Ok, 40 yards is the minimum safe arming distance for the weapons fuse in Airburst mode. This is the minimum distance the shell its self has to move before going boom.

You roll to hit like normal with the +4 for targeting an area rather then a point target. When it goes off you can choose if it attacks in a forward (anti-air mode) or downward direction (anti-ground mode). You ignore the shells crushing explosive damage, it's assumed that it goes off far enough away that the blast doesn't matter, and instead just roll to see if anything is hit by the fragments as normal.

Example: A TL9 Viper 64mm missile armed with a 64mm HE warhead doing 8d×2 cr ex [3d] is fired at an incoming attack VTOL that is 130 yards away in air-burst mode. The missile has a effective skill of 17, base skill of 13 with +4 for being in air-burst mode, and with a roll of 12 hits. The missiles 8d×2 cr ex damage is ignored and instead attacked only by its fragmentation damage of [3d]. This is against a base skill of 15 modified by range, since this is a direct hit now range modifiers apply. Another 12 is rolled which is a MOS of 3, that means that the VTOL is hit with two fragments. 3d is rolled twice, doing 15 and 11 points of cutting damage respectively.

Unfortunately, as far as I can tell RAW has not answer for this one but I would rule that the target gets auto hit by a fragment for 3× normal damage as for an internal explosion to represent all the fragments going off inside the target. I would then roll to see if any additional fragments hit and give each extra one that does the same 3×.

As for the ripping out question, I'm not sure I understand the context. Some clarification would help.

for example. 25mm HE rounds set for proximity would blow for 4d cr ex damage and 1d+1 fragmentation. I assume that means for about 7 yard cone of possible shrapnal hits.unless fired from an airburt.

Ignore the cone reference, it's just "fluff" and has no game effect. Just treat the fragments as normal.

By RAW, no, but I would double the warheads cost for a hyberdense warhead and give the fragments an (5) AD.

See my above reply. I wold like to see an office ruling on this as well.
