Su-25T - Long delay after first Vikhr impacts before can launch second

[guitarxe]

Is this a bug, or something I don't understand? Once I have launched a Vikhr, and it has impacted on a target, I then lock on the next target, but I cannot launch another vikhr for maybe another 5 seconds.

read the manual. there is a reason.

There is no such thing in the manual. In fact it actually mentions that you can launch Vikhrs in pairs. If you are referring to the laser cooldown, that is not what's happening in my case. The laser is still active and does not require cooldown yet.

I know only about the Vikhr deployment with the Ka-50. There you need to wait until the laser cycle is finished and the cooldown has occured before you can launch an other missile. The laser lases for a time period that covers the flight time of the missile plus an additional 6 seconds "slack". You can end the lasing cycle prematurely by resetting the laser (or turning it off/on) - so you can save those ~6 seconds in the end (the shorter the lasing time, the shorter the cool down time!).

At approx. 17:00 he does a 3 target 1 pass execution...wit vikhrs

You can only launch in pairs if you are in salvo mode (LCtrl-V). Otherwise, once your first Vikhr hits, you must turn OFF your laser before you can fire again.

I tend to switch laser off and on between launches.. can launch immediately this way

[Shaman]

High power laser range/designator overheats when kept continuously on (so especially during continuous guidance). It needs to cool off or else it will burn out sooner, it cool of rate depends on outside temperature, altitude, airspeed afir and how long it was operating since it was switched on.

I believe it was somewhere in the manual since Su-25T first release in FC1. Correct me if I am wrong.

There is a manual. Two manuals actually.

 

It's covered in the LOMAC FC3 manual.

 

It's also covered in the Su-25/25T manual for DCS World (which is mostly recycled content from the LOMAC manual, but with a few extras, and none of the junk related to A-10s, Mig-29s, F-15Cs, Su-27/33s).

 

These are PDF files that are included in a DCS World install, though I forget where exactly in the file structure their default pathname is.

 

Detailed instructions are in the manual, the other option is to cycle the laser on and off.

 

Though I seem to remember sometimes doing 2 Vikhrs in one pass without cycling the laser. Don't remember how I did it though. Maybe it was a seven or eight second pass.

 

In any case the issue is the weapons control computer simulation, not the laser thermodynamics simulation. Starting at about 20 km from target you won't have time to overheat the laser in a single pass before you overfly the target and loose designation due to the gimbal limits of the Shkval's camera system.

i like to have the vikhr in permanent salvo mode, as it allows you to launch 1 or 2 missiles based on trigger-pull duration. but as others said, when switching targets you need to manually reset the laser.
