SU 25T Vikhr firing problem - ver.2.5

[marcel1980]

I can't understand why i can't shot the Vikhr missile after i have a clear lock on target in daylight. No clouds, sunny weather. It happens very often and is absolutely annoying because the 5-10 seconds of additional flying are enough to get killed by AA fire from ground units. Sometimes i have to override lock to shot as its not going to fire at all. And yes im holding the button. Not just clicking. Also im in the minimum distance to shot missiles according to my HUD, so its not a distance problem. I have to hold the button multiple times to get at least one shot in cca 5-8 seconds

Do you activate the Laser? This is needed for the Vikhr. Remember that it can enter by itself in cool down (so it disconnects) and you need to activate it again for each launch.

 

I would recommend you doing the training lesson to check you've done everything right.

Yep i get the laser indication on left side of the HUD. Then i try to fire...holding button nothing happens for about 3 seconds. Release, press again - sometimes it fires but sometimes nothing. I have to try again. This way i fly too close and get shot down very often..

Do you place the Vikhr sight on the target so the missile can ride the beam? You need to lock it that way. Locking the Shkval alone with the laser is not enough.

 

You have to steer the plane and place the Vikhr sight on target. Then the seeking head will lock the beam and ride it to target.

Yep that was going to be my second advise.

 

Other checkouts to try, is your joystick fire button correctly inputting your key presses? (Try the keyboard button to discard any problem with the joystick)

This can be the problem! I have to try it out once i’m home. So the target needs to be in the circle all the time! I was not sure about this as i remember my missile fired also without this. Maybe i remember it wrongly

You don't need to have the target on circle all the time. The proper procedure is as follow:

- Switch to GA mode

- Select the Vikhr ordenance

- Turn on the Shkval sensor, search and lock the target.

- Turn on the laser when you are at missile max range. Watch out with laser cooling times, remember to turn it off between attack runs.

- Steer the plane so the Vikhr sight is on the target diamond.

- If everything is fine you should get the LA signal. Launch the missile.

- You can now change course, but remember to keep the Shkval sensor (and the laser!) on the target until the missile hits. You don't need to keep the Vikhr sight on target after the launch. In fact once you launch the sight with switch to the other launcher station, so it will be off target anyway.

 

Once you practice it you will see that the Vikhr is an amazing weapon, and you get 16 of them!

 

PS: If you still have issues, I really recommend you to fly the Vikhr tutorial mission. It is well explained.

Flashing LA is not enough, you need steady LA by ensuring that the small target circle is within the larger Vikhr circle on your HUD.

 

eta: also, with Vikhrs you don't need to worry about turning the laser on, it activates automatically when you launch the missile.

Looks like problem solved:). Circle not on target was the reason

glad you figured it out. sometimes the simplest things we forget.

To make aiming a bit easier enable 'Salvo Mode'.

 

Ostensibly this allows you to fire two missiles in one go but it also centres the big HUD circle which would otherwise be offset to the left or right.

[PeaceSells]

You don't need to turn laser on before firing the Vikhr, as a matter of fact the correct procedure is to haver laser off, if I remember correctly, as it will turn on automatically when you fire. After the launch, a countdown timer will appear on the HUD, indicating time remaining to auto turn laser off again. You can't fire another Vikhr before the timer reaches zero, unless you manually turn laser off (this way you can launch 2 or 3 Vikhrs in one pass).

 

Another thing you can do to increase the numbers of Vikhrs fired in one pass is activate Launch Override, so you're able to launch the first missile from 10 km away.

[Eviscerador]

Some interesting tips here folks, thank you very much.

 

But I wonder how is possible you fire 2 or more missiles in one pass, when you have to wait for the impact till you slew the shkval sensor to the new one.

 

Do you mind it is possible to launch from max range, wait till the missile hits, then slew to a new target, lock and fire a second missile, even a third?

 

I have to practice that :joystick:

Yes, exactly. Vikhr missiles travel very fast and you can launch the first one from 10 km away if you use Launch Override. But you need to turn laser off after the impact (while countdown timer is on the HUD), otherwise it won't let you launch another one, even with Launch Override on.

 

(Plus, with Launch Override on, you don't need to have the HUD circle exactly over the target in order to be able to fire)

Yes that's true! Thank you all for tips :).

I'm still getting downed very often in this mission however ;)). Im doing the Georgian Oil War campaign, i think its the 12th mission where allied forces advance. Somehow everytime they shoot me down i think Bradleys which is really weird. Are these vehicles and their canon really that good on air targets?

[PeaceSells]

^^ In-game, yes, they are, but only if you get close. With Vikhrs you can launch way out of their range.

[Tippis]

Bradleys are ridiculously dangerous to anything that comes close in DCS, but they also go off like popcorn at the drop of a hat.

 

So it's obviously very closely modelled after reality:

:D

hehe great. I think overal looks like vehicles with mounted machine gun which are not AA, are extremly dangerous in DCS also tanks which i think should be tweaked. If you imagine, pilots on older SU 25 without skhval, they had to get very close to ground targets to spot them visualy. They would be dead very quickly with such precison from the enemy.

[Eviscerador]

So I have been practicing the Vikhr multi launch in one attack run. After a few passes I'm able to consistenly fire 2 and most times even 3 missiles per run.

 

Thank you very much for all your tips. I just posted here to help a fellow Su-25T pilot and I left with way more knowledge than I brought.

 

Truly a nice community.

Anyone finding this an issue with the current version? Been using these since FC1 through to FC3 and the Ka-50 so pretty conversant with the procedure - but I've been going through the tutorial missions whilst testing my VR settings and found that I am completely unable to release the Vikhr missiles, regardless.

 

Not only that, the S25L missiles are also not launching. Every other guided weapon is fine. Really weird.

 

I'll try and set up some simple practice missions myself and see what happens in those.

[Johnny Dioxin]

I just tested all munitions on the Su-25T this afternoon, in a mission I set up for testing, and all worked 100%

 

Which means that the training mission is the problem - I'll go back and try again with the tutes. I know there is a problem with the Kh-29 tutorial mission pertaining to the time of day and lack of target contrast to the background - but this was not the issue with the Vikhr and S-25L tutorials.
