I just had another test run. US vs Red March 2014. Spotter plane to light up enemy and then one by one level bombers (lots of armor and soft targets). Target don't have any AA (they didn't shoot back).
B-2
(before)
FAE x 8
FAE x 8
FAE x 8
FAE x 8
-> 4 x bombs to first hex, 2 x bombs to second hex, then it stopped.
(after)
FAE x 6
FAE x 6
FAE x 7
FAE x 7
After bomb run it seemed to have damage = 1 meaning it won't ever come back for another run.
B-1
500lb Bomb x 21
500lb Bomb x 21
500lb Bomb x 21
500lb Bomb x 21
-> 4 x bombs to first hex and then quit.
500lb Bomb x 20
500lb Bomb x 20
500lb Bomb x 20
500lb Bomb x 20
Damage 1 and 20 bombs were not used
B-52
2000lb Bomb x 6
2000lb Bomb x 6
2000lb Bomb x 6
-> 3 x bombs to first hex, 1 x bomb to second hex and quit.
2000lb Bomb x 4
2000lb Bomb x 5
2000lb Bomb x 5
Again, not very complete run (and of course damage = 1).
Tu-22M3 (Russian allies)
1000kg x 6
1000kg x 6
1000kg x 6
1000kg x 6
-> 4 x bombs to first hex, then quit.
1000kg x 5
1000kg x 5
1000kg x 5
1000kg x 5
Needless to say, damage = 1 and waste of money.
Su-24
500kg x 8
-> 1 bomb to first hex, 1 bomb to second hex, 1 bomb to third hex, 1 bomb to fourth hex and quit.
500kg x 4
This almost did it, reached 50% but it should have dropped four more bombs (to hexes 5th - 8th).
Su-24M
ZAB-500 FAE x4
RBK-500 CBU x4
ZAB-500 FAE x4
RBK-500 CBU x4
-> 2 bombs per hex (FAE + CBU) to 1st, 2nd, 3rd and 4th hexes, then 1 bomb (CBU) to 5th hex and 6th hex. Close! But no cigar.
ZAB-500 FAE x0
RBK-500 CBU x0
ZAB-500 FAE x4
RBK-500 CBU x2
Seems that slots 1 and 2 were emptied, slot 3 were not used at all and slot 4 activated late (5th and 6th hex). And of course damage = 1.
I suspect that this damage = 1 after bomb run is normal making only one strike per bomber. No problem. But then, why those bombers doesn't empty their bomb load at full? This is not random because in every game same happens. No AA fire present.
In earlier version if there was x8 bombs it bombed 8 hexes in row. The more slots with bombs, the more bombs per hex.
