Your friend is correct.  Concorde *is* equipped with Afterburners, but
they're used only for brief periods (takeoff and transonic acceleration).

The use of Afterburners roughly DOUBLES the specific fuel consumption.
Concorde wouldn't have the range to cross the Atlantic if their use were
required for cruise.
