There's no way an F-18 can reach such a speed. In fact, a "clean" (no ordinance) F-18 can reach only Mach 1.8. With full ordinance load it is said to be barely supersonic at all.
In fact, there is actually only one fighter jet in the world to reach Mach 2.8, the Mig-31, and even it can only reach it at high alitude. And it's an interceptor with brick-like maneuvrability, completely unable to pull high-G maneuvres.
That makes Rainbow Dash even more awesome, probably.
