An exhaust nozzle for a gas turbine engine includes converging and diverging nozzles joined together at a throat and attached to a frame. An injection slot is disposed at the throat in flow communication with a transition duct for channeling injection air therethrough as controlled by an injection valve for fluidically varying throat area for exhaust gases discharged through the exhaust nozzle.
