If the pictures on the Daily Mail website are legit, and that's an S-70 variant, it's a heavily modified S-70. Appears to be some kind of fairing at the tail, a 5 blade tail rotor, with a fairing over the tail rotor hub. The horizontal stabilators are canted backwards, and there's no rivets visible. I suspect the USG will be making every attempt to get all those pieces back before the Chinese show up.
