This is in Awesome Mechas Why? I mean, granted, it is a pretty badass warscene, but where are the Awesome Mechas? Am I missing something here?

Look like Macross mixed in with some Ace Combat 6.

More like a sequel to Ace Combat 3.

'Mecha' doesn't apply exclusively to robots.

The red planes design almost similar to FA-2 Fawn II from the anime Sentou Yousei Yukikaze (Battle Fairy Yukikaze). Almost.
