A two-dimensional thrust vectoring exhaust nozzle for a gas turbine engine, the nozzle comprising: a static structure having first and second laterally spaced apart sidewalls, each of the sidewalls having an inner surface defining lateral exhaust boundaries in the nozzle; upper and lower movable flap assemblies, each flap assembly including a vectoring flap extending between the first and second sidewalls, the vectoring flap connected solely to a first shaft having ends which protrude into the sidewalls through pivot shaft holes in pivot members rotatably mounted in the sidewalls, the pivot shaft hole of each pivot member eccentric to the center of rotation thereof, each vectoring flap fixedly secured to the first shaft therein to prevent relative movement therebetween, and means for directing exhaust gas exteriorly of each vectoring flap; and, means for selectively positioning the vectoring flaps.
