Partial and uncoordinated launch of missiles in anti-ship strike mission

Post by meltingSnowdrift »

Procedure to reproduce
Run the attached scenario.
This scenario contains my attempt to create a minimal reproduction of the problem. Automatic detection was used to easily make sure that the player's side knows about the type of the target and therefore knows its missile defence value. As far as I could tell in other testing, the use of automatic detection does not alter the reproduction of the problem.

Expected behaviour and reasoning
The missile defence value of the target, according to the database viewer, is 16. The WRA, which I did not modify, says to launch a number of missiles equal to the target's missile defence value for most types of targets, including the type of this target. Its "shooters per target" setting says to "fire weapons from enough units to fill the salvo's weapon [quantity] requirement". Each aircraft group participating in the strike has 4 missiles. There being three groups, the total number of missiles carried in the strike is 12, which is less than 16. I therefore expect each aircraft group to launch all its missiles upon arriving at its launch point.

Actual behaviour
All aircraft groups take off and proceed to their launch points. However, only one group actually launches its 4 missiles. The other two groups wander around near their launch points, alternating in state between "engaged offensive" and "on plotted course". The members of these groups become quite separated from each other: for both groups, the leader became separated from the other group member by more than 50 nautical miles in my latest test.

This behaviour continues until the missiles (launched by the group that did launch) hit the target ship. If the ship does not immediately sink, the groups which did not originally launch (and which are now wandering) launch a total of 4 more missiles at the target. They then return to their wandering state. This repeats, with 4 missiles being launched each time, until the target is destroyed or the remaining aircraft groups run out of missiles.

My version of Command is 1307.14.

I think the way this problem manifests itself causes players to focus on the symptom, and not the cause. Its not about flight leader or only one flight firing. As you can see, in this modded scenario, all 12 AGMs fired as they should and the CF-18s are RTB after firing.

All I changed was the WRA for the AGMs to max fire weapons from all mission units on the salvo. I took defensive value completely out of the equation. My supposition is either the db defensive values are wrong or the translation of that value into salvo size is wrong. Unless I'm not understanding the defensive value in the db. I think this might manifest itself in several of the bug reports about how mission units fire salvoes.

ASuW strike is carried out by 12 x F/A-18E in 3 groups with total 24 AGM-158C and 12 x F-35C with total 24 HAWC
The F-35C will RTB before they release all their missiles

See this F-35C group has two HAWC left in their weapon bay.

AGM-158C
in some of the test run the F/A-18E didn't release all the missiles. like this one

but sometime the group with AGM-158C remaining on their wings will first RTB, then turn around , fire the rest of the AGM-158C, just like the screenshot below

In both two cases, the missiles were dispersed . the distance between the first one in the front to the one in the back can be as far as 50nm.

In all that, was there a save? I'd like to play around with the WRA.

edit...I see it in that first post.

I ran it six times at single flame. As you can see below, the first run through seemed to do exactly what was asked of it.

Of the other five runs, three did exactly the same. In two runs one AGM-158 stayed on and the F-35 and went back to base. It was the third run and fourth and the rest went with no issues. I think this is a separate issue from the OP.
