LGBs and the TGP - Firing the laser after or before pickle?

Hi All,

Pretty straightforward question, I noticed that a few LGBs I dropped yesterday during a late night sortie were only hitting their mark when I fired the laser from the TGP after pickling/release.

I noticed if I’d fired the laser prior to pickle/release, the LGBs would just fall to the ground and miss the target

Is this intense behaviour or am I missing something?

Cheers

It should work either way, so most probably a bug.

However, firing the laser right from the drop might sometimes cause the bomb not to have enough energy to reach the target, especially if dropping from very high altitudes, like 20 000ft or higher. To my knowledge it seems to be best to start lasing 10-12 seconds before impact.

I usually stick to what works in the A-10: lase ~10 secs prior to impact.

Hi, so the delivery of the bomb could either be done through Auto or CCIP mode (or manual), the only thing is that you basically deliver the bombs as accurate as possible. The laser is for the terminal part of the flight and as stated above, about 10 to 15 seconds before impact.

The reason for this is that the guidance of the bomb is full deflection only which means that it will sort of bounce down a laser corridor to the target. If the guidance starts to early the bomb might go out of energy to reach the target and fall short.

So, drop’em as accurately as possible, do a left/right 45deg turn or so to make sure the view of the pod is clear, turn on the laser 10-15 sec prior to impact. The time to impact is in the hud TTI.

Good luck!

Ahh that makes a lot of sense, thanks! Do you know if we’ll be getting a TTI notification for JDAMs at all?

Is there currently a bug with the LGBs when using the TGP? I've tried a few times just now and only 1 out of about 5 LGBs hit their intended target, all the rest just over shot!

Anyone experiencing the same?

Yes, there is a known bug in regards to higher altitude drops. I am not sure where it starts off in terms of height though. You can swap to CCIP a bit early and release or fly lower (during practice). You can tell it’s going to go long if you haven’t hit the release point yet, but notice the TGP is nearly looking straight down (in which case, don’t release and make another pass).
