either AI planes are good or SM-2 isn't
 
Was playing a carrier escort mission where a fair few Chinese fighters came in at high speed. Even at almost point blank range the fighters could out maneuver the sm-2 from the perry.

I even saw a Badger escape one from well within range.

Maybe jamming does work as I have link data turned off but I'd have a good track on a fighter but it's position would jump about a little bit and flicking between show truth and no truth it did seem to deviate quite a bit.

Also I know this is sick but tried to run over a rubber raft with a pilot. No joy can't even shoot them.

Are you sure you just hadn't tried to fire at a range very close or below the RMIN of the SM-2? :D

But I suspect the problem is because of the auto-TMA. IMO, it was probably a mistake to try and handle all targets with the TMA system. TMA is mostly meant for a bearing-only systems - with ranging systems you are better off just reading the ranges direct.

I don't see where TMA comes into play here. He's talking about radar.

ASWnut101 03-17-07 03:53 PM

Yeah, don't fire your SM-2's at close range. They simply don't have enough time to moneuver into an intercept position before passing the target. Usually, that will happen in CWIS/CIWS range, so....

Mau 03-17-07 07:46 PM

And that was one of my point.
We need the 76mm at close range for AAW.

But unless we change it, it doesn't really work.

I think we need to change it from bullet to shell (or the other way around)

Not in real life, but in DW, everything, including the radar plot, is integrated on the TMA plot. Due to the funny ways auto-TMA works, it doesn't handle radar data as well as it should.

TMA should only be used for passive, bearing-only sensors. If an active sensor is being employed, its range data should be treated as "gold" - but that's not what happens with DW auto-TMA.

Well the Fire Control radar should give the missle a target, regardless of how bad the TMA is. Does anyone know what info is fed to the missles? It looks as if it must be radar data, or the missles would be way off.

I'll remember that if I ever play with auto-TMA. I don't even recall being able to manipulate a radar contact in the TMA station. If it's doable, that is rather strange.

XabbaRus 03-18-07 04:31 AM

This wasn't at close range it was at medium range, not too far to out run but not in CIWS range.

It is nearly impossible to manipulate anything properly with that plot. There is a reason even many manual-TMA guys suggest that you fall back on the auto-TMA when you play the frigate.

The idea of throwing everything onto the TMA sheet, as I understood it (I think they mentioned it in the manual), is to allow you more opportunities for data fusion. For example, you may have a ESM track that verifies a plane's a Tu-95 Badger, and you fuse that with the radar track of the same plane so you don't have two symbols flying over the map.

In the P-3, if the ESM and radar detect the same thing, you'd be left with two symbols on your chart, because of the lack of the TMA station. So it was a good idea, except that the TMA is really for passive and they should really have put the "Merge" button in the Tactical Coordinator screen instead of the TMA screen.

Speaking realistically, if the position given by the combat system (represented by the TMA plot in DW) is too far off the real position, the CWI will not elevate and traverse to the correct position to put its "flashlight" on the target, or it will illuminate with only a sidelobe - in which case the missile will not have enough signal to home.

I don't think it's modeled that way at all. I think the missile just flies pure pursuit on the truth object/target (perhaps with some lead, but certainly not the proper amount) provided that the FCR is assigned to a contact associated with the object/target.

Dr.Sid 03-18-07 12:22 PM

Yes .. SM-2 is simulated as stand-alone full-active guided missile. It just uses special flag that it requires FCR to operate.
It uses 'Weapon radar' sensor, which report all speed, altitude, distance .. if there is some problem, it must be in TERMINALHOME doctrine command. It's hardoced and it cannot be moded.


Anyway my SM-2s flies quite OK .. Xabba .. what about some mission + save ?

ASWnut101 03-18-07 04:33 PM

Why'd they do that? Not very realistic, if you ask me.:cry:

Dr.Sid 03-18-07 05:15 PM

Everything in DW is as simple as possible .. most is simpler that it looks and pretty everything is simpler than it could be or should be.

It's still the best anyway. Let's not whine.

But all the sugestions give sense. Something can be modded, something can be taken into account while designing new software.

kage 03-18-07 06:09 PM

There are the occasional planes that pretty much outrun the sm2 though.

See the map up there - those missiles were fired after each other, and then the target sped up and turned. The history trail seems to be gone though - and I don't have the original picture anymore, I think.

The overtake is down to only a small fraction of their speed, and the missiles are there on a heading around 90 degrees off the direction they were fired in.
