Hmm
The 2 second delay is not the problem.
Its the
casing touching the scenery within those 2 seconds that disarms the bomb that's the problem and not realistic.
The bombs velocity should decide its arming if its skipped or bounced into the target ship or tank the arming vane should be the deciding factor.
If this route is being taken for mud movers/bomber/Jabo to make it realistic etc etc, then start giving the fighters realistic mg/cannon jamming in the wings under
G load.
We will soon see some reaction for that one
