Operation Eldorado Canyon, 1986 (Updated January 12, 2025)

Post by Kushan04 »

On the 5th of April 1986 terrorists detonated a bomb in a Berlin nightclub. The bomb killed 2 American soldiers and a Turkish woman and injured 229 others, 79 of whom were American.

In response, citing evidence that the government of Libya was responsible, US president Ronald Reagan ordered airstrikes against Libya on the night of April 14/15, codenamed OPERATION ELDORADO CANYON.
This is a complete remake of my original Operation Eldorado Canyon scenario. I incorporated a lot of changes based on Jim Rotramel's (One of the 48th TFW planners) new book on the raid. I've also taken the opportunity to expand and fix a number of issues I had with the original scenario. This includes completely redoing all of the Lua scripting. Full change log below.

Look forward to comments and critiques.

Release Candidate 10 (January 12, 2025):
• Standardized random weather function names.
• Added "Gameplay Notes" message when the scenario is first loaded. This message gives detailed information of all of the scenario mechanics & features. Can be replayed via the "Replay Gameplay Notes" special action.

Release Candidate 9 (December 20, 2024):
• Fixed global weather drift.
• Reduced weather variability chance.

Release Candidate 8 (December 19, 2024):
• Updated database to DB509.
• Added Political and Strategic Actions special action. Strike options, overflight requests, and deployment of additional aircraft have been split off from the scenario setup options. This will allow the player to review their forces before making decisions on their own forces. Actions related to setting up the Libyan side and scenario features remain on the scenario setup options menu.
• Added Custom Environment Zones regions. The area of operations has been divided into ten CEZs. Every hour weather will drift positively or negatively based on the current conditions within the zone. Real world average weather conditions are used as the baseline where applicable.
• Added new scenario setup option to use historical or random starting weather conditions.
• Fixed starting aircraft status. This will allow players to issue manual orders to aircraft before they are ready for takeoff.
• Adjusted frequency of weather changes, weather will now update every hour.
• Aircraft will no longer perform FENCE checks after entering an area 5nm from their objective.
• Added missing units to USA Unit Destroyed event.

Release Candidate 7 (October 6, 2024): This version requires the B1405 Public Beta patch or newer.
• Various updates & fixes to Lua weather functions.
• Changed frequency of weather changes. Weather will be randomized at the start and then randomly drift positively or negatively every 3 hours starting at 1800Z. Previously weather change would occur every 6 hours.

Release Candidate 6 (September 22, 2024): This version requires the B1405 Public Beta patch or newer.
• Updated CSAR scripts. Multiple downed pilots units can be added when a player aircraft is destroyed. The number of downed pilots is based on the destroyed units database crew value. Each crew member has separate survival roll, the number of crew represents the maximum number possible survivors per aircraft.
• Downed pilots within Libya territory have a random chance of being captured. This currently only affects downed pilots on land. Downed pilots in the water are not affected.
• Adjusted point gain and loss for downed pilots that are rescued and captured. Gain more points for pilots rescued. Point loss for captured down pilots is based on the number of aircraft lost. 250 points loss for 5 or less aircraft destroyed, 500 point loss for over 5 aircraft.

Release Candidate 5 (August 25, 2024): This version requires the B1405 Public Beta patch or newer.
• Updated database to DB507.
• Updated aircraft DBIDs and loadouts.
Added new Strike option: USN Only Strike. Most people think the USAF was included in the operation to give them a "piece of the pie" but that is not the case. The USN did not have enough aircraft to hit all the designated targets with the levels of force deemed necessary. Deploying another carrier to the Central Mediterranean or additional strike aircraft where considered but were not chosen. They would have either taken too long or potentially have provided additional strategic warning to Libya. This option also enables specials actions to deploy additional A-6Es to the USS America and ready additional A-6Es that are normally set to maintenance. You have the option to change A-6E loadouts, but unavailable loadouts have been filtered out via lua. If you change loadouts, run the "Set Ready Time for USN Strike Aircraft" special action before hitting play.

• Added new scenario realism setting: Take Off Fuel and Usage. Default: Aircraft will take off with full fuel. Default Command behavior. Historical: USAF aircraft will have fuel adjusted to estimated historical values after taking off. This should result in more accurate fuel usage. Unlimited: Aircraft will take off with full fuel. They will still use fuel but will be periodically refueled via in-game event. No tankers will be needed.

• Added new scenario realism setting: Enable System Checks. Turned on by default. This setting enables or disables the various aircraft system checks events.
Designer Note: The various system checks have always been in the scenario, this setting now allows you to turn them off.

Completely reworked Combat Search and Rescue (CSAR) functionality. Selecting units and executing a special action is no longer needed. Maneuver a rescue unit to within rescue parameters of a Downed Aircrew and recovery will happen automatically. There is an element of randomness to the recovery in order to simulate difficulties recovering the downed aircrew. Aircraft rescue parameters are within 1nm, at or below 75 AGL, and at or below 50 knots. Ship and Submarine rescue parameters are within 1nm, above -20 ASL, and at or below 6 knots.

