Insurgent warfare isn't something new. As noted, all aircraft are at risk for it.
Killface:
the article, on page two, suggests a recompete while ODT & E are still underway. I am not sure the author actually understands how acquisition works. There are actually rules and laws that Congress gets very upset to see broken ... most of the time.
I don't disagree with the author's frustration on the program bloat.
He's not unique in his perspective there.
I don't understand how that article is toxic.
