Ship AA ratings

[RustyAction]

I have both Cleveland and Des moins and was wondering about AA rating. DM has full spec AA with am AA rating of 73.

On Cleveland im missing advanced fire training and manual fire control for 62. 

I would have thought the gap between the two much higher?

The numbers you are talking about are complete nonsense. They don't take into account a lot of things...

If you want the real run down on the ship, you need to watch or read CC guides like Flamu or whitemouse

Yes. They are absolutely useless. For example, there is no way in heck all T10 tech tree BBs have the same Survivability rating (100) despite many different features (Conqueror should have the lowest, followed by either GK or Repub).

One of the biggest examples of uselessness of the rating system is on Clemson. Top module Clemson have twice the guns than stock (from 4 to 8), but Artillery rating increases by a massive ONE point.

Cleveland AA vs DM AA can be a tricky topic, the two ships may have really close AA power overall.

It's difficult to compare anti-air capabilities between ships since there's many more variables now. Cleveland versus Des Moines is a good example - while Des Moines is certainly superior overall, she's not better in every specific instance.

At range zero out to 1.5km: Cleveland has 652 DPS versus Des Moines with 211 DPS. If you consider Cleveland facing a Tier 8 squadron and Des Moines facing a Tier 10 squadron, the difference is even more pronounced. On the other hand, this is only at point-blank range and might be of limited use in practice.

At long range, 4.0km to 5.8km: Cleveland has 155 DPS versus Des Moines with 163 DPS. Again considering their relative tiers, Cleveland wins here, too. Both ships output 5 flak bursts at this range band each with maximum damage being 1,330 for Cleveland and 1,680 for Des Moines. Relative to tier we could probably call the flak about even. This makes sense since they both share the same dual-purpose 127mm gun battery.

In the mid range, however, Des Moines reveals her true power. 1.5km to 4.0km Des Moines has 875 DPS, 11 flak bursts, and each does up to 1,400 damage. Cleveland 1.5km to 3.5km has only 280 DPS and 7 flak bursts each doing a maximum of 770 damage.

All these stats are without captain skills, upgrades, flags, or consumables (Cleveland with the top hull, though). For escorting other ships Cleveland is arguably better than Des Moines. For self-defense, Des Moines is a much more lethal adversary for a CV to tackle. A simple "AA Rating" in the port window cannot convey any of this - you have to look at the details.

The ratings means nothing. Only way to tell is using the ship and finding out. Ive used IJN ships that did more damage then US cruisers and my Worcester with NO AA equipped shot down 24 planes compared to 8 with everything equipped.
