The '''{{specs|name}}''' (DE 75 mm Self-Propelled Gun SAu 40) is a Rank {{specs|rank}} French tank destroyer {{Battle-rating|1}}. It was introduced in [[Update 1.75 "La Résistance"]]. It distinguish itself by its very tall cupola and thick gun barrel. This tank is equipped with APHE rounds, a rare feature in the French tech tree.

The '''{{Specs|name}}''' (shortened as '''{{Specs|pseudonym}}''') is a gift rank {{Specs|rank}} French tank destroyer {{Battle-rating|1}}. It was introduced in [[Update 1.77 "Advancing Storm"]] during the [[wt:en/news/5453-special-chronicles-of-world-war-ii-in-war-thunder-en|2018 WW2 Chronicles]].
 
 
As it was developped from the French [[S.35]], this tank shares many of its characteristics such as ~40 mm cast hull bolted onto the chassis, which is barely a widened version of its original. The track system is mostly the same as on the [[S.35]], with 25 mm plates covering the roller wheels. As for the hull, its two 8 mm ''grilles'' over the engine compartment and doors on the side reinforces the impression that it's just a widened [[S.35]] hull.
 
 
 
As this tank is based off the [[S.35]], it shares many of its attributes when it comes to armour. A slight angle can defeat most shots this tank will take at this BR, this is useful to know when getting into position: from a distance and not showing neither side nor front to the enemy, you should be safe. As for frontal armour, its 40 mm overall thickness is not strong enough to withstand anything bigger than AA fire. But, a thing to consider with this weird pattern is its "bouncy" behaviour,  principally around the gun mantlet: complex angles may just bounce some shots, making them loose some energy before hitting the main armour, this feature is peculiarly distinctive at gun's height.
 
 
 
The main weakness of this tank is its ''very tall'' commander's cupola, which makes it quite easy to spot and destroy, as it is thinner than the main armour. Any APHE penetrating this area will kill the tank's commander, thus disabling its only MG and some shrapnels may even damage or kill the driver, disabling this tank for good. A way to avoid getting spotted too easily is buying camouflage for the front cupola area, making it look more like a bush popping out a hill than a tank's turret. Try to hide the tank's lower hull part as it is only 35 mm thick.
 
 
 
While being mounted on a widened [[S.35]] hull, this heavier tank has about 70 HP less than its predecessor, making it quite slow and unwieldy. In order to fulfill the task of getting into position, one should choose its route wisely and avoid risky spots as this tank's ''awful'' reverse speed and hull turning rate makes it quite bad at hasty retreats. Mobility with the Somua 40 is an issue. It is arguably what makes this tank hard to master as it does not allow for good map placement.
 
 
 
As any casemate SPG, this tank's main feature is its main gun...kind of. With average penetration rates for this BR with a maximum of 73 mm at point-blank ranges (comparably, the Russian [[SU-76M]] penetrates 80 mm with its basic APHE shell and up to 135 mm with APCR shots). While being one of the rare French tank shooting APHE shells, increasing its one-shot potential, this round noticeably fails to explode when flanking enemies as this round takes 25 mm of steel to detonate. Another concern being its slow horizontal traverse, which makes it hard to react to fast-paced situations. This gun placement makes this tank quite vulnerable: being low, it exposes the SOMUA 40 to enemy fire when popping up a hill.
 
 
 
As for the turreted MAC 31 MG, it does not helps at anything more than taking down truck-mounted guns. This turret is slow, which negates the possibility of chasing planes with it. It also has poor rate of fire and is low calibre, so even if you manage to hit a plane, it will not do much to it.

The Lorraine 155 Mle.50 has very little armour (although some are sloped enough to deflect certain low-rank rounds), and can generally be penetrated by most guns of its rank. Even worse, however, the 'casemate' (if it can even be called that) has very little armour, and in some places can be shot through with machine guns. The machine-gunner (operating the 151) is completely open to the elements. Generally, you want to rely on good map placement and mobility, rather than armour.

The Somua 40 behaves as a classical casemate SPG as it should provide its teammates with superior firepower from medium to far distance, behind the frontlines where it will be harder to flank. As this is its purposed role, this tank has some issues accomplishing it. The first being its relatively low penetration and shell velocity, which makes long range engagements (>750 m)a bit hard to manage. The second being bad mobility, which complicates the task of positioning.
+
The best method of using the large-calibre weapon on the Loraine is to exploit the high-explosive power against thin-armour on the enemy. Like other large calibre HE tanks, shooting below an enemy vehicle will penetrate its belly armor. This is an effective, albeit difficult way to engage tanks whose armor is greater than what your HE shell can penetrate.
 +
 
 +
Some targets to keep in mind of, and their weak points:
  
Act as a classical SPG while keeping in mind your slow pace. There is nothing very much interesting nor special you can do with this tank.
+
* Tiger I - While seemingly a hard enemy to face, the Tiger is easily dispatched with a side shot. A hit to the roadwheels will penetrate the tank, with the shell fragments going through the thin armor on the underside of the tank's sponson. This is also possible to do to Tiger IIs, but usually results in much less damage done.
 +
* Tiger II P, Panthers D and A - a hit to the bottom of the curved turret face of these tanks will cause the HE shell to pen the roof of the vehicle. This can also be done on tanks with flat turret fronts ( Tiger I, Tiger II H, Panthers G and F) by aiming for the lower half of the turret, but is not as reliable.

