AGM-154A JSOW - burst altitude?
-
Been using these a lot to great effect but one thing I notice is, when watching the ingress (SHFT-7) they always seem to fly into the ground regardless of my altitude setting. The spread of bomblets seems to work fine, it’s just the visual, maybe an optical illusion and they are popping open at 2000’ and I just can’t see it? Haven’t watched a CBU in a while but I seem to remember them opening, then the spray of havoc rains down…

AFAIK there is no visual effect for CBU burst
So they spread, but you don’t see it and the bomb behave just like a regular General purpose.
The effect on explosion is different with a larger effect radius -
What happens with a RL JSOW A is that once it disperses the airframe just sort of flies off to wherever it goes, not really guiding due to the change in CG…I forget if it tumbles or not, but probably does. So if you are watching you would always see the carcass hitting the dirt somewhere.
I guess what’s missing are the bomblet impacts? That’s a bummer…

Actually the intact JSOW goes right to the target, hits the ground, then you do see multiple bomblet/target explosions. It’s fine, just wanted to be sure I was set the burst alt correctly…

That’s not what happens in RL - it sort of goes past the target point itself…or falls short, I can’t recall. But once the payload is gone it goes pretty stupid…so to be realistic I suppose it should proceed on a ballistic path to a random impact point that isn’t the actual target point. As I recall it goes nose heavy, so I think it should fall short.
EDIT: my bad, looks like it goes tail heavy…

I have noticed the same. There is nothing wrong with what you are doing. I believe that I can hear the JSOW bursting open (some seconds before visual impact), have you noticed that?

Thanks Stevie. Watching that I wonder if it’s weight re-distribution or the effect of the bomblet panel cover being blown off or the aero change of having no bottom (or both) causing the “lifting” of the nose but it’s something that I doubt can be changed in BMS and in reality, not important just for eye-candy. As long as it operates properly (which it does) for the correct result i’m good…

Not sure, I’ll try and Fraps record the next drop so I can better listen for it! That and watch some CBU’s also as I have it in my head they do pop then dump…

On topic….
The viper doesn’t carry the C (penetrator) or it’s just not modeled?

Honestly, I think it’s a bit of all of the above…but mostly that the shift in CG post-dispense takes the airfame out of the bounds of autopilot control authority. Should be noted that the control force on a conventional tailed airplane stab is in the down direction - so what it looks like in this video is that the autopilot simply can’t put the nose down. It’s also possible that the autopilot destroys itself at dispense…don’t really know about that. And I’m not even certain that it does what you see in this video every time. In any event, the airframe goes to junk post dispense.
