Well done and thanks.

[xxJohnxx]

Thanks! Especially the glare cover is interesting! :)

How you managed to get more wire to missile? Seems to be a bug.

[rrohde]

Nice! And thanks about the anti-glare shield tidbit! Wasn't aware of that. :)

[Kelevra9987]

That with Glareshield and extending the HOT3 range I allready knew but how did you get a collored Viviane Screen?

Yes, surely the missile shouldn't be steerable when you run out of wire and I thought wire length was part of the operational limit here? But then again I'm not an expert on wire-guided missiles.

[FishDoctor]

After reaching the limit of the wire the hot cuts of and continues flying unguided in a ballistic way. thats why it works :)

[Cibit]

Nice tips and nice music many thanks:)

[Lanius]

I just have rl experience of 9K111-1 Konkurs system. Least for it wire is the range of steerable missile. I guess it is same for HOT3. With konkurs you can also steer missile manually if there is too much IR jamming .

[Lanius]

In video it hit on tracked vehicle which was moving. Makes me wonder how well it is actually modelled.

And when missile receives steer commands from launcher with by wire. Missile constantly makes pitch yaw corrections it doesnt fly staight. And when wire is cut, last steer input is left and there aint no other input to correct flight path. It is pure luck if it hit on anything. Gyros just keep it flying straight from last attitude.

I actually use the Shkval Colour Mod for DCS 2.0 mate :thumbup:

Thank you:)

Obviously this is a bug. I hope you have reported it in the "bug" thread so the developers can fix this.

Lanius has a pretty good explanation about how the extended range is possible.:thumbup:

After the wire breaks the missle just continues on a ballistic trajectory and as the rocket motor will continue to burn after the wire breaks it's not implausible.

It would be nice to hear from a subject matter expert and the Devs though.

Does anybody know the exact range of the HOT 3s wire?

 

Since as the Stated max effective range is 4,300m the wire has to be slightly longer.

 

does anybody know exactly how much longer?.

 

50-100M? or more?

 

And also.

 

The missile has a top speed of about 864 km/h that translates to around 240 m/s.

 

We dont know the exact range to the targets at the time the missiles hit but lets say it was around 4700-4800 seeing as they had kept moving from his laze in the beginning that read 4900.

 

So if the wire was cut at around 4400 meters the missile would have traveled the rest of the way in less then two seconds.

 

So if we look at the first shot at the moving target its very possible that the missile read one of his last 2 adjustments just before the wire was cut and then continued that direction and that would also follow with the time scale

(since if the missile was traveling at the top speed of 240 m/s it would have been around 4300-4400 meters from the target 1,5-2 seconds before impact)

 

So will have to take more testing to see if its working as it should or if its a bug

(but from this video there is no real evidence against this being realistic)

 

Maby a Tac-View or something could be helpful in getting accurate info.

 

Or maby simply if you mark a target at range where the wire should have been cut (lets say 4500m+)

 

and have the missile fly over it and once it passes the target (Range marker) try to maneuver it.

 

If the missile can still be manually turned at a range that can be proven to be after the wire cut then its likely a bug.

Try it over a much longer distance and see if it works. Hopefully it was just because your targets were barely out of range.

[King_Hrothgar]

It works at up to about 8km, at which point the missile self destructs. Incidentally, the missile does not start losing speed after the rocket motor burns out, it holds a constant speed until impact or self destruct. I do not know if the missile can still be steered beyond 4.3km, but it can definitely hit a static target.

[Lanius]

I have to point out that during flight when missile is on wire, it makes constant corrections to keep ir flare back of the missile on middle of flight path related to the crosshair. And when wire is cut i will drift away from flight path depending what was last control input. So accuracy drops drastically when range increases . It could be a miss even flight time would be short as 2s.

[Lanius]

Dont mind the copilot

 

I made little drawing explain what i mean.

[Lanius]

It seems to working as i describe in picture. Hitting targets at after 6.8km seems to be random. I might move crosshair too fast , and sight loses track of the missile. I continue tests

[Lanius]

At range of 7500m i miss targets by 10m . Missile starts fly straight after rocket engine burns out . I dont have tacview .

[Lanius]

Okay. I found out you cant steer it 4 sec before rocket runs out.

[MBot]

Good drawing :) You are absolutley right.

 

The same thing should happen when the targeting sight descends behind cover and loses LOS to the missile, even with the wire still intact. Imediate loss of guidance and a deviation of the flight path according to the last steering command.
