A lightweight exhaust nozzle/thrust reverser for a gas turbine engine comprises a flap-type exhaust nozzle with a thrust reverser door built into a cutout within each flap. The flaps may be hinged at their forward edges to the engine exhaust duct and may either be actuated or may float freely. Preferably, when the reverser doors are stowed they blend smoothly with the internal and external surfaces of the flaps. Actuation means deploys the doors such that they extend into the gas flow path and coact with each other to form a wall which blocks the axial flow of gas, and they simultaneously open the cutout within which they are disposed and redirect the exhaust gas through the cutouts in an upstream direction. In a preferred embodiment the flaps define the divergent portion of a convergent/divergent exhaust nozzle.
