 I have a question about the proposed powerplants for the YF-23.

    Will they be afterburning?  If so, are they equipped with some sort
of nozzle which can expand when the burner lights?  And what are the
differences/problems stemming from the use of a rectangular nozzle
opposed to a round one?  And how good are the IR suppression techniques
when the afterburner is being used?
