I just want to be on the red team one time. Whenever I play this game, the red team always wins!

This game is a hell of a lot more complex than I thought

Saw in Twitter how hard you worked on this. Means a lot that you will do this for your fans.

This is probably the single best captains academy video to date, hands down. Great job.

Seriously, thank you for this video, I've been playing this game since CBT and all of this stuff still confuses the hell out of me

Thank you so much for this!!! Now I can really learn how to use my ships. Wish WoWs had an armor view system like Warthunder. They gib all the info and you can actually simulate the shell hitting the armor at various angles. Thank God thee are people out there like you and the 2 you mentioned in your video to present us with the data. Hats off to fnord_disc for this beautiful data set. I am not used to people making such professional ones.

Your series has been incredibly informative - thank you! I just wanted to add that at 17:15 The relationship of effective armor thickness (T) versus incident angle of shell (A) goes like T=t/cosine(A), A between 0 & 60. (t=actual ship armor thickness) 27:44 The graphic shows the shell refracting into the ship side, i.e., turning into the denser medium from air to metal (I never considered that a shell would do that, but it makes sense since other thinks like light and mechanical objects like sound and rolling object obey Snell's law as well).

Here I am on ps4, multiple years after discovering your great channel, coming back to once again learn how citadels work..!

Very useful video, thank you Chase. I can add a tiny bit of information from my personal experience: a fast way to estimate the angle of a far target in artillery view (besides looking at the minimap for some rough idea). Look at the distance between the smoke stack(s) and turrets, more specific between the furthest foreword and furthest aft turrets and the foreword and aft smoke stacks if the ship has more than one of these. If the smoke stack appears to be roughly at the same distance from the extreme turrets your target is more or less broadside and you can go for the citadel, otherwise aim higher or switch to HE. Applicable only for cruisers and battleships, of course.

These captain academy videos are very technical, informational and helpful. Thank you for the hard work!

So, basically, after spending half an hour watching this, I got a LOT of technical knowledge I didn't have but, as far as the battlefield goes, my take away is, shoot at the enemy inside 7km, at the waterline as close to 90 degrees to the side of the target as possible. Sweet!

Coming back for a refresher. That elusive citadel.

Awesome and very informative video Chase! I now understand better why the bloody hell I'm getting a lot of overpens and some bounces.

Nice. One thing I'd like to point out though is that you talk about angles as a definite constant. The thing is though that there are two ways you're mentioning angle. In one you define straight-on-flat-surface as 90° and in the other you define it as 0°. When you show the angle-thing at 18:28 this becomes most obvious as the angle-to-armor values you mentioned before would imply the armor becoming stronger the more straight-on you fire. The 60° auto-bounce in that example would be 30°, 30° from the ships length axis, but 60° from straight-on.

I have been using AP in my Gearing against Smolis very effectively (I love killing those fkn things). After watching this I will use it a lot more. TY!

Great video Chase! Can't wait to study all the intimacies of my opponents citadel.

I remember having a BB gun autobounce off me once as a DD when I was getting in. I was like "Wait they hit me where's the damage I take?"

The test of auto bouncing should also note that your forward guns are shooting from a different angle than your rear guns. It's a small difference, especially as distance increases, but it becomes more significant at these close ranges.

.1 x10^4 lol Why not just say “kilometers” ? Awesome table, little hard to understand at first until you see 10^4

Best wows-theorycraft vid this far!

wow i just downloaded the game and discovered your channel... very good info and editing and a TON of videos... very nice, appreciate your hard work! ez supped

the first professor of WoWs to post in yt :D i know there r plenty more in forum, website, but meh tldr (sorry) & thnx for the video

Thank you chase! Your videos are always entertaining and helpful!

Very well done. I'm an not sure I can remember all of this for every ship especially in battle. Good to know though. Thanks, Puddahead

Hey Chase, great work. You forgot to mention the USN 8 inch cruiser shells behave slightly different in the auto-bounce mechanic (bouncing starts at 60 degrees and auto-bounces at 67.5 degrees).

Keep in minds that there is still a plate of 127 -140 mm of middle deck armor that doesn't show up in the armor viewer but does in the data mine. That's part of the reason it has good protection from AP bombs.

Great video 👍

Excellent, excellent work. Very well researched, detailed and explained!

Love to see the T10 BBs, compared and why WG needs to help montana when it comes to the over match mechanic.

you being a young guy id have thought youd have moved on with other games (because this video is 6 years old). you however have not, your dedication to this game is impressive and a quality not found in many young people as i have seen, good on you

Amazing video. Cherry on the top. Thanks and congrats!

