First, for IJN side; I have been able to get A5M, A6M2-21, and B5N2 to spawn a flight of 4 and take off ok.

For U.S. side, I've been able to spawn a flight of 4 F2-A2 buffalos and they take off in pairs even clipping through the island superstructure. But, a group of 4 devastators will not launch except for plane 1. I even tried a different CV, shifting from SARA to LEX.

I'm sure it is a user problem vice IL-2.

Here are the files. It's just a simple set of tests for launching AI from CV, assigning fighters to escort bombers, then landing them back on the CV, vice a well thought out mission.

As a test, I also tried placing TBM-3's on a generic IJN CV and they won't launch from it either regardless of 1, 2, 3 or 4 planes in the flight.

I tested the mission. The problem seems to be with the TBD-1. I tried using other 4-plane flights and they all took off fine (even the TBM-3). I tried the original mission in 4.11.1 and it worked fine.

I would say there may be some kind of bug with the TBD-1 in 4.12. It should be reported.

*BTW, when you create landing waypoints on a carrier, don't forget to 'Set' it to the carrier, like you do with the takeoff. Yours were not done correctly.

Aviar,
Thank you for looking at this, and for the tip on setting the landing carrier. I never considered that point, and you're right the planes land on either carrier within the home base circle.

So I did some more testing and did eventually get the TBD-1 to launch 4 AI from the flight deck.

1st). U.S. CV Saratoga, I noticed that if the ship is within range of an enemy with her main guns, the guns traverse over the flight deck. I had 4 AI F4F-3's take off and plane 1 clips the forward gun mount destroying both the first plane and the gun. The 3rd plane to takeoff also hits the destroyed gun and flips into the air and crashes. Is it possible that the TBD-s sensed an interference with the gun and refused to launch plane 2, thus holding up plane 3 and 4 ?

2nd). I placed the generic CV with 4 TBD-1, 40% fuel, and a torpedo. Alongside it I put the IJN shokaku (making her same side) again with 4 TBD-1, 40% fuel, and a torpedo. On both ships the TBD-1's take off ok.

So it may well be user error as I suspected, Although I will have to keep the Saratoga farther away from enemy ships as she has a long range with her main guns.

You're 100% sure you got all 4 TBD-1's to take off? I couldn't get them to take off no matter what I tried. Can you post the mission where you got this to work?

Very sure, all 4 took off. And I stated the wrong name for the CV with the big turrets, it is LEX vice SARA. Sorry for that error.

Anyway, below files you will see two sets of 4 AI TBD-1's take off from parallel CV's. If you sub the LEX for the SARA you will see them collide with the forward gun turret on take off.

Maybe you posted the wrong mission? First of all, there is only one flight of 4 AI TBD-1's taking off (from the Saratoga). There are none on the Lexington. You said that "...two sets of 4 AI TBD-1's take off from parallel CV's."

On top of that, the TBD-1's never take off at all. You have them spawning in at 4 minutes. They just sit there and none of them take off.

I ran the mission through the FMB and that's the results I got (TBD-1's never take off).

In the test mission I posted, the two parallel CV are on the IJN side, Northern most home base. It was a test after all to see if I could get TBD's to take off. One CV is IJN, the other U.S. both on blue side.

Here are screen shots of two flights of 4 TBD-1 taking off from Generic U.S. CV.
- Carrier speed 33
- Fuel 40% with torpedo
(sorry if images are large)

1). Two flights of 4 spawn on deck at same time.


2). Lead flight 1 takes off


3). 2nd flight 1 takes off


4). 3rd flight 1 takes off


5). 4th flight 1 takes off


6). 1st flight 2 takes off


7). 2nd flight 2 takes off


3rd flight 2 takes off


9) 4th flight 2 takes off


As you can imagine, I was thrilled to bits when I was able to make this happen. I may have to expand my experiments on this and see how many flights will spawn and launch.

Every day I learn something about IL-2. Such an epic game!

Post the mission, I didn't have problems in my mission.

It's an event that occurs on virtually every mission when there are enough aircraft in the mission. Sometimes entire formations are eventually wiped out, just by collisions other over the course of the mission.

Some problems are result of new formation option in mission. Original code is somewhat strange but it sort of worked. In DCG, I suppose, there is a lot of situation when flights are attached to each other. In old patches you could have something like this happen.

a=first flight , b= second flight
1a  
        
            2a
                
                        3a
                               1b                        
                                      2b 4a

Above situation is obviously wrong but it works and there is no collision .
In 4.12 it happens often that 4a and 1b collide because wrong group formation is selected. It should be better in 4.12.1 but how many changes in formation code will be necessary is yet to be seen.

If you say so, but that's not the mission I downloaded. See the screenshot. There are no red flights coming from where you said (...the two parallel CV are on the IJN side, Northern most home base.) Plus when I test the mission there are no carriers with 8 TBD-1's spawning on them.

There are 2 flights of TBD-1's in D2 but they start in the air.

Anyway, if you're happy then that's all that matters.
