Are small CIWS any good?
I am trying to make a small CIWS turret, but every time I do they just seem plain bad in comparison to other options. I want them to be relatively small but it seems they need to be as big as a main gun to really do anything. I want a way to reliably kill off large cram shells without sucking up a ton of juice from my lams. I really want CIWS to be good, but they just seem really bad at killing anything other than my available deck space. If anyone has any tips on how to make them effective I would love to hear it. I am starting to think the best option is to use them as decorative items that aren't really supposed to do anything. If someone has had good luck with them I would love to hear how to build them.

then a pair of CIWS each sufficient to negate all the CRAM the Onyx Watch can send. With a pair of CIWS, you can turn CRAM into a non-menace entirely.

I would love to hear more about these CIWS! Caliber, shell composition, rail draw, gun size. You know, everything I would need to know to replicate it and hopefully learn how the heck to build a good CIWS.

He mentioned the cram that Onyx Watch uses, Onyx Watch has extremely bad crams for the most part that are low health, often come in volleys, and are usually mostly payload with little to no hardener. This means that area of effect options such as interceptor missiles or flak are ideal for defeating them. You likely don't even need to make a dedicated anti burst CIWS for this and could just use some normal 50mm 500m/s or so 1m long flak rounds to deal with it.

When using flak you don't need much speed since there's no AP value you have to reach and you have a decently wide area in which you can miss the shell but still hit easily with timed fuses. You also should not add any recoil absorbers because the spread will not matter so it is just wasted cost, low vel means less coolers required too, make sure to make the gun 6 barreled for extra cooling bonuses ontop since the accuracy penalty for multi barrel once again doesn't matter here. This lets you maximize on loaders, you can either pick to go with something like normal 1m loaders with up to 5 clips attached to them for a cheap but somewhat volume inefficient package that never has to stop firing, or you could look into a more compact beltfed setup that focuses only on shooting down enemy munitions and not firing when there are none so as to save on ammo before reloading then hope you've disabled the enemy or at least its munitions before you need a reload.

Each of these is worth 45k mats, so they are very much overengineered for threats smaller than the Black Current. The ship they're protecting is 800k-1M range in cost and designed to outfight pretty much anything short of the biggest Scarlet Dawn flyers with a major restriction: no futuristic energy weapons whatsoever (no laser, no PAC, no railgun). These CIWS themselves were calibrated to stop a saturation attack of 20-40 fast suicide nuke cruise missiles, which is very much NOT a regular threat either, but fitting the theme of the real world modern FFG/DDG.

So, not exactly "small", except in calibre: 50 mm with 20 component shells, 90 % are 17 gunpowder, one AP, one solid, one fin, 10 % are 17 gunpowder, one tracer, one fin. A sandblaster gun.

These sound like you just have them setup for anti air duty rather than CIWS purposes, since the nuke cruise missiles are essentially just kamikaze aircraft rather than a munition proper.

Yeah, OW CRAM shells aren't optimized in any way, it was just an amusing side effect from the overengineering to see large salvoes of these shells being disintegrated easily. As indicated, the requirement was to provide an inner layer for Black Current salvoes, both when they were nuclear-suicide crafts and after they became huge missiles.

Agreed that flak is pretty damn good, and IMO used well as an outer layer for your Integrated Air Defence System, since it will hit several missiles from the incoming salvo at once, and even misses will likely hit some part of the salvo. For this, I use a 305 mm at 80 RPM which tends to thin a lot of inbound missiles quite well, but I must emphasize again that one of the most important parts of missile defence remains proper use of decoys, which are insanely cost-effective if used well, removing most radar-guided threats entirely.

They're dual-purpose, yep though I wouldn't rely on them alone for flyers that are much bigger than real-world fighter jets, the damage doesn't add up fast enough against armoured flyers. That's a role for medium missiles and the 305 when its target analysis setup decides to use fast APHE shells to kill the flyers (it switches on flak only if it is targeting a small and fast target or when there are missiles in flight and the main target is either submerged or really huge, when a 305 wouldn't really help).
Carolus Rex 2022 年 7 月 27 日 上午 4:33 
One trick that can help a lot against larger missiles is to have your main or secondary weapons double as CIWS. This works best for lasers, but can also work for APS if it is set up right for it. I would also recommend setting it to only target larger missiles if doing this with higher gauge APS.
Hensley 2022 年 7 月 27 日 下午 1:24 
how do you actually get them to hit their target? Mine always seem to be just behind the incoming round.
The man, the myth, the leg 2022 年 7 月 27 日 下午 1:39 
are you using heavy barrels?
they slow down your weapons aim
CIWS need to aim fast so use regular barrels