Release Candidate 4 (May 1, 2024):
• Added Historical Events. Optional scenario setting. Historical events that may have raised the Libyan readiness. There are a few events you will receive an in game message regardless if this setting is turned on or not. In those cases the messages are generally the historical outcome, but have no effect on gameplay.
• Added Historical Messages. Optional scenario setting. In game messages that tell larger story of Eldorado Canyon. Have no effect on gameplay. For situations where there is a Historical Event message and a Historical Message, the Historical Message will appear 5 minutes after the Historical Event.
• Added additional Libyan readiness levels.
• Changed the F-111 abort chance to 30% (was 2%).
• Changed the A-6 abort chance to 5% (was 1%).
• Swapped DOBBY 33 and DOBBY 91. DOBBY 31 was the KC-135Q.
• Updated Messages PDF.
• Added Historical Messages PDF.

If you have installed a version prior to RC4 please remove any related files in your scenarios folder first. I have renamed all of the external html files; briefing, description, and events.

Release Candidate 3 (April 16, 2024):
• Added additional reference points to USAF strike force course.
• Adjusted F-111/F-117 ready times.
• Fixed USA aircraft lua error at scenario start. Coral Sea A-6s should now have their systems checked like the Americas. This will set units that fail the check to unavailable.
• Fixed spelling mistakes in the briefings.
• Added PDF's of mission briefings.

Release Candidate 2 (April 9, 2024):
• Reference points for the USAF strike forces course will be added at the scenario start. These are for player convenience and can be deleted if you wish to use your own. This is dependent on the overflight option chosen. When using "Historical" overflight the actual planned flightplan waypoints will be added. For the France and Spain overflight options I have chosen a course that I think makes sense.
• Added PDF of html messages. Briefings are not included at this time.

Release Candidate 1 (April 8, 2024):
• Updated database to DB504.
• Split Libyan air defenses into Western (Tripoli) and Eastern (Benghazi) sectors. Sides should have a delayed response if one side is attacked and the other is not.
• Redid all of the lua script.
• Implemented html dialog box for scenario setup. Added more scenario setup options. Can now select the chance to occur for most options. I.e. can choose the chance of overflight being granted, the chance Libya will respond to various strategic indicators, the chance Libya will scramble QRA, etc.
• Scenario description, briefing, and most in game messages are now external html. This was done to get the formatting of certain messages to look more accurate.
• Added USAF 67th Aerospace Rescue and Recovery Squadron to Naples IAP. Deployed historically but not used.
• Added EC-130E to Aviano AB. To be used for SAR support. Deployed historically but not used.
• Updated USAF ready times.
• Updated USN callsigns.
• Updated starting weather.

Extract all the files in the same folder.

In my case I have a folder for the scenarios posted in the forum. As this one comes with extra files I created a folder for it.

Code: Select all

\Scenarios\Forum\Operation Eldorado Canyon, 1986 RC1

And thanks Kushan for the dedication to this scenario :)

Will take a while, but definitely gonna enjoy this one, tnx for all the work!

You often read about this operation from the US side, the link below shows some reflection from the Russian/East German side:

Nikel is correct, they need to go into the same directory as the scenario file. I know it's not ideal but currently the game won't support standalone html files for messages in a sub-folder. The next release will also have all the messages in a single pdf, since they don't show in the message log.

Thanks for that. I've seen that before. Other then as as another source for the positions of the SAM sites and opinion of the Libyan's performance, there's not much accurate about what actually happened. It is an interesting read about what they think happened that night.

Posted a small update. For player convenience, reference points will now be created for the USAF strike forces course when the scenario is started. This will happen for each of the overflight options.

I've also added a PDF of the html messages.

Just downloaded RC3 and opened it up and ran it for a few seconds. All of the aircraft are airborne and none of the bases, including the carriers, have aircraft on them. Followed the usual procedures for downloading Community scenarios, so am scratching my head.

Save file attached. I'm running 1328.14

That's a game bug, not an issue with the scenario. Please report it, with the save, to the Tech Support forum.

I haven't seen that bug when using B1328.18.

Indeed, it happens in 1328.14 but not in 1328.18

Was fixed in 17. Not sure which of the fixes listed could be.

Posted RC4. This version adds two new scenario options, Historical Events and Historical Messages. While they sound similar they are different.

Historical Events are real events that may have raised the Libyan readiness level. Where appropriate you will receive an in game message. There are a few events you will receive an in game message regardless if this setting is turned on or not. In those cases the messages are generally the historical outcome, but have no effect on gameplay.

Historical Events tell the larger story of Eldorado Canyon. In cases where there are both a Historical Event message and a Historical Message, the Historical Message will appear 5 minutes after the Historical Event.

Hi Everyone. I'm working on a new update. It will be available when the next patch goes into open beta or releases. I've added a couple of new scenario features.

