Version: 2.5.6.49314 (also tested with 49718 and still exists)
TLDR:
CBU-99 is not bursting at 1500ft AGL with MFUZ=VT. It burst approx. 1.2secs after reaching the 1500ft AGL (at actually 670ft).
Detailed:
The CBU-99 is configured with MFUZ=VT; EFUZ=OFF; HT=1500.
Released at 7500ft, 540 IAS and 33° dive angle
The bomb flew multiple secs until reaching 1500ft, so it should be armed already.
The burst occured at ~670ft MSL (only 33ft ele at this place), which should be approx. 1.2s after reaching 1500ft AGL regarding the dive angle and speed. Additional information: In the Tacview replay i see a direct distance between the cbu-99 and the target of approx 1500ft as it bursts (could be a coincidence or maybe there is a bug that the distance is used instead of the actual height?)
As a result of this late activation i think the bomb is very inaccurate (ccip Pipper calculates with 1500ft???) -> Would be very interesting to have some technical detail here
Manual says on page 135 that it only arms 1.2 after release:
"HT Option. For the Early Access release, the Mk-20, CBU-99, and CBU-100 canister weapons default to use FMU-140 fuses. This is a fixed-setting fuse with an arming time of 1.2 seconds after release."
This behaviour is also researched and described by other users in this thread: https://forums.eagle.ru/showthread.php?t=217264&page=5
I would expect that the cbu-99 will burst at exactly 1500ft AGL once armed (1.2s after release). Or do i understand the expected behaviour completly wrong and this is the right behaviour?
I currently can only use this type of weapon to hit sth. with the PRI MFUZ Setting.. But maybe i am just too stupid to understand the CBU
Btw.: The manual is also wrong regarding the efuze settings which where already changed to efuze=off. It currently says on page 135 we have to put efuze to INST. But thats not the point in this thread here..
