1. A turbine assembly for use with a gas turbine engine, the turbine assembly comprising
a turbine case arranged circumferentially around an axis,
a vane assembly arranged circumferentially at least partway around the axis and arranged radially inwardly of the turbine case, the vane assembly including a first vane and an outer platform arranged on a radially outer end of the first vane, the outer platform including a first anti-rotation protrusion extending radially outwardly away from a radially outwardly-facing surface of the outer platform, and
a locating plate arranged circumferentