My company produced these things--13 of them as I recall. As is typical with most such programs, there were many speedbumps along the way but eventually our aircraft division guys got it all under control and delivered an excellent weapon system. I'm semi-retired now, and I don't know whether the Air Force ever ordered any more of them.
I'm not sure how many the AF eventually received, but 13 seems too few, by a lot. They get a LOT of use these days....
I can only imagine the stress that 105 puts on the airframe when they fire it.