Combat Search and Rescue Overhaul: I've overhauled the CSAR lua scripts. You will no longer need to select units and then execute a special action. Now all you need to do is maneuver a rescue unit (helo, ship, submarine) to within rescue parameters of a "Downed Aircrew" and recovery will happen automatically. This should make it a more seamless experience. The rescue attempt action will fire every 1-5 minutes. I'm still working on the exact timing. I've built a little bit of randomness into the new script so survivor units are not picked up at the same time. Rescue units will only be able to rescue one survivor unit at a time. So far in my tests this has been much better then the current script. I plan to implement this into my Iran scenarios as well and possibly some others. Eventually I might look into actually adding a survivor unit as cargo to the rescuing unit.

Set Takeoff Fuel and Usage: One of the biggest inaccuracies with the current scenario is that aircraft in Command will always takeoff with full fuel. This was not the case with the USAF aircraft, especially the tankers from RAF Mildenhall. While this provides a significant safety margin, I've always wanted to find a way to make the fuel usage more accurate. With the new Air Base Status triggers I now have a way to do that. I've added a new scenario setup option for Takeoff Fuel and Usage. It has three available options: Command Default, Estimated Historical Takeoff Fuel, and Unlimited. The Estimated Historical Takeoff Fuel option only affects the USAF aircraft. I could set fuel for the USN aircraft but they start well within range so it's not going to make a difference. With the Unlimited option aircraft will still use fuel but will be refueled automatically via lua every X minutes.

USN Only Strike Option: Most people think the USAF was added to the raid to give them a piece of the pie. In reality they where used because the USN didn't have enough strike aircraft to hit all the targets with the required levels of force desired. Options like deploying additional A-6Es to the carriers already in the Med or another carrier where considered but either couldn't be done in time or would have been to much of a strategic indicator. This strike option is meant to showcase these issues, although I have added a special action to deploy an additional A-6E squadron. This option should be compatible with some of the existing scenario options (i.e. Historical Events).

There are some additional strike options I'm thinking about adding. The original planning for OEC (under the code name Prairie Fire, which was used for the operations in May 1986) envisioned a significantly smaller strike. Originally the USAF and USN where given the same three targets but after the initial briefings it was a agreed to split responsibilities, if possible. There's a couple of variations of these I could add but I'm not really sure if they'll be added now or not.

Just posted the update. Took a little longer than expected to workout some bugs.

In addition to the changes I posted above, I've added a new scenario setup option to enable/disable the various system check events. This version does require the B1405 public beta patch. Unfortunately as of B1405 there is a bug with external html files not displaying special messages. Please reference the Messages and Historical Event Messages pdfs for these messages in the mean time. These can be located in the documents folder included with the download.

As always I look forward to any comments.

If no major issues popup I'll give it the official v1.0 tag in a few weeks. Don't think there's much that could be added at this point. Someday I may implement the smaller strike options but for now I think it's time to put this one to bed for now and move onto my next scenario.

This bug should be fixed in the B1436 Beta release that came out today. Messages should be displaying correctly now.

New update posted. This fixes a couple of issues with the revised CSAR scripts ibn RC5 and expands the SAR functionality a little.
• Multiple downed pilots units can be added when a player aircraft is destroyed. The number of downed pilots is based on the destroyed units database crew value. Each crew member has separate survival roll, the number of crew represents the maximum number possible survivors per aircraft.
• Downed pilots within Libya territory have a random chance of being captured. This currently only affects downed pilots on land. Downed pilots in the water are not affected.
• Adjusted point gain and loss for downed pilots that are rescued and captured. Gain more points for pilots rescued. Point loss for captured down pilots is based on the number of aircraft lost. 250 points loss for 5 or less aircraft destroyed, 500 point loss for over 5 aircraft.

I've updated the code for weather drift. It should be a little more realistic now. I have some additional changes planned for this. I've added code for weather drift within Custom Environment Zones but it's not currently implemented in the scenario. The below image is roughly what I'm thinking for the CEZs. They won't have much (if any) direct effect on how the scenario plays out but I think they'll add a little more immersion.

Can we use the same custom overlays with this one as with the previous version?

Yes and no. The Aziziyah Barracks, Tripoli IAP, and Benina Airfield should still be accurate. The other two, Sidi Bilal and Benghazi Military Barracks, got moved in this version of the scenario due to being in the wrong location. The imports will work but they won't line up with the target.

I added custom environment zones for all of western Europe. I'd like some feedback on the visibility.

Option 1 - Each zone would have it's own color, see screenshot 1 below. I can probably make a menu to let the player determine the color of each zone. Unfortunately it doesn't look like the opacity can be changed via Lua so that would likely be set to 10-30%. 30% is what is shown in the screenshot.

Option 2 - Make the zone 100% transparent but the text would still be visible. Screenshot 2 below.

Option 3 - Scrap the whole idea until if/when we get a map display toggle for the CEZ visibility.
