The '''{{Specs|name}}''' is a gift rank {{Specs|rank}} Soviet heavy tank {{Battle-rating}}. It was introduced in [[Update 1.67 "Assault"]]. This is one of the most dreaded tanks of its BR spread since it features a good cannon and awesome mobility packed inside a heavily sloped thick armour that most APHE shells cannot penetrate. Use this tank in any role and situation, it will surely find its place on the battlefield. Having very good mobility and a respectable reverse speed allows the IS-6 to plow through sticky situations that many other tanks would struggle with.
+
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]].

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.
If necessary use a visual template to indicate the most secure and weak zones of the armour.-->
 
100 mm sloped at more or less 60­° on all sides provide this vehicle with a reputation to be a ''ricochet master''. Firing on the hull from almost any angle will only result in a glancing shot. The only weak spot being the lower sides of the hull and turret sides and rear, the only way to reliably penetrate it is to get a shot from the side. An attentive player that never shows the sides is an invincible opponent. However, be aware of the frontal armour, as the extremely angled turret armour encasing the cannon breech can create a shot trap and ricochet the shell into the driver's area. This will likely result in your ammo exploding. Be wary when facing any opponent.

*Suspension wheels are 20 mm thick while tracks are 30 mm thick. Torsion bar connectors by the wheels are 60 mm thick.
+
* Suspension wheels are 10 mm thick while tracks, sprocket wheels, torsion bars, and return rollers are 20 mm thick.
*Spaced armour plates are placed on the sides, giving an additional 10 mm of side armour.
+
* Belly armour is 10 mm thick.
 
+
* Gun breech is 300mm thick, while the barrel itself is 25mm.
From the front, only high-end rounds (HEAT-FS, HESH, APFSDS) can penetrate the IS-6. Otherwise, flank it since its lower side armour is unangled behind the tracks. In a close to medium range fight, if the IS-6 is static and facing you, try to shoot its right side turret cupola, a penetrating APHE shell may knock out the commander and gunner, disabling the tank (some large calibre rounds can even knock out the loader and/or driver, resulting in an instant elimination). This strategy is unapplicable with rounds that don't have HE filler.
+
* Gun carriage around the gun is 20mm thick, while the gun mount/traverse device is 40mm thick.
 
 
Another weak spot is the left side of the mantlet which has the optics in it. This part of the armour is thin enough that most shells at the BR can penetrate it, and in doing do, incapacitate the commander and gunner and destroy the cannon breach. If you are lucky and the IS-6 has ammo in the back of its turret, there is a chance to detonate it as well for an instant elimination.
 
 
 
If you happen to flank an IS-6, take the time to aim since half of its side is covered by its dreaded armour. A missed shot will alert the IS-6 player, withdrawing with its fast speed from sight before another shot could be landed. Turret sides and back can ricochet rounds as well, so keep the hull as a priority target.
 
 
 
If encountering this foe from its back, keep in mind to aim for the middle of the engine deck since plates on both sides are as though as their frontal counterparts. If confident, go for it and aim at the turret back.
 
 
 
Any round penetrating the crew compartement leads to an ammo rack detonation most of the time since this tank's interior is filled with ammo all over the place.

If used well, the {{PAGENAME}} can get into position as fast as a T-54. It is certainly one of the fastest late IS-series tanks. It reaches 44.3 km/h (27.5 mph), the top speed in RB, with ease and has a reverse speed of -16.1 km/h (10 mph).

The IS-6 features an upgraded version of the [[D-25T (122 mm)|D-25T]] gun found on other IS series variants, the D-30T. Though identical ballistically, it provides a much faster reload, with the IS-6 having a default reload rate only 0.5 seconds longer than the [[T-10M]]. The IS-6 uses the same ammo load as the [[IS-2]] with the best shell being the BR-471B, which means the tank will have trouble against some heavies it may encounter from lacking penetration. In addition, the IS-6 does not have access to the BR-471D, which is usable on the IS-3, also at 7.3 rating.

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.

The IS-6 is best used as a breakthrough vehicle, supporting teammates at the front lines, use your good reverse speed to get out of sticky situations and only show your front to the enemy. Avoid vehicles with HESH, HEAT-FS and APDS (Leopards and Centurions are good examples).

Prototypes of the Lorraine 155 Mle.50 passed trials in 1950, but never reached production.
  
The Chelyabinsk Kirov Plant Work (ChKZ) began drafting the designs of a new heavy tank on 02 May 1944<ref name="TankArchivesElectric" /> with an electrotransmission, a drive system that was used on the German [[Ferdinand|Ferdinand/Elefant]]. The plant was officially ordered to begin work on June 08<ref name="KinnearT10" /> for two versions of the heavy tank, with emphasis of having significant advantages over the current [[IS-2 (1944)|IS-2 heavy tank]]. The heavy tank was designated as the '''IS-6''' and the two versions were the ''Object 252'' with a mechanical transmission and the ''Object 253'' with a electric transmission.<ref name="TankArchivesLaunch" /> Both prototypes were produced in the Fall of 1944 and were sent to be tested at the NIIBT testing grounds at Kubinka.

The two prototypes differed in more ways than just the transmission. Object 252 used the mechanical transmission from the [[IS-3]], with large road wheels and no track rollers for its torsion bar suspension.<ref name="BoldyrevTank" /> Object 253 used an electric transmission with a suspension that looked similarly to previous IS iterations with smaller road wheels and track rollers. The IS-6 prototypes failed to stay under the weight of the IS-2, being around 51.5 tons.<ref name="TankArchives257" /> The 122 mm gun arming the IS-6 was the D-30, compared to the D-25T on the predecessors. The D-30 implemented features such as the D-25's monobloc design, the 100 mm D-10's breech and gas block, a two-spring balancing mechanism, a lengthened D-25 mount, and a fume extractor. This gun was installed onto the IS-6 prototypes in December 1944.<ref name="TankArchivesD-30" />

The IS-6 prototypes were tested alongside the ''Object 701'' (the prototype of the [[IS-4M|IS-4]]).<ref name="TankArchives257" /> The two IS-6 prototypes proved disappointing, with the Object 253's electric transmission being too complex, expensive, and unreliable.<ref name="KinnearT10" /> The Object 252's mechanical transmission also suffered from reliability issues. Suspension problems also impacted the IS-6, with its speed dropping below the heavier Object 701. It was hoped that the electric transmission would help make the tank more maneuverable, but the heavy weight prohibited any vast improvements.<ref name="BoldyrevTank" /> Overall, the IS-6 armour was deemed to not provide any improvements over existing designs, having only comparable armour, firepower, and mobility to the IS-2 and IS-3. In 1945, all work on the IS-6 ceased as work continued on the Object 701.<ref name="TankArchives257" />

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.
