Shit-talking aside, though, Russia never claimed that the S-500 was actually done – I assume that they just yanked their prototype onto the battlefield because the S-400 wasn’t able to intercept ATACMS missiles either (which it’s supposed to be able to – the S-400 doesn’t have an excuse). We rolled out the Patriot when it was still in a prototype, half-baked stage in Iraq, too – just that it was all we had that might be able to intercept a ballistic missile, and we really needed the capability right then – and it didn’t fare well either.
So I suppose that the S-500 guys probably don’t necessarily deserve quite the ribbing that the S-400 guys do. They were probably put in kind of the same place that our Patriot guys were.