Thanks for the details on that! It is certainly many orders of magnitude larger than I was going for. However I really like the Idea of no future stuff! That is a cool build restriction. Thanks for sharing the details of them. It will be useful when I resume my quest for an effective CIWS. For now I am taking the LAMS and small/medium interceptor approach. I feel like CIWS needs a buff to justify replacing an entire gun with it. When I think of a CIWS I think of a relatively small ultra high fire rate weapon. That concept does not seem to translate to FTD very well. Especially considering that the game has a hard cap on fire rate because of physics steps. I don't think small CIWS are even capable of achieving a volume of fire that would work all that well. But that could just be me being inexperienced.

It's possible to make ultra-high firerate small APS with beltfed autoloaders, but that's generally a pretty questionable idea with CIWS in particular. Beltfed ALs give you massive fire rate and load speed in a very small footprint, but the cost mechanically is that they don't reload until they are completely out of ammo. The result is that they give you bursts of incredibly high fire rate, but then don't shoot at all while they are reloading the gun from zero. Obviously, this is a very bad thing with CIWS typically since it can leave you with effectively no CIWS at all for a period.

However! You can kind of counter that weakness by manually setting the fire rate lower, cutting back on your cooling to match, and putting extra ammo inputs on the ALs and clips. If you do it well enough, you can get to the point where the first AL's clip that runs out is done reloading by the time that the gun gets back to it and keep your firerate steady. You lose some of the space savings from going beltfed, but not nearly all of it.

It's not something I have a lot of experience with personally, but I do have enough to know that it works and I know there are other people who use it a lot. It might be worth asking around about it in particular for details.

Beltfed autoloaders actually do not have to load from empty. They have a timer from the last time they fire to start loading again. If you set this to say, 5 seconds, it will generally start reloading and be ready again by the next enemy salvo. This is why beltfeds are ideal for CIWS because what you want with CIWS is generally large volume in a small time with longer idle periods.

You can set that? Huh, I didn't realize. Well, I did say that I don't have a lot of experience with them, I guess this shows it lol. I'll have to look into that.

EDIT: Well color me happy, it's true! Not that I doubted. This definitely means the answer to the OP's main question is "yes if you use beltfed autoloaders" then, lol.

Just FYI, this gun uses belt-fed autoloaders already, so it's not going to cut down the volume much more for a 50 mm gun like the one I showed (you'll have to go down to much smaller shells, but then you start having issues killing the missiles fast enough to retain effectiveness, IMO). His point was to have more like a bolt-on gun like various RL CIWS, from what I understand, and this... isn't going to happen in FtD with any level of effectiveness. The best I could do was to do some unholy amount of clipping to get more than 20 simple weapons (the 30 mm autocannons) in the same place and staggered to simulate a high ROF gun. The gun below is actually a couple dozen simple weapons in a single bolt-on position:

Guess what? It's a BAD weapon. The projectile speed of the autocannon is so low this thing is useless outside doing pretty fireworks despite firing at rate similar to my actual CIWS'.

Yeah that is a pretty accurate take away. The real life CIWS that the USA uses has a fire rate that is about twice as fast as is even possible in FTD. Also it is relatively small at like 5ish meters tall. There are only 40 physics steps a second in FTD, and that locks the possible fire rate at 2400RPM. It wouldn't matter if it is a simple weapon or advanced cannon. That's why I said the idea of CIWS does not translate to FTD very well. In FTD the gun needs to be really big to be effective. The fire rate does not matter as much as size. So the concept of small caliber and high volume of fire hits a stone wall so to speak. The needed volume is not achievable without more physics steps. It kinda sucks, but that's ok, I get it. There are a lot of reasons why allowing for realistic CIWS would cause problems in terms of balance and performance. The whole simple weapons trick you pulled of is both hilarious and really cool. Other creative solutions like that could potentially solve the volume of fire problem.


Update: Ignore that whole bit about 2400 RPM being the maximum. It is certainly not. I had thought it was. The APS firing piece says it is, and I remembered seeing somewhere withing the game that FTD has 40 physics steps per second. But I figured I would double check and I have no clue what the maximum fire rate is now. Guns act kinda strange above 2400RPM, but they both do more damage per second and expend more rounds, so I would say they can fire faster than 2400RPM.
