[Client Values; Actual values in
Specifically, the mismatch in crew values caused by commander's 10% crew skill bonus. Outside of a crew of 1 commander only, 100% crew is a fiction. The client values, given for 100% crew, will normally be taken into battle with 110% crew skill members aside from specific functions, causing their actual performance to deviate from the expected client value. These differences are taken into account in tooltip boxes.

The Bat.-Châtillon 155 55 is a French tier 9 self-propelled gun.

A 155-mm SPG design project developed in 1955. The vehicle was intended to be manufactured on the chassis of the U.S. M47 medium tank, which was exported to France. However, the chassis of the French medium tank Batignolles-Châtillon 25 t was preferred over other variants. The initial version existed only in blueprints.

The Bat.-Châtillon 155 55 leads to the Bat.-Châtillon 155 58.

Player Opinion

Pros and Cons

Pros:


  • Gun range: stock: 1350 m, top: 1400 m
  • Mobility is very good, comparable to a medium tank
  • Rotating turret and relatively high accuracy
  • Fast reload speed, high firerate
  • Painless stock grind; top gun only improves aiming time by 0.5 seconds


Cons:


  • No gun depression making 'TD Mode' hard
  • Low alpha damage per shot. Avoid shooting heavily armored targets. Even frontal his on a Foch may do only ~200 damage
  • Needs a Radio Operator unlike its predecessor and successor, breaking Brothers in Arms
  • Low shell arc on its guns
  • Useless 185mm pen HEAT round


Performance

The Bat Chatillon 155 55 is a very different artillery piece than any of the other tier 9's. It features a 155mm gun that has the lowest-in-tier 1250 alpha damage, but the best accuracy and reload of any artillery piece in its tier. Similar to the Lorraine 155 51, it deals its damage over time by putting large numbers of rounds downrange. However, due to its low alpha damage, its damage can vary greatly, as many of the super-heavy tanks in the game can shrug off its hits for little to no damage. The gun, other than the damage, is a straight up upgrade to the tier 8 Lorraine 155 51, with better reload and accuracy. It also gains a full 360 degree turret, which allows you to switch targets more easily. The Bat Chatillon 155 55 is interesting in TD mode due to its high mobility and full turret, allowing it to surprise enemies from unexpected locations. However, it is hindered due to its low alpha, meaning that the target will often survive your one shot, and nonexistent gun depression, which can make it hard to hit things.


Early Research

  • The SCR 528F Radio carries over from the Lorraine 155 mle. 51. Mount it immediately.
  • Research the Batignolles-Châtillon 155 mle. 56 suspension first. It gives huge boost to mobility.
  • Research the Canon de 155 mm Gun.
  • If you want more mobility, research the Continental AV-1790-7B Engine.
  • Go from there.

Historical Info

Batignolles Chatillon 155mm
Following Lorraine’s project of the self propelled howitzer, Batignolles Chatillon started the work on the self propelled artillery vehicle with a fully rotatable turret. Main feature was to be drum based automatic loader system installed in the turret. In late 1958 all development was canceled and project was abandoned with only a one prototype built.