The SAu 40 self-propelled gun was developed by the SOMUA company between 1935 and 1937 as part of the same order the French cavalry placed for the S35 tank.  
+
Prototypes of the Lorraine 155 Mle.50 passed trials in 1950, but never reached production.
  
The two tanks combined were intended to equip light mechanized divisions of the French army and support the larger “battle tanks” (chars de bataille). The vehicle inherited the S35’s characteristic chassis with a redesigned front section of the hull to accommodate the 75mm APX cannon. In addition, the rotating turret on top of the fighting compartment was redesigned to a commander’s cupola and moved to the side of the vehicle, but the turret’s 47mm cannon was replaced with a single 7.5mm machine gun.
+

<!-- ''Excellent additions to the article would be video guides, screenshots from the game, and photos.'' -->
The body of the SAu 40 was ready by 1937, but it couldn’t be immediately completed. Because the cannon was not yet ready to be installed on the chassis, SOMUA engineers had to wait nearly 2 years before the cannon was finally made available. It wasn’t until 1939 that the fully assembled prototype was completed, and orders for mass production were received in October of the same year.  
 
  
Whether or not any additional vehicles other than the prototype were built or if the vehicle took part in active fighting is unknown.

Description

GarageImage Lorraine 155 Mle.50.jpg


The Lorraine automoteur de 155 mm modèle 1950 (shortened as Lorraine 155 Mle.50) is a gift rank III French tank destroyer with a battle rating of 4.3 (AB/RB/SB). It was introduced in Update 1.77 "Advancing Storm" during the 2018 WW2 Chronicles.

General info

Survivability and armour

The Lorraine 155 Mle.50 has very little armour (although some are sloped enough to deflect certain low-rank rounds), and can generally be penetrated by most guns of its rank. Even worse, however, the 'casemate' (if it can even be called that) has very little armour, and in some places can be shot through with machine guns. The machine-gunner (operating the 151) is completely open to the elements. Generally, you want to rely on good map placement and mobility, rather than armour.

Armour type:

  • Rolled homogeneous armour
  • Structural steel
Armour Front (Slope angle) Sides Rear Roof
Hull 16 mm (70°) Front glacis
16 mm (2-73°) Transmission housing
16 mm 10 mm (0-42°) 10 mm
Superstructure 16 mm (21°) Front
10 mm Gun shield
16 mm (30°) Right side
16 mm (21-48°) Left side
10 mm 10 mm
Armour Sides Roof
Cupola 10 mm N/A

Notes:

  • Suspension wheels are 10 mm thick while tracks, sprocket wheels, torsion bars, and return rollers are 20 mm thick.
  • Belly armour is 10 mm thick.
  • Gun breech is 300mm thick, while the barrel itself is 25mm.
  • Gun carriage around the gun is 20mm thick, while the gun mount/traverse device is 40mm thick.

Usage in battles

The best method of using the large-calibre weapon on the Loraine is to exploit the high-explosive power against thin-armour on the enemy. Like other large calibre HE tanks, shooting below an enemy vehicle will penetrate its belly armor. This is an effective, albeit difficult way to engage tanks whose armor is greater than what your HE shell can penetrate.

Some targets to keep in mind of, and their weak points:

  • Tiger I - While seemingly a hard enemy to face, the Tiger is easily dispatched with a side shot. A hit to the roadwheels will penetrate the tank, with the shell fragments going through the thin armor on the underside of the tank's sponson. This is also possible to do to Tiger IIs, but usually results in much less damage done.
  • Tiger II P, Panthers D and A - a hit to the bottom of the curved turret face of these tanks will cause the HE shell to pen the roof of the vehicle. This can also be done on tanks with flat turret fronts ( Tiger I, Tiger II H, Panthers G and F) by aiming for the lower half of the turret, but is not as reliable.

Pros and cons

Pros:

  • Powerful 155mm gun with a HE shell on-par with the KV-2's gun
  • Pintle-mounted 20mm cannon that is deadly to lightly-armoured vehicles and aircraft
  • Decent mobility
  • Good reverse speed

Cons:

  • Thin armor with an open casemate, allows even rifle-calibre rounds to affect the crew
  • Despite thin armor, it's thick enough to trigger most fuses in APHE shells
  • Large profile
  • Long reload time; increases if the loader is taken out
  • If the machine-gunner is knocked out, so is the ability to use the 20mm cannon
  • No AP shells, only HE shells
  • Bad gun depression of 5°

History

Prototypes of the Lorraine 155 Mle.50 passed trials in 1950, but never reached production.
