The VF-21 was mind-controlled, and the new plane in Frontier looks to be mind-controlled. At the end of the Macross Plus movie the VF-21 flies off into space somewhere.

Could it be those new guys found it, added their own technology or just advanced it a lot, and are using it as some kind of elite attack squad?

I don't think I'm too far off considering how many other references to previous series there are.
