The way the C-130J was first marketed in the United States was as a so-called commercial off-the-shelf piece of equipment. Because of that, the program bypassed the usual procurement rules that would have applied if it had been a major systems acquisition.
I'm going back a decade now, but as it turns out, the C-130J really wasn't commercial off the shelf. I was working with people in the U.S. Air Force at the time, who took the position, “We're just taking delivery of this thing. We don't have any requirement for it. There's no reason we have to go through the usual rules, because we're just taking delivery. Members of Congress are helping us afford it, so we don't have to deal with this piece of equipment in the way we would normally.”
But in fact, as the recent report by the Office of the Secretary of Defense, just last January points out--this is not me now--70% of the C-130J is developmental in nature. So even today, a decade after I first started to deal with the C-130J, there are still developmental issues.
