Numbers for some indicative rounds:



As for BZT being superior because it will 'pass right through', that is irrelevant ~ the lateral spread is lower than for a FAP round, and that will itself commonly exit the majority of fragments through and through. Retaining a single 'fragment' is not conducive to superior SSKP, though it may destroy rather than damage a critical component that *is* struck.

With good shot placement, any of these rounds can kill an aircraft with a single hit... the difference is the range of vulnerable components (eg 57mm *can* cause a general structural failure, while 14.5mm is relatively more likely to damage a critical component within the structure).

The available 'critical' list increases with warhead size, and also the permissible 'miss distance' within (or in proximity to) the structure. When the round doesn't ricochet (possible with very oblique impacts) and the fuse functions correctly (it may fuse externally on impact (halving (or more) the effect of exlosives), or may pass through the aircraft before fusing (ADEN rounds often had this problem when fired at fighters) leaving little more than a slightly over calibre hole in many cases.

I don't suggest that you model each 'wrinkle' of lethality, but considering all hits 'kills' from a .184kg 10% warhead is optimistic in the extreme.
