[REPORTED]su25t sead weapons bug

[Kozmyk]

Miss and miss.

Splash damage is the best I could get from them.

[Winston 60]

I just became aware of this. So is SEAD completely broke right now or just hit and miss?

With the Russian anti-radiation missiles it is nearly completely broken, but the occasional kill is still possible. Before the bug I could always hit with 95% accuracy. Now it is down to 16%. I began to notice after one of the patches, the SAM sites were more aggressive in shooting down your missiles. Then this bug of the poorly tracking missiles appeared shortly thereafter.

Thanks fellas. Good to know I will hold off on that kind of stuff for Missions until it's fixed

[ZHeN]

today all my Kh-25MPU's hit targets to kill

but I had to launch them at very short distances ~18km

something has changed, really

[Rabb]

I tested extensively in the last days, with varying launch ranges and altitudes and there is no significant change. Even launching from 17-18 km. One out of four scores a hit at best. Most of other, but not all, produce blast damage. Missile veers away from the target in the last seconds of flight in most cases. Like it's chasing a maneuvering target. If it continues to fly straight, it hits a spot in the ground in front of or behind a target.

I agree. This bug should be put on "Double Secret Priority" for an expedited fix by ED. :helpsmilie:

from the last update 1.5.5 the k-58, 25MPU fail to hit the radars of SAMS , they misses with no connection on which height you released them . They always misses by 5- 10 meters, even though they are locked and in range.

 

It is frustrating !!

[robmlufc]

Any news on this? I keep getting asked to help out with SEAD duties and keep having to explain the bugs with these two weapons :-/

[BIGNEWY]

The devs are back from their holiday break so we should start seeing some progress soon, as long as it is not tied to any other issue not merged yet.

 

I will try to find out, if I am allowed I will pass on the info

[Winston 60]

BIGNEWY, I'm now thinking this may be tied to another issue. It seems NickD is having a similar issue with the KAB500kr TV guided bomb on the Su-25T. In his video it seems to show the bomb turning away from the target in the final moments before impact, missing the properly locked target with launch authorization. Could this be a bug of larger proportions?

Really interesting - I hadn't noticed that final turn. What are the aerodynamics of the missiles like - is that last-second turn enough to make the difference between hitting and missing? Because that sounds suspiciously like a negative-value bug.

 

Edit: Yes, it does signficantly change the path of the bomb - I plotted using tacview and you can see the estimated target position change:

The SU25T and weapons really needs some love. It's capabilities make it a unique aircraft in DCS :-/

[robmlufc]

Looks like there is an update to Anti-rad missiles in 1.5.6. Looking forward to seeing if this has fixed the problems.

[BIGNEWY]

yes, when you get it give it a go and then feedback here guys

[salling772]

hi bignewy

I did test both 58 and 25mpu fix is working but had a fouth missile 25mpu on the frist track that did not want to fire will try to recreated it later today.

 

terminal guidance on both missile can be adjust it still is trying to pull lead on stationary Target. but if this need a lot of code this will work.

[salling772]

test trakes

 

trakes

1.5.6 update test.trk

1.5.6 update test k58 vs cub.trk

1.5.6 update test 25mpu vs cub.trk

[Winston 60]

Are you guys saying the release version has now been patched to fix this? I'm not getting a release version update???

Only the Openbeta version got patched on Friday.

[inSky_1911CFZS]

Tested 1.56 OpenBeta Kh-58 and Kh-25MPU in instant action mission.

They still miss the target, although the probability of miss is lower, the missile still turns away just before impact.

And i noticed another behavior,which im not sure if it is a bug. I launched two Kh-58 at two target but they guide to one target. I tried this several times, same result.

Edit:Uploading the trk takes forever for me,sorry just can't attach it. Maybe someone else can do it.

[BIGNEWY]

thanks for the track salling772

 

 

We would like to see more tracks showing issues, I can follow up then with some data

 

the target being destroyed is the important issue here, my understanding is with proximity fuses the missile will look like it has missed sometimes but the target should be destroyed.

 

 

p.s The KAB500kr is a different issue to do with the wind.

Kh-25 MPU and Kh-29T not hitting targets

 

See this track file, I fired all 4 missiles in range, none of them hit...

[razo+r]

that's an already confirmed bug and WIP

[BIGNEWY]

merged the threads.

 

as mentioned before if you have tracks I can collect data, the shorter the better.

 

Bare in mind the weapons are not supposed to be a 100% hit rate, and you have the chance of having your weapon defeated by defensive fire

Seems fine to me, tested with HARM, KH-58 and KH-25MPU, they track fine. I agree with Bignewy, they shouldn't have a 100% hit rate, a slight bias in the guidance might be intended actually. Especially because DCS AI does not make use of shoot and scoot tactics, blinking the radar and all the other tricks.

Are you reporting on the release version or the open beta? For the release version I totally disagree. For the open beta, I have no experience with that version. Somehow input from people using the open beta is being posted in this topic, but as far as the release version is concerned, these two SEAD weapons (tracking and release cue ranges) are far from fine.

and please read this entire topic. Also please download and watch the contributed tracks. Our Squadron has been tracking this bug since Oct 2016 in the release version. Please post a track showing your experience of these missile being "fine" if you're using the release version. I'd really like to see it.
