By the way, this is article, you should read up a bit:

And if your pretense was even true, why the hell are we using missiles in combat that have been OBSOLETE for 40 years? Are we trying to get our men shot down, or captured? We were damn lucky the Russians didn’t test their S-400 after that miss.
We use them because they are cheap and plentiful.
They are designed for close-in dogfights.
If the first shot is “diverted”, take another shot. It’s not unlike guns.
