F117 precision strike how to (Im pulling my hair out)

[PSYKOnz]

Hi there

 

I'm trying to get the f117 to do a precision strike but for the life of me I can't get it to work

 

here's the mission plan

 

F117 waiting in parking, trigger makes it take off, fly through a few waypoints then attacks a tv tower thats next to an airbase

 

as it stands the F117 takes off, flies the waypoints but waves off and RTBs instead of hitting the IP and going in to bomb the tower

 

how the heck do I get it to work?

[Sedlo]

I think what's happening in your scenario is the F-117 is detecting a threat and aborting instead of completing the mission.

 

Perhaps try this:

 

Click on your flight in the Mission editor.

 

Under advance waypoint actions click "add".

 

Under "Type" select "set option" and select Action>"Reaction to Threat".

 

Select under "Reaction to Threat" no reaction or passive only.

 

This may work out for you.

[PSYKOnz]

Tried that still, no joy, brekes off in the same location every time, halfway between a waypoint and the IP

[Emmy]

How far from IP to Target?

[PSYKOnz]

same distance id gives any bomber, is there a minimum?

 

EDIT:

 

I've moved the IP way back, now it hits it but immediately turns for home rather than flying the attack approach

 

in the IP waypoint (waypoint 2) I have:

 

Perform task

Bombing

Weapon - Guided Bombs

REL QTY - All

ATTACK QTY - 1

Group attack - no

Direction - N/A

Altitude - N/A

Divebomb - no

 

the little triangle is on the comms tower I want to go boom

 

I also have

ROE = Weapons Free

REACTION TO THREAT = NO REACTION

RTB ON BINGO = Off

 

its carrying 2x GBU27

8466ib of plane juice

 

the Route length is: 191 nm or 21 minutes

 

the target is the structure Comms tower M and is Russian

 

I'm so confused here

 

do I need to make a trigger or something that makes it "attack group" or something?

i added in another waypoint, thats past the target so it now overflies the target (finally) but it's still not dropping its payload on it, the target is right under its flight path

[Emmy]

What kind of defenses are around the target?

[PSYKOnz]

none, it's on an airbase on its own.

[Emmy]

Weird...

 

I'm playing with an F-117 in the NTTR and with a "BOMBING" waypoint to target distance of 10nm (20,000' @ 350kts) it's putting both bombs on the hangar I have targeted at Groom Lake every time.

 

I even added an SA-11 at the Farms up at Rachel and the F-117 carried out a successful attack.

 

 

Do you have it set for "Pinpoint Strike" as its base directive?

[PSYKOnz]

correct, its task is "pinpoint strike"

 

at this stage, I have it flying directly overhead and still not engaging

[Emmy]

I'm afraid you'll have to wait for a "bigger hammer" to come along because I'm stumped...

 

Sorry...

 

 

Just out of curiosity, what's the assigned altitude and airspeed for the attack?

[PSYKOnz]

all good, thanks for your help :)

 

could it be the type of target it is?

[Emmy]

I don't think that should matter for "BOMBING"

 

The only other thing I'd try is maybe "BOMB MAP OBJECT"

 

Maybe...?

[PSYKOnz]

worth a shot

 

EDIT:

Nope still nothing

Here's hoping a better wizard comes along...

 

Good Luck!

[PSYKOnz]

yea, fingers crossed, thanks for all your help though!

Hi,

 

Post the mission here, so we can take a look.

 

Maybe if we see the mission we can help.

[Grimes]

If it is a basic mission with not a lot going on and the F-117 fails to attack, please post it. I've seen the behavior before in trying to debug a friends mission. It was some weird combination of F-117 + LGBs where the AI would generally not go through with an attack and I couldn't figure out why. Ultimately my solution was to modify the payloads by giving it JDAMs and it was able to attack without issue. Probably need to revisit the behavior.

[PSYKOnz]

now balled

 

OK, so I have some progress and also not...

