(A redeveloped thread because people keeps thinking I'm talking about Armor and Survivabilty and not about Overmatch and Penetration and also cant stand a Yamato being compared to anything whatsoever because Hotel-Chan is sacred ground and worshiped daily)

 

 

OVERMATCH MECHANICS

 

14.3x

Remember this magic number during this thread.

 

 

For those who play World of Tanks, you would know that Overmatch Mechanics exist. Overmatch in WoT happens when this condition is fulfilled:

Shell Calibre > 3x Thickness of Enemy Armor

For example, a Jagdtiger AP Shell will always penetrate a AMX 13 90's front hull at any angle without exceptions because a 128mm shell is more than 3x the thickness of a 40mm front armor plate.

 

 

In World of Warships, Overmatch mechanics exist as well, Overmatch in WoWS occurs when this condition is fulfilled.

Shell Calibre > 14.3x Thickness of Enemy Armor

For example Yamato's 460mm shells will always penetrate a bow armor of a Iowa because 460mm > 14.3(32mm) = 457.6mm

However you dont really notice Overmatch Penetrations because of OverPenetrations, usually a shell that size compared to an armor that thin would OverPen and deal 10% damage i.e. DDs and CLs.

With the above in mind, lets take a tier by tier analysis on what ships DO benefit from Overmatching?

I this I will only cover Battleships because they do most of the overmatching.

 

The importance of understanding why Overmatch matters is because if you point your bow as a Battleship towards another Battleship in an attempt to heavily angle your front bow armor such that the enemy BB shells will ricochet off, it wont happen because Overmatch Trumps Angles

 

Tier 2:

 Mikasa - Caliber : 305 - Overmaches up to 21mm

Armor scheme

Spoiler

Mikasa's can overmatch her own top half of her bow and stern armor. She also can overmatch the top half the bow and stern of the Tier 3 BBs. (She doesn't see tier 4s.)

 

 

Tier 3:

South Carolina - Caliber : 305 - Overmaches up to 21mm

Armor scheme

Spoiler
 

Kawachi - Caliber : 305 - Overmaches up to 21mm

Armor scheme

Both the SC and Kawachi can overmatch the top half of the their own, the Mikasa's, Myogi and Kongo's bow and stern armor.

The SC and Kawachi can fully overmatch the front of the Wyoming, Arkansas and New York's.

 

 

Tier 4:

Wyoming / Arkansas - Caliber : 305 - Overmaches up to 21mm

Armor scheme

Imperator Nikolai - Caliber : 305 - Overmaches up to 21mm

Armor scheme

 24ms75l.png

 

Myogi - Caliber : 356 - Overmaches up to 24.9mm

Armor scheme

 2nv78rn.png

All the tier 4 BBs can overmatch the top half of the all tier 3, 4 and 5 BBs except the Wyoming and New York, where they gets fully overmatched frontally.

 

 

Tier 5:

 New York - Caliber : 356 - Overmaches up to 24.9mm

Armor scheme

Spoiler

 

Kongo - Caliber : 356 - Overmaches up to 24.9mm

Armor scheme

13z1jl1.png

Kongo's and New York's can only overmatch the top half of the all tier 3, 4 and 5 BBs except the Wyoming and New York, where they gets fully overmatched frontally.

However, unlike their lower tier counterparts, they can not overmatch tier 6 BBs.

 

 

Tier 6:

 New Mexico - Caliber : 356 - Overmaches up to 24.9mm

Armor scheme

Spoiler

 

Fuso - Caliber : 356 - Overmaches up to 24.9mm

Armor scheme

Warspite - Caliber : 381 - Overmaches up to 26.6mm

Armor scheme

 2805edj.png

This is an interesting part. The Tier 6 BBs can overmatch the top half of the all tier 4 and 5 BBs except the Wyoming and New York, where they gets fully overmatched frontally.

Tier 6 BBs can not overmatch each other with the exception of one BB.

The Warspite.

The Warspite is capable of overmatching the top half of the Fuso's armor and can overmatch the whole bow of the New Mexico.

She is also capable of overmatching both Tier 7 BBs bow armor (25mm) as well. Warspite can not overmatch Tier 8 BBs bow armor (32mm)

 

 

Tier 7:

Colorado - Caliber : 406 - Overmaches up to 28.3mm

Armor scheme

Spoiler

 

Nagato - Caliber : 410 - Overmaches up to 28.6mm

Armor scheme

 2llhlhu.png

Both Tier 7 BBs are capable of overmatching themselves but are unable to overmatch any Tier 8 BB.

