The probability of a critical hit that leads to damage increases for lower module HP values. Shell's in-game tracer may not coincide with the actual trajectory, in order to better visualize the shooting process. In order to be able to use all the functionalities of our platforms, you must agree to access the API. Welcome to IFHE. a value that describes the lateral distribution of the shells relative to the player's ship. This phenomenon is called dispersion and, irrespective of human and constant error, it is caused by multiple inherent factors: minor variations in the weight of the projectile, differences in the rate of ignition of the propellant, variations in the temperature of the bore from round to round, physical limitations of precision in setting values of deflection and quadrant elevation on the respective scales, minor variations in wind, air density or air pressure, and so on. 152mm - Take IFHE. Each compartment (except the citadel) has two thresholds, where after each one is reached the damage it receives is reduced. The magazines are normally located just under the main caliber turrets. As of 0.4.1 the underwater hits do not cause flooding. The total hit points value for all these compartments combined is slightly more than the ship's nominal hit point pool. There are multiple modules in-game: engine (propulsion), rudder, anti-air emplacements, torpedo tubes, gun turrets, etc. Contact EdibleBug on Reddit for service related issues. The distance at which both plunging fire and direct enemy fire is less effective is called the immunity zone (IZ). 283mm - Put IFHE down, Spee. If the cruiser is far away, or is angling too much, use HE; HE should also be used against the destroyers in practically all situations. 16 shells per salvo, 4.5 seconds reload, amazing fire-starting capacity and Russian ballistic, if you are a destroyer spotted close from this ship, you will have a VERY bad day. This approach of providing either total or negligible protection is referred to as "all or nothing". A shell may still cause damage after the ricochet, but only to the same ship. Damage from fire, flooding, ramming, over-penetration and citadel hits will not reduce any compartment's HP pool (but they will still reduce the ship's total HP as normal). Builds for specific ships are mentioned at the bottom of the guide. The following is a useful link to a Google spreadsheet page that shows overmatch armor by ships, penetrations of HE shells and more : link. The following tables are as of 0.8.6. In case the change is adopted, IFHE is automatically reset for 4 skill points. The dotted line is the normal distribution generated from these results. Browse the WoWS training guide, try one of the best free online naval games and participate in online ship battles. The fuse of the AP shell is initiated after it passes through armor, and historically the fuse times were calculated in a way that would allow the shell to explode after traveling about ten or so meters after passing through the armor; that way the shell exploded around the middle of the battleship. 127/6 = 21.16667, which is rounded down to 21. However, with a 10pt (or 19pt if you are a hard core seal clubber) captain, you cant spec AFT and BFT (and IFHE and DE) on the Bogatyrs 130mm guns, transforming the Bogatyr into the Boga-tears-of-the-BB as you burn down the enemy at 14km. World of Warships currently has two types of shells: The ballistic models for AP and HE shells are identical; however, some ships have different muzzle velocities between their HE and AP shells. 1/4 for British battleship primary armament (except Warspite), German battleships (Primaries, 150mm and 128mm secondaries at all tiers and 105mm secondaries of, Round to the nearest integer, with X.5 usually rounding. Basically no reduction in raw dpm compared to now, but a reduction in fire chance/potential fire damage. Citadel hits will always deal x1.0 of the shell's listed damage (though citadel over-penetration is still possible, and will only deal x0.10 damage). Unlike HE, the AP shell does damage only if it penetrates the armor. Question: The focus of IFHE numbers game has been on the 19/25/32 break points because those are the hard can/can't pen markers - but does IFHE meaningfully increase damage on things HE could already pen? Clones and duplicates will not be listed twice, for them refer to the original ship (e.g. All copyright materials provided by Wargaming.net are owned by Wargaming.net. Most ships use the following angles for AP ricochets: As of 0.7.6, no ships have "worse" angles. Find out what is the full meaning of WOW on Abbreviations.com! However, based on the user collected data we know lines of tech tree ships are tied to specific formulas to determine horizontal dispersion. Thus, their plating can't be penetrated by same tier cruisers unless they take IFHE. 203mm - Don't take IFHE on 203mm armed ships. To see the final cost, click the button for the selected payment method. ; 2020-04-30 Google Ad enabled by default while making adjustment. 