I had a general idea of how the pen and overmatch system worked but this helped a lot, thanks. Although i cant play right now cause my cooling fan decided to be not cool anymore and my computer just overheats lol. But, hopefully ill be able to get back to it quickly,

iChase when talking about impact angle it's the angle between between the tangent to the trajectory at the point of impact of a projectile and the plane tangent to the surface of the ground or target at the point of impact. So when a ship is fully broadside the impact angle of your shells is 0 degrees not 90! Otherwise great video

Thank you for taking the time to make these tutorials.. i have learned a lot from them.

Very helpful, when I try to run away from a Khaba in the Yamato =/ JK Really helpful to explain why I get all of over pen in Zao in close range. Thank u chase

Thank you iChase - Great information and presentation!

Awesome. Thanks again for the elaborate descriptions!

the auto ricochet mechanic is the reason why, after i fire i turn my battleship towards the enemy im shooting at. then turn back when im reloaded

Feels like American BB from NC onward as well as CA from Baltimore onward have a higher chance of landing citadels when you shoot a enemy's deck or superstructure instead of the sides because American superheavy shells have high arc and will basically drop on the deck and pen the weaker deck armor.

wow...very good explained chase...helps me very lot...ever wondered why the hell i get no citadell at a North.Ca thank you very much :)

the 90 deg mark should be considered the bow of your ship. 0 degrees is broadside. other than that this is an awesome video and was really helpful.

P.S I remember your Izumo video and this bow-on you mentioned reminds me of a time when I completly wrecked a montana with it.

just a side note- normalization is explained backwards....normalization process increases the penetration angle in favor of...the shell

does WoWS water auto stop shells? or can you aim below the water line at close fire to go through the water and hit citadels below the water.

Great vid Chase. Personally, I think this or a slightly condensed version should be required watching for anyone playing past tier 3. LoL The only thing you didn't cover was loss of pen on AP shots over distance. Do you have numbers for that??

high quality guides, subscribed!

i always thought iowas where easier to citadel than nc, thanks for explaining the reason behind that.

Great Video Chase again! Love your videos!

At 21:10 it's a 50 degree actually, not 40, cuz you are counting from 90 degree angle, not from the bow of the ship if i got it correctly.

And now the playlist for the series needs to be in the video discription as well :D

i think the issue with pensacola is plunging fire from bbs rather than that tiny space above the waterline

I hate to point this out but the north car is one of the easiest ships to cit up close or far away lol. just go in training room and test it. I understand what your trying to point out but I've never had a problem citting a NC at any range and it's known to get cit almost every time it's broadside

Great video Chase! Sadly I cannot use any of the information in it till around Thanksgiving or Christmas. This semester of college is going to be brutal. Sixteen hours of straight Mechanical Engineering classes. Imgunnadie

CHASE CANT WATCH STRAIGHT MY ISP CANT HANDLE THE QUALITY OF THAT MAGNITUDE :P

Nice thanks for making these it really helps a lot.

The penetration mechanics and shell behavior is extremely simplistic combined with the dispersion it's really weird how BB caliber performs. On AP with heavy cruisers you get same problems with strange overpens and not being able to citadel when you should be.

It felt like I just sat thru a Physics class >_< Well that explains why I was able to one shot an Iowa in my Amagi at point blank from about 20deg angle at the waterline, right under the 2nd gun turret. That thing's citadel is so high above the waterline.

wow! didnt kno there was so much in it. v-technical vid. lv the info n thx.

Wish you demonstrated citadels at BB's longest ranges. Most of the fights usually lie in the mid to long range with only a few close quarter fights.

These videos make me realize how bad I am at this game and that I should give up becasue I will never get good.

The first video about penetration i watch on youtube^^

yes, very well explained and not as boring as the last one ;-) Did you considered recording mouse pointer? I dont know if I asked you before.

a minor pet peeve but it's not 'autobounce' unless it's 100% chance. before that it's just "bounce" and "bounce chance"

Very helpful video, thank you!