 

so in the interest of a clean slate I deleted the f117 and re did it all to make sure I stuck it down with a flying start and set up the waypoints as before, everything went well, I was able to get it to attack the target, it was quite satisfying to see it finally drop and blow the tower up

 

I ran it through 5 times every time it worked

 

so feeling pretty chuffed I went and set the f117 to start uncontrolled on the ramp,

 

set everything back up all the triggers and the like

 

got in the game, fired the trigger via the radio command and sat back to watch what I thought was a victory lap.

 

however, it wasn't, I'm right back where I started.

 

it seems that the issue lies somewhere in the uncontrolled start and or the trigger

 

 

here is the mission.

please bear in mind that this is a training mission, there is a lot going on, it is designed for me and my mates to be able to train on the fly and change things up where ever

everything is at Kutaisi, the f117 (labelled b-117) is set up exactly how it needs to be for the mission

 

the patriot sites are just there to deal with the intercepters, they will go away once this works

 

again the only thing I changed between it working and it not working is it being started via a radio trigger rather than starting in the air near waypoint 1

 

I'm at my wit's end. not sure why when it's started like that that there is an issue but there is. who knows. I really hope you are able to help me

 

EDIT:

The other thing i did was to start in an aircraft as well, during the first tests that worked I ran it is a spectator

[PSYKOnz]

any progress?

 

everything else works fine except for this bit hahaha

 

 

 

here's a quick video of what happens, as you can see it carries on toward waypoint 1 and as soon as it hits waypoint 2 (the IP) it just turns around and buggers off home, completely ignores waypoint 3 altogether and doesn't even open its doors.

 

 

 

 

here is proof that it was working, again, the only difference is that in this one it starts in the air about 1 or 2 minutes away from waypoint 1 whereas in the one that doesn't work it is taking off from Kutaisi after a radio start command. it's the same aircraft. just different start

Hi,

 

I’ve tried your mission. It looks like a bug with the F-117. If you change the plane for another aircraft the bomb is released normally.

 

My advice for you is to try another bomber until they fix it. I’m sorry!

Edited September 9, 2019 by Bruce_D

[PSYKOnz]

hey thanks a ton! I can work with that!

 

let's hope the ED boys see this and fix it sometime :)

[PSYKOnz]

yup, here it is, confirmed...

 

swapped the F-117 to the F-4 and just like that everything works!

 

 

just a few more things to tidy up then ill post it up in the user files

Didn't get a chance to test it properly until now. Its not a bug, its the fuel. Why does it work if spawned closer or with different AI types? Its because the AI is deciding to abort the attack due to low fuel state.

 

I modified the mission, deleted most things other than the F-117, if anything so I can advance time without bogging down. I did add another F117 flight and a script that runs telling me what the fuel state of each aircraft is. In the screenshot the right aircraft is yours, the left one is mine. The main difference between the two is that I set mine to go slower and gave it a higher altitude to fly at. At that point, while there is almost 40km distance between the two, the rear aircraft has nearly 25% more fuel and more critically is well above 50% fuel usage when it gets assigned the target. In the end the original aircraft lands with 10% fuel remaining while the alternative lands with a little over 34% fuel, approx 10 minutes later, and has bombed the target while flying a bit further overall.

 

Bear in mind that the 50% fuel usage isn't a hard number. I changed your F-117 to an F-15E and gave it approx the same fuel weight that the F-117 carries and it just kept on attacking. Had to keep lowering its fuel to get it to exhibit the same behavior as the F-117, which occurred around 30% internal fuel with no bags. So the F-15E could have about 1322 fewer lbs of fuel and still engage. Granted it also shows a big difference as far as internal fuel goes where teh F-15E has about 2.5x the internal fuel of an F-117. At any rate there is likely an engine thrust, burn rate, and distance to RTB calculation going on to make the decision to RTB.

Interesting! In the version I did of this before I deleted the f117 and re did the whole thing I told it not to rtb on bingo and a few others and it still didn’t drop the bomb. Come to think of it that was the version that made it to waypoint 3! But it still didn’t drop the bomb on the target

 

That being said it makes complete sense, thank you so much for running such a throughout test for me mate! I really appreciate it.
