ciws shooting into the water
 

I have CIWS set to full auto, there's a missile inbound from a bomber coming in at ~90 deg to starboard, but the ciws fires into the water, and fires into the water on the port side. Am I missing something? Only way I can survive is by putting show truth on and using an SM-2 to intercept while the phalanx fires into the water.

Also, with show truth turned off, seems impossible to intercept with an SM-2. From the time I get an EW message, to assign as a target in weapons control, i'm usually dead. With the phalanx not working, makes it impossible to survive a missile attack, countermeasures didn't seem to do much.

Just a note, it wouldn't let me classify the missile as hostile in EW. It has friendly lit up in green.

Sounds like N. Atlantic Convoy, and the missile is an AS-4 Kitchen.

There are a lot of things going wrong that make this happen.

1. DW doesn't calculate lead very well for anything. This affects guns very badly.

2. The AS-4 is supposed to be a high-altitude weapon, but in DW it cruises below 300 feet, making it hard to detect on radar. It's 'normal' in DW to get hit by an AS-4 before detecting it on radar.

3. The AS-4 acquires its target from dozens of km away, but in DW all missiles have the same 10 nmi seeker...

4. ... compounding this problem, ESM sensors are set up so they won't detect missile seeker emissions outside the 10 nmi a seeker can acquire a target. So it's 'normal' in DW to get hit by an AS-4 seconds after detecting it on ESM... and before you're able to deploy chaff or fire an SM-2.

5. CIWS really can't handle super fast weapons like the AS-4 anyways, by the time it's in range it's already hit you (and even if you hit it, it still hits you--inertia is a bitch). The Navy devleoped the SM-2/AEGIS system for high altitude supersonic threats and the ESSM and RAM SAMs for low altitude threats. DW's CIWS more or less represents this in the final outcome, although the simulated mechanics leave much to be desired.

The good news is, LWAMI 3.10 corrects 2, 3, and 4. You'll see the AS-4 coming from 50nm+ on radar and get it on ESM the moment it enables. It's a sucker for chaff once you get early warning.

Sorry for the plug. :03:

Thanks!! Yup, it's the atlantic convoy mission. I'm using lwami 3.09. Haven't installed 3.1 yet. But yea, you hit it right on the head, EW detects it i'd say ~7 seconds before it hits. Radar detects it maybe 3 secs before it hits. CIWS doesn't seem to stand a chance.

Thanks, I'll give 3.10 a try.

So should I expect phalanx to have a shot at hitting when i install 3.10? Or do I need to use sm-2 and chaff?

No the CIWS most likely will still over/undershoot. :(

But you should still have sufficient Early Warning to blind the Kitchens with chaff.

Bummer, does the CIWS work for any of the missiles in the game? Or just doesn't work for the AS-4?

That's a real bummer if it doesn't work at all.

Oh, it's nearly 100% against anything subsonic. That's what I meant when I said the outcome of the CIWS model ends up about right. It gets the slow ones every time, and misses the fast ones every time. I doubt the real CIWS is 100%-0% but it's definitely meant for the slower ones.

The CIWS (in the form of the C-RAM) has shot down incoming mortar (and rocket?) fire in Iraq. I *think* those rounds come in at supersonic speeds. :03:

They're a lot smaller, too. Less inertia. It's not so much a problem of accuracy as it's a problem of hitting it after it's too late. CIWS doesn't have the range... RAM (Rolling Airframe Missile; not Rocket And Mortar or whatever that stands for) does.

NVM...

that's not too bd, but are most missiles in the game supersonic?

No, most are subsonic seaskimmers (Harpoon, Exocet, Noor, etc.)

Most ASMs are not. The C-801/802, Exocet, Silkworm (and relatives), and Harpoon are the most common ASMs in the world. They are all Subsonic.

The Sunburn, Kitchen, Shipwreck, Sandbox are Supersonic and used almost exclusively by the Russian Navy (with the exception of the Sunburn).

The N-27 Sizzler is one of the more common missiles you will encounter in multiplay (Akulas and some Kilos carry it). Its a two stage (technically three stage) weapon. About 5 miles from its target it drops its cruise stage and goes supersonic to defeat CIWS.

You wish it was just 5 nmi. It separates at acquisition, which can be as great as 60km.

As a whole it is possible to say about such feature is an inability of interception of missile with speed more than 1000 kts.
