A gas turbine engine augmentor radial fuel spray bar has a counterswirling spray bar heat shield. Two embodiments of the heat shield include one with a cambered airfoil cross-section and another with a twisted airfoil cross-section and may have varying or constant degree of camber or twist, respectively, along a radial length of the spray bar heat shield. The spray bar may have one or more spray bar fuel tubes within the heat shield, openings in the heat shield, and fuel holes in the tubes operable for injecting fuel through the openings. A gas turbine engine augmentor having a plurality of circumferentially spaced apart radial flameholders may incorporate a plurality of the augmentor radial fuel spray bars with one or more of the augmentor radial fuel spray bars circumferentially disposed between one or more circumferentially adjacent pairs of the radial flameholders.