2021-01-24 0.10.0.0 commander skills are updated. Since their armor thickness will be nowhere near that of a battleship, angling will affect your AP shells to a lesser degree. AA emplacements). The muzzle velocity for a new gun and a full charge is 762 meters per second. Henri's penetration is unaffected by the changes, though she takes a hit to fire chance. AP against a destroyer that suddenly materialized near your ship) than to start a long half-minute reload. it gives a value where 50% of the fired shells will land around the point of aim. The graphic below showcases a high sigma (blue) and an average sigma (red) and their respective distribution of shells on the horizontal axis. 152mm - Take IFHE. It is impossible to get a citadel hit on a destroyer, as they no longer have them per se (it was removed in 0.2.4/0.3.0). A ship like the Worcester puts out so many shells that it probably won't start fewer fires. Remove the Accuracy Debuff when getting Slowed by Stasis. This page was last modified on 21 January 2021, at 22:49. This is not a bug. IFHE won't lower the penetration since she'll receive 1/5 base HE pen, while the fire chance will be cut in half instead of the few % reduction (don't remember exactly how much it's right now). Therefore, upcoming games with a mere announcement and no discernible release date will not be included. Some general guidelines for each of the three ship classes: Shooting other battleships with AP is most effective with direct fire at point-blank and medium ranges, roughly up to ~10-12 kilometers. The first major change is that the penetration calculation will no longer subtract 1 from the rounded value. Your email address will not be published. Against other cruisers and carriers use AP shells at close and medium ranges, when you can reliably hit the citadel: a well-aimed salvo remove as much as half of the other cruiser's HP. If the armor thickness is less than 1/14.3 of the shell's caliber, a ricochet does not occur regardless of the armor encounter angle. From the citadel box, shafts known as barbettes lead upwards to the ship's main gun turrets and conning tower. This is an advantage of some spaced or turtleback armor schemes. WoWS Stats & Numbers - best online tool for stats browsing and progress tracking for World of Warships. T1-7 ships will have a 25% bonus to penetration, while T8-10 ships retain the current 30% bonus. Its Mark 21 Base Detonating Fuse (BDF) had a delay of 0.033 seconds. Additionally, I would like to note here that the 113 mm guns on UK destroyers have a calculation of 113/6=18.833 mm, which rounds to 19 mm for the shatter thickness. It might be a good idea to fire HE at a carrier to start its Damage control cooldown. A shell that destroyed the ship's laundry room or the galley in an artillery duel would have much less of an immediate effect on combat capability than a shell that hit the magazine or the engine compartment. Thus, 21 mm x 1.3 = 27.3 mm to shatter the shell. If a ship you would like a build for is not listed, feel free to ask. for ARP Myoko refer to Myoko). Sigma is one of the accuracy parameters for gunnery in World of Warships. The enemy battleship shouldn't be at too great of an angle; ideally, it should be perpendicular to your line of fire. These shells have an instant fuse and burst immediately upon hitting a target. See also: Damage Saturation for an in-depth explanation. A ship has to be both a military base and a combat vehicle, since it is designed for long autonomous operations. Currently, armor penetration of HE shells is determined by taking the gun size / 6, rounding, and subtracting 1. This phenomenon is called overmatching. Therefore, if the shell were to immediately hit an armor plate 1.5 inches thick after exiting the barrel, it would explode 762*0.033 = 25 meters after passing through that armor plate. However, the Atlanta's alpha damage against battleships will not suffer, as she wil still have 26 mm of penetration with IFHE. Sub-optimal damage is better than no damage at all. Armor in World of Warships is not just a uniform barrier to be pierced (like in World of Tanks), but rather a kind of multi-layered “cake” that covers a number of construction elements and mechanisms, each having specific armoring. As well as... First Gripe. It is a LARGE list of ships by the way. She drops from 22% base fire chance to 15% at the very most. The illustration to the right depicts a typical