SCUD precision


Recommended Posts

I think that's pretty normal for something that doesn't have GPS corrections and only relies on INS guidance during rocket powered flight, afterwards it goes ballistic

CEP = 50% of the shots should fall inside the radius, rest to go outside. But if CEP is 500 then it should be about 1000-1500 meters at maximum where you can have majority to fall in.

Last time I checked the accuracy seemed fairly reasonable, but the problem is it was incredibly precise - with missiles landing in the craters left by previous missiles. I'll have to do some more testing.

 

EDIT: Yep, still doing it - the missiles are always significantly off of the target, but they all hit the same place - they're inaccurate, but they're incredibly precise (and shouldn't they also account for the wind?)

Scuds aren't that accurate, for example in 2003 we were more worried about being hit by bits of one downed by Patriot than actually getting killed by a DH.

 

True, though in DCS it's a little more convoluted because they're very inaccurate (and don't seem to be compensating for wind at all - which might be the source of the inaccuracy) but incredibly precise.

 

But they all miss by the exact same amount - with subsequent missiles landing consistently in the crater of the previous missile.

I remember even news reports from back in '91 saying the military was not at all concerned about the SCUD's accuracy. Still, you probably wouldn't want one aimed at a city.

As far as I know, nothing has changed recently in regards to the SCUD's FM. 

You still get an error, if your launcher is placed on incline/decline. This is a bug, which has been reported many moons ago. That's why you can get huge offsets. 

Another issues is, the missile does not compensate for wind. If you have wind, it will blow it away.

Third issues is that, although you will get an offset, because of the two above mentioned issues, the offset its self will be consistent. Meaning, although you will miss, you will always hit in practice, the same spot.

Oh yeah, the accuracy is several hundred metres to a km, which isn't great for something with a conventional (albeit a fairly large conventional) warhead. My main gripe though is that while the accuracy I'm okay with (though it doesn't seem to account for the wind at all), the missile is extremely precise, they all land within a few metres of each other, I've seen subsequent missiles land in the crater of the previous missile it's that precise.

 

Just in case anybody is confused here's an illustration of what I mean:

 

The-concept-of-accuracy-versus-precision

 

I'd expect the R-17 to be more like the one in the top left (inaccurate and imprecise), with 50% of missiles fired to randomly fall within a 500m/1km radius around the target. Right now they're more like the top right bullseye (not accurate, but precise), only with even tighter dispersion.

Exactly this. It's very inaccurate (realistically the CEP means it isn't very accurate at all, but unrealistic in that it doesn't compensate for wind, I haven't tested it on an incline and I thought it needed to be placed on level ground), but incredibly precise in that all the missiles land in essentially the exact same place.

This Scud missiles are still very inaccurate. Also nothing can shoot them down or attempts to shoot them down.  

 

Please ED can you look at the scuds as I would use them more if they had some tuning and got engaged by air defence. 

 

Thanks for all your work.

Yeah, they're incredibly inaccurate (much more than the 1km CEP often quoted - I don't think they're accounting for the wind or launch angle), but incredibly precise.

So far I've had success with Patriot, I've seen it successfully intercept Scuds.

Hi Northstar98

You are correct, the test I did was using a Patriot site I incorrectly set up. Just to reiterate the scuds can be intercepted.

Thanks.
