A thrust vectoring gas turbine exhaust nozzle is provided with cooperating variable internal coverging-diverging flaps to provide nozzle flow path area control. A vertical take-off and landing capability is obtained by deployment of a rotating bonnet-type deflector which diverts the exhaust stream downward around one side of the exhaust nozzle. Actuating means are provided to rotate the nozzle throat simultaneously with deflector rotation to produce efficient turning of the exhaust stream in the lift mode. The actuation means also simultaneously controls the nozzle flow path area and external exhaust expansion in the cruise mode.
