As of 0.6.0 release,a new commander skill has questioned a lot of the new players who just get his commander ready for the 4th tier skills:"When to use IFHE and when to not?"

Here is a guide for you to not accidentally choose the wrong perks for your lovely commanders :)


In Wows,a HE shell can penetrate armor regardless the angle, and its penetration value is about 1/6 of its gun caliber size.

So for example, a Yamato's HE shell can penetrate armor of

460mm/6

=76.67mm thick

Also,there is a specific value of bow armor thickness in each Tier,regard which nation the ship is.

(There is actually some exception.........like the Flint and the Atlanta)

Here is the full list of bow armor thickness of ships following this rule:

Tier 1-2  All ships

6mm (Do you expect them to have any armor protection?Lol)
  Battleship Cruisers

Destroyers

Carriers
Tier 3 16mm 6mm 6mm Nil
Tier 4-5 19mm 10mm(Kirov/Furutaka:13mm) 10mm 13mm
Tier 6-7 25mm

16mm

(British Cruisers /Atlanta class /Perth:13mm)

16mm

T6:16mm

T7:19mm

Tier 8-10 32mm

25mm

(British Cruisers:13mm)

(Baltimore/Des moines:27mm)

(Kutuzov:26mm)

19mm 21mm

 

As here,someone may ask "Why bow armor?" In order get penetration damage,you will need to shoot HE shells into the thinnest armor (which is usually the bow area)


So,its time for calculation of minimum gun caliber to penetrate the bow armor with IFHE :

The calculation is simple (Bow armor/1.3[effectiveness of IFHE]*6),but I will do this anyway:

  Battleships Cruisers Destroyers Carriers
Tier 1-2

Nil

(well I am not considering Mikasa,since you can't use APHE for Tier 2 if you aren't seal clubbing for real..........)

6mm/1.3*6

=27.69mm(Ignored)

6mm/1.3*6

=27.69mm(Ignored)

Nil

(any Carrier?no)

Tier 3

16mm/1.3*6

=73.84mm(Ignored)

10mm/1.3*6

=46.15mm(Ignored)

 

6mm/1.3*6

=27.69mm(Ignored)

 

Tier 4-5

19mm/1.3*6

=87mm

10mm/1.3*6

=46.15mm(Ignored)

Kirov/Furutaka:

13mm/1.3*6

=60mm(Ignored)

10mm/1.3*6

=46.15mm(Ignored)

13mm/1.3*6
=60mm(Ignored)
Tier 6-7

25mm/1.3*6

=115.38mm

16mm/1.3*6

=73.84mm(Ignored)

British Cruisers/Atlanta class:

13mm/1.3*6

=60mm(Ignored))

16mm/1.3*6

=73.84mm(Ignored)

T6:

16mm/1.3*6

=73.84mm(Ignored)

T7:

19mm/1.3*6

=87mm

Tier 8-10

32mm/1.3*6

=147.69mm

25mm/1.3*6

=115.38mm

Kutuzov:

26mm/1.3*6

=120.00mm

Baltimore/Des Moines;

27mm/1.3*6

=124.61mm

British Cruisers:

16mm/1.3*6

=73mm(Ignored))

19mm/1.3*6

=87mm

21mm/1.3*6

=96.92mm

(The value under 76.2mm will be ignored,as the smallest sub-gun in game is 76.2mm)

In case you are lazy to do analysis,here is the list of ships that can't face their top tier BB opponent because its gun caliber is too small/No HE shell

All T2-T4 DD(except for <content removed> DD)

T-22

T6-T10 DD(except for German T6/T8 's 150mm gun)

Atlanta/Flint

All british cruisers(except belfast)


But there is another story,there are some guns that are too big to be effective with IFHE(like yamato's one)

The calculation as follow (Bow Armor*6):

  Battleships Cruisers Destroyers Carriers
Tier 1-2 Nil

6mm*6

=36mm

6mm*6

=36mm

Nil
Tier 3

16mm*6

=96mm

6mm*6

=36mm

6mm*6

=36mm

Nil
Tier 4-5

19mm*6

=114mm

10mm*6

=60mm

Kirov/Furutaka:

13mm*6

=78mm

10mm*6

=60mm

13mm*6
=78mm
Tier 6-7

25mm*6

=150mm

 

(British Cruisers/Atlanta class

13mm*6

=78mm)

16mm*6

=96mm

T6:

16mm*6

=96mm

T7:

19mm*6

=114mm

Tier 8-10

32mm*6

=192mm

25mm*6

=150mm

Kutuzov:

26mm*6

=156mm

Baltimore/Des Moines:

27mm*6

=162mm

(British Cruisers

16mm*6

=96mm)

19mm*6

=114mm

21mm*6

=126mm

This is the max gun caliber that individual ships's Bow armor can stand


Compared the two table,we can find a list that in which tier is IFHE usable (when facing top tier BB opponents)

  Battleship Cruisers Destroyers Carriers
Tier 1-2   Nil Nil Nil
Tier 3 Nassau,Kawachi's sub gun Nil Any gun excet Wakatake's 120mm gun Nil
Tier 4-5 Any 150mm sub-gun Kuma's 14cm gun Isokaze's gun Nil
Tier 6-7 Any 150mm sub-gun Russian CL/Nurnberg/Cleveland Nil Nil
Tier 8-10 Any 150mm sub-gun Russian CL Nil Nil