Great info, Keep them coming.

just have to say like most other here: thank you so much for spending time (a lot probably) researching and teaching us this. The only thing i wonder: I have studied physics and mathematics (too name a few) on university level. And I am a pretty big second WW nerd! I have studied some of these ships historical facts and read myself up on how shells behave in real life. Arcs, velocity, angles, armor, explosives and dynamite types and much more. But does this game take into account all of that real life physics or is it just a game where you cant trust it to follow real life rules of behavior for firing ship cannons? Besides that thank you again for your outstanding research and pedagogical teaching. :) pplease make more of these videos! :) bewst reg from oslo/norway

So angling increases your armour exponentialy, not linearly as you asume, eventho your results tell the opposite

nice lesson Mr.Ichase. however, this lesson is about AP shell. I kinda want to know about HE shell that CA spit out all the time so I can minimize their damage.

great vid ichasegaming

Really useful, nice video :D

Speaking of armour penetration. If you're in a Russian gunboat and shooting at max range against enemy cruisers or battleships, is it worth using AP? I'm thinking that with the high arcs at max range, there'd be a high likelihood the shell would hit the (lightly armoured) deck from above.

Great tutorial. its always good back to basics and learn again what ur doing wrong. lol.

+iChaseGaming there is a mod in Aslain's mod pack that show you an angle that enemy ship is for you. You should check that out. It would really help you :)

So, quick question... The towers, the chimneys, the deck.. are they considered like no armor at all?

Really good video, thanks

This came out at precisely 2:00 o clock I the UK

iChase can you explain overpenetration mechanics in the game as well please since I don't get what the triggers are for it.

So calculating the overmatch is to use the real armor number but not the angled armor number?

I can see in the video you are using the training room mod and would you get banned for it or is it alright to get?

Pepsi is wrong, there are citadels in tower and smokestacks as well. Actually everywhere ;) But it's about time they implemend this feature.

thank you, chase

showcases just how important angled armor is.

thanks allot Chase!

Awesome vid m8! ;)

Q: Is it possible to penetrate through water? or is a shell terminated on water contact?

for calculating the effective armor just use this : armor in mm / cos (angle) = armor effective in mm easy right?

I just started playing World of Warships and I thought that the “citadel” was just another name for the bridge or whatever it’s called lol. I’m not very good with boats and ships... :)

Thank you iChase for the awesome tutorial! One question about the armor viewer, will it show the armor layout for all ships in the tech tree, or only the ones you unlocked/bought?

Great video iChase. Any chance of adding info about overpens? I seem to be getting these all the time in my Battleships against 0 degree side on cruisers; aiming at the waterline and I just overpen for a few thousand damage ;( Is it just a case of my guns are too big and I should be using HE? The shell normalisation patch seems to have made overpens much more of a problem (for me at least).

Hi! Can you explain the "german" turtleback armor, too? Is it visible in the viewer?

I know that this game is extremely advanced and realistic, but are all these features used in-game?

Not to split hairs too much, but when you are in a very long ship where your guns are more spread out, particularly IJN BBs, wouldn't your forward guns be at a different angle to the target than your aft guns? I have noticed this in game play: sometimes my forward guns all bounce and my aft guns all penetrate, though it could be RNG as well.

I've read somewhere in the wikiwows that between 18k yrd (16Km) and 30K yards (27km)n there's such a thing as an immunity zone (not invulnerability to be clear) because of the angle the shell will plunge at. it's probably what you're trying to get to at minute 19.00. But at the same time worldofwarships.eu/en/content/guides/training-advanced-3/ shows that at max range shells will plunge into the deck and pen ( ofc it could overpen and at that point i'll just DESKCHAN). EDIT : Decided i'm gonna link the source of the immunity zone i was mentioning earlier, which has everything to do with what iChase is talking about. wiki.wargaming.net/en/Ship:Gunnery_%26_Armor_Penetration. But i'm not gonna stop to that, and in order to help make iChase videos even greater (thanks mr.strimmer btw). I'm linking a forum post that does the exact same type of calculations and graphics about pen values over distance (pen curves), applied to a lot of the most relevant ships in the game. forum.worldofwarships.eu/topic/59528-armor-penetration-curves/ Hopefully changes haven't made them obsolete. Now, my question is, as i can't find the equation they use anywhere. How do you estimate then pen value of an AP shell ? I mean, obviously it's gonna be something like Mass(due to caliber) x shell velocity x or / something arbitrary they decided was good for the game. Am i lacking info ?

thanks for your work

I have to disagree on the north cal being hard to citadel up close ... I've been on both ends of the barrel and it's actually very easy do dish out citadels or to receive citadels from up close

thanks for the video. how do i know which angle am i shooting at? for example, im not sure if i were shooting at a 30 degree or a 60 degree...

could you disscus sometime shooting into the superstructure on a bow-on target and how it either bounces or pens?

hey Chase, do the gun barbettes not count as part of the citadel? Or when you penetrate the barbettes, it only knocks out your guns?

good work

Dang, you don't waste time. Nice job. ^_^
