in October of 1951 but was still lacking an engine and some other parts. Due to delays, the prototype was not tested until 1953, but it was already too late. The SOMUA’s design was rejected in favor of the AMX 50.
