There is no half-way to set the blast height

You have to install the FMU-140 fuse to get the RadAlt height of burst function. This is not a bug

Well, I admit that I haven't flown in a long time, is this something in a recent update? I remember that it used to be directly usable by default. Also AGM154A everything works fine。

I'll try again tomorrow，thank you

It's been close to a year since we have them I think?

The AGM-154A doesn't have fuzing options, so it works out of the box.

The CBU-99 defaults to the Mk 339 timer. The FMU-140 has to be manually picked during rearming on in the ME.

[Qazplm]

I found them, but the MK20 has only one fuse option - MK399Mode1, which can only be set at the time of installation, the drop of submunitions begins a few seconds after the drop, the altitude limit cannot be set, and it cannot be set while flying。

[Tholozor]

That is correct, the Mk 339 cannot be altered from the cockpit, the pilot can only select the primary or optional function timings. The FMU-140 also cannot be changed from the cockpit, changing the height function on the STORES page only changes release symbology (so ensure it matches what the bomb is set to). Use the CBU-99 to install the FMU-140.

Yep, close to a year and still no sufficient documentation. What little documentation we do have is user-created scattered on the forums or on some dude's paid-tier Patreon.

That one is for me I suppose. 99% of the info that I compiled regarding bomb fuzes are freely available. Not even a free membership needed.

But that doesn't mean there's no need for an official doc.
