I think this equation applies to that F15 in one of Clancy's novels (can't recall which one...and I think it's Clancy) that flies straight up to shoot out a Russian Recon-sat.
Well, a lot of military fighters can do that, but you're thinking of http://www.wpafb.af.mil/museum/space_flight/sf14.htm". It does actually exist (as do most technologies Clancy utilizes in his books), it just wasn't ever deployed (that we know of :uhh: ).

And yeah, that equation could be used along with the fact that at that attitude, Cd is constant because AoA is zero and engine performance varies with altitude, to calculate how high that F-15 could fly before its speed gets too low for control.

I think, though, that the F-15 did a "zoom climb" - started at like mach 2 and then pulled up, decelerating all the way, and never reaching an equilibrium between its engines and drag - exceeding the altitude it could have reached on vertical flight alone.