That being said, they are both capable of fully overmatching Warspite, New Mexico, and New York.

Kongo's and Fuso's can be overmatched if the top half of the bow armor is hit.

 

 

Tier 8:

Tirpitz / Bismarck - Caliber : 380 - Overmaches up to 26.5mm

Armor scheme

Spoiler

 

North Carolina - Caliber : 406 - Overmaches up to 28.3mm

Armor scheme

 5yi64m.png

 

Amagi - Caliber : 410 - Overmaches up to 28.6mm

Armor scheme

 250sa6x.png

Tier 8 BBs are capable of fully overmatching the Colorado and New Mexico.

They are capable of overmatching the top half of Fuso.

However, they are NOT capable of overmatching any tier 8, 9 or 10 BB.

 

 

Tier 9:

Iowa - Caliber : 406 - Overmaches up to 28.3mm

Armor scheme

Spoiler

 

Izumo - Caliber : 410 - Overmaches up to 28.6mm

Armor scheme

 25g3ukg.png

Tier 9 BBs are capable of fully overmatching the Colorado

However, they are NOT capable of overmatching any tier 8, 9 or 10 BB.

 

 

Tier 10:

Montana - Caliber : 406 - Overmaches up to 28.3mm

Armor scheme

Spoiler

 

Yamato - Caliber : 460 - Overmaches up to 32.16mm

Armor scheme

9awzg8.png

This is where we see why the Yamato is so much better than the Montana.

This is why Yamato outperforms the Montana to such a great degree.

This is the explanation on why the Yamato is always able to penetrate and citadel whilst the Montana cant.

 

Its because the Yamato can overmatch up to 32.16mm of armor. Tier 8, 9 and 10 BBs have bow and deck armor of 32mm. This is why at long range, the Yamato is always able to citadel you because it ignores the 32mm bow armored deck. (On Montana its 29mm on the middle)

 

tl;dr: Overmatch greatly benefits these two ships, the Yamato (which can overmatch up to 32.1mm armor - the common bow, stern and deck armor of Tier 8, 9 and 10 BBs) AND

The Warspite (which can overmatch up to 26.6mm armor - the common bow, stern and deck armor of Tier 7, 6, 5 and Tier 4 BBs [which has 19mm])

PENETRATION MECHANICS

(WIP)

 

A good read about dealing damage in World of Warships found here

Formula

Posted Image

 

A as the stated Krupp-value

v as the velocity in m/s,

d as the caliber in decimetres,

m as the mass in KG

result (Sb) is the penetration in decimetres.

Too.....

Much......

Maths..........

 

That's why I trust in Torpedoes, can't bounce ! LOL.......

 

Yet torpedoes have their own separate math in dealing damage.

So the takeaway from this boils down to "Too much angling is bad".

 

That, broadly speaking, you really do want to take the hits if possible on your belt armour, and so angle to 

1) maximise the chance of a hit on the belt

2) while making the angle of impact on the belt as great as possible

 

Of course these 2 objectives contradict, but that is OK, because if was easy anyone could do it

@simo 

nope. angling is good.

 

PS for all of you :

overmatch cant beat auto bounce

even 460mm cant beat auto bounce

 

In the first post - Overmatching trumps the autobounce. it means that the shell fired has sufficient velocity to penetrate regardless of the angle it hit at.

 

However, angling is still good, but the amount you angle can be determined by the findings that DeathSkyz has posted. Against a ship capable of overmatching you - just go as close to head on to them to minimize target profile, making dispersion work for you. Otherwise, if it can't overmatch you, that means you can swing out a bit more, making it easier to unmask the rear batteries.

I get the overmatching I think.  Still confused, when will you overmatch, without over-penning?

 

If you overmatch but your round still has enough penetration to penetrate the citadel armor, you get a citadel. 100% damage.

If you overmatch but your round doesnt have the penatration power to pen the citadel armor, you get a regular penetration. 33% damage.

If you overmatch but your round goes thru and thru the enemy ship (i,e, fired at side of bow), overpenetration occurs and you get 10% damage.