underwater trajectory of an AP shell: (1) - shell enters the water and is fused due to rapid deceleration (2) - trajectory angle changed (this happens every time an AP shell hits water) (3) - after a short delay, the fuse explodes the shell. Tier VIII Japanese Cruiser Mogami Replay Related Ship… Continue reading Mogami is not an exception, and will thus have a 2.0 sigma as a Tier VIII cruiser). All rights reserved. An AP shell that ricochets after penetrating armor will cause another instance of penetration damage in the section where the ricochet occurs. Third, the IFHE value changes. Theoretically HE will never over-penetrate due to its low detonator threshold and shorter fuse. Prior to 0.4.1, penetrations on a destroyer's midsection will deal x0.5 of the shell's listed damage (in lieu of the absence of citadels), however this is no longer the case and penetrations to it will deal the standard x0.33 of the shell's listed damage. IFHE All Night Long by LittleWhiteMouse. Devblog Wows. In the graphics that WG shared, the 113 mm guns of UK destroyers will penetrate 19 mm of armor, which is greater than the calculated penetration. Armor in World of Warships is not just a uniform barrier to be pierced (like in World of Tanks), but rather a kind of multi-layered “cake” that covers a number of construction elements and mechanisms, each having specific armoring. In addition to any direct damage, HE shells are good for knocking out modules, particularly deck mounted ones like AA emplacements, as well as starting fires, which can deal a large amount of damage over time if not extinguished. Properly angling the ship matters a great deal when the enemy is shooting AP shells: when an AP shell encounters armor at an angle, it has to pass a greater amount of armor for penetration. 180mm - Take IFHE. The ship's magazines are located in or around the turret barbettes, and contain the main caliber shells, as well as the gunpowder charges. With the addition of IFHE, such ships can citadel her with shells exceeding 230 mm diameter. Each module has a certain amount of HP. Commander Skills World of Warships - full descriptions for the WoWS commander skills, play the free multiplayer pc game about battleships with your friends Thus, with IFHE it would take at least a 33 mm plate to shatter her shells, while armor of 32 mm or thinner would be penetrated. Ones that fire AP did exist, but have been replaced by HE in patch 0.7.11. Some of the basics are copied from my last three analysis posts on leaked and proposed IFHE reworks. The higher the Sigma is, the more likely the shells are to land closer towards the center. Therefore she can shatter normal HE shells of up to (75 + 0.5) * 6 = 453 mm diameter, but she would be citadelled by shells of 454 mm or larger. This is the thickness of armor that will shatter the shell, so penetration is 20 mm. This page has been accessed 264,274 times. On the other hand, if the shatter threshold is strictly greater than the thickness of the armor, it penetrates. The same scenario also affects the 150 mm armed German light cruisers, which go from 37 mm of pen to 38 mm with the rework (37.5 mm calculated penetration for 1/4 pen). The final cost of virtual goods may vary depending on the selected payment method. 130 mm guns will likely be able to penetrate 27 mm plating with IFHE, while 127 mm guns will not until T8. As 27 mm < 27.3 mm, IFHE 127 mm guns can penetrate 27 mm of armor. Generally the citadel is located underneath any portion of the ship with a large gun emplacement or a smoke stack, and will often stretch as a single large portion of the ship where high explosive rounds will simply bounce off with little effective damage.Given the proper aim a citadel penetratio… below 4km) dispersion values for all ships. Commentdocument.getElementById("comment").setAttribute("id","af985a03624ffec805e0ba23c5116e9c");document.getElementById("e6d8880a7e").setAttribute("id","comment"); Save my name, email, and website in this browser for the next time I comment. (Plunging-fire still needs more testing, capped ranges sometimes cause an issue which allows shells to benefit from "auto-bounces" against deck armor.). 