RAM, -lynx-, and others...
I know this sorta defies conventional thinking...and I know you feel pretty sure of your positions...just as I once did as a new F-4 student sitting in my A2G class. I can still remember it...
"Well, look at it this way", I asked the instructor. "Let's say I'm in a helicopter, and I'm hovering right over the target at 5000'....the wind varies from different directions and velocities between me and the target. Do you mean to stand there and tell me that those winds aren't going to affect the bomb in its fall?"
Then I sat back with a smug expression on my face, thinking I had belled the cat.
"That's right, worm. That's exactly what I'm telling you.", replied the instructor.
And then he proceeded to explain about such things as fineness ratio and other stuff that I can't remember anymore (this was before many of you were born).
Later on, when I was a Fighter Weapons School instructor, I had the same question every so often. What it boiled down to was that a typical bomb is a very small but large mass object, and as such, given the relatively short time of fall, is very resistant to having its velocity vector affected by changes in the air mass through which it is falling.
Now, under extreme wind shear conditions, it is probable that the weapon's ballistics might undergo a deviation from the original velocity vector...but the magnitude would be relatively small and of only academic interest. Operationally, it would be of no significance.
