Jutland - AP?

Jutland gets enhanced AP pen angles, somewhere between the RN CL and USN CA angles. This means Jutland AP pens instead of bounces at much steeper angles than other DDs. At any kind of broadside ish angle, and even nearly bow on you can still get pens reliably. You should absolutely use your AP when the angle is flat at all because it will boost your damage considerably, even if you have IFHE.

Don't forget to use it on cruisers and Battleships as well. Unless you are trying to start a fire after a confirmed damage con, the AP can reliably land 2k volleys on the broadside. They really really add up quickly.

AP does more damage to broadside destroyers, but if they angle you'll lose damage either firing a 0 damage AP salvo or forcing a reload.

It's worth using, but HE is the safest option.

eta: Jutland AP isn't that different from other DD AP, it can just hit at steeper angles without bouncing (and it's small enough to arm on 19 mm, unlike 127 mm guns that need a bit of an angle). Kitakaze actually gains much more damage than Jutland from shooting AP.

AP shells have better alpha than their HE counterparts, so most of the time it's worthwhile to use AP on targets you can penetrate (broadside DDs, upper belt and superstructure of broadside heavier ships).

I generally use AP on target that's broadside and unlikely to change that anytime soon (grounded, stationary or has to angle against bigger threat), but against a maneuvering or angled target you're better off with HE for consistent (if lower) damage. Also, HE eventually saturates the superstructure resulting in no damage, with AP you can count on overpens, as they ignore saturation.

As for T9 DDs:

• Jutland - the alpha difference is fairly minor ("mere" 20%), but you get better bounce angles meaning more consistency

• Kitakaze - the 100mm HE is fairly pathetic, the AP.. isn't, the difference is something to the tune of 50%. Be warned that the shells lose penetration ability rapidly, beyond 10 or so km lies HE only territory.

• Z-46 - crap HE, monster AP, literally double the DPM (AP reaches almost Kitakaze levels - 270k vs 272k stock). Anything showing broadside gets eaten alive. The problem is - again, your pen isn't anything special.

• Fletcher and derivatives: Eh. DPM-wise similar situation to Jutland, but crappier arcs, penetration and don't get the better bounce angles. Still not to be underestimated.

• VMF DDs: Iz gud, komrad.. not to Kitakaze/Z-46 level, but better than the rest of the pack (Jutland only gets a break thanks to its RoF and angles) and retains the penetration better than any other DD.

• Yugumo (or really any IJN DD with 127s) - now there's a ship you shouldn't use AP on. Very spicy HE means little incentive for AP use unless you can get citadels, and THAT means close quarters with Neptune/Seattle/etc.

Use AP on broadside DDs. Yes, you may break more modules with HE shells, but look at the numbers: AP shell hits 2100, while HE shell hits 1700. It might not look much of a difference at a glance, but if you look at DPM the difference becomes magnified: 174828 for HE, and 215964 (calculations are done based on Jutland's base DPM, does not include BFT and/or Main Battery Mod 3). Jutland's strength lies in its DPM to quickly finish off other targets, especially DDs, so using AP shells against broadside enemy DD further maximizes your advantage. Also, against a broadside DD, I don't think the AP ever over penetrates, it's usually full penetrations.

Jutland and Daring get "babytaur" AP, with the same filthy results due to the improved penetration angles. Absolutely use that AP whenever you see broadsides.

If u have ifhe then u dont need to shoot ap. Use it on broadside targets even dds. If u dont have ifhe ur he cant pen most dds u will meet so u have to use ap mostly

In my opinion using HE is superior to AP on Jutland when fighting DDs. The alpha damage difference is not as significant. If from one AP volley, only one scores on overpen instead of a pen you would've done better with HE and it gets only worse when you start getting bounces. That plus the fact that HE also sets fires and breaks modules, thus forcing DCP from the target makes it far superior.

Only use AP on broadside BBs and cruisers since your HE can only pen the superstructure.