2020 … Every time a player orders his main caliber guns to fire, the game engine constructs a 2-D ellipse around the point of aim, and does so independently for each salvo fired. IFHE will help every calibur up to 155. Feel free to opt in or out. This has been confirmed by experiments conducted by the players. Regardless of the state of the compartment, over-penetration will always deal x0.1 dmg and citadel hits will always deal x1.0 damage, even after the compartment's HP pool is completely depleted. A damaged module loses function until it is repaired, a destroyed module cannot regain function. After the first threshold is reached, the damage received is halved (x0.165 dmg for shell penetration). In some cases, when they hit an "empty" section of the ship such as a torpedo belt, they can even fail to do any direct damage at all. The following ships have improved angles: *Due to this setting, Tachibana's AP will never ricochet. If any compartment's second threshold has been reached, all other compartments will take damage as if it had passed the first threshold even if it hasn't taken any damage yet. A good example of this is 127 mm guns. 127/6 = 21.16667, which is rounded down to 21. For ships which rely on fire damage IFHE thus can be a poor choice even if significant armor thresholds are passed. The threshold levels for each compartment of each ship varies. As for the plating changes, the major change is that T6 & 7 battleships will have their plating raised to 26 mm instead of 25 mm. If the thickness of the armor is equal to or greater than the shatter threshold, the shell shatters. | Privacy Policy | Contact Us | About Us |. Non-penetrations (bounce/ricochet) will always deal 0 damage, regardless of AP or HE (the latter cannot ricochet). What do you plan on doing? However at close ranges, secondaries will likely hit the main belt of the enemy ship. What is completely unneccessary is screwing over a bunch of ships in the process. It is set to -1% for light calibers up to 139 mm, and to -8% for the rest. You just need to learn which ships you can take advantage of with it. Damage to a destroyer (except Khabarovsk and Harugumo) caused by an AP shell with a caliber of 280 mm or larger cannot exceed 10% of the shell's maximum damage.[1]. Dispersion values are same for HE and AP shells of the same gun. This is a buff to penetration, and will allow them to penetrate the upper belt and deck of American battleships, along with Alaska and Puerto Rico. In addition, each ship's model in the game is assigned another, virtual compartment called "entire hull". Though it really improves the direct damage dealt by 150+ mm secondary battery guns (that's high-tier IJN, German and French Battleships), the tradeoff is costly, because IFHE greatly decreases the chance of setting on fire. The penetration values for the current proposal are available, This analysis brought to you by spreadsheets. How can a player know where these important compartments are when he or she fires into the side of an unfamiliar ship? In this regard the developers attempted to adhere to historical realism and simulate all significant layers of armor. AP shells should be used against well-armored cruisers and carriers as well, when you are certain that a volley at the waterline will penetrate the citadel. Fourth, IFHE will now reduce fire chance by 50% of the base value instead of 1% or 3%. Shell impacts within the dispersion ellipse are not uniformly distributed over the surface, but lie more thickly towards the center of aim. However, some carriers have enough armor to resist HE, and AP should be shot at them.

To be eligible for the list, the game must be confirmed for 2020, or there should be good reason to expect its release in that year. The greatest thing about this game was that I... Why you associate yourself with someone like that I... Hey, I really love this story. As such, shells fired to strike the deck may be able to defeat the armor while those same shells may be incapable of penetrating the side armor of the target vessel. As a rule-of-thumb, when you have a clear shot at the side of the ship, aim in the middle of the ship (just below the smokestacks), and close to the waterline. The intensity with which the shells fall in different points of the area of dispersion, can be described by a Gaussian (normal) distribution. You might also get some citadel hits with plunging fire at maximum fire ranges. Therefore a significant portion of the ship's interior space is needed for the every-day activities, but has no direct effect on ship's fighting capacity in the critical moments of the battle. Reduced effectiveness against tier VIII+ battleships. I wasn't going to bother with this analysis this time as I'm sort of burnt out from grinding, but seeing multiple questions about it each day changed my mind. When driving most destroyers, your main weapons should be your torpedoes (especially so if you're driving an IJN DD). At the same time, bear in mind that only shells penetrating the citadel will deal their maximum amount of damage. Leaderboards, ships statistics and configurations, ranked … Note that HE shells can only ever penetrate at most a single layer of armor. Consistent HE hits and nonstop fires are a bane of many battleship drivers' existence.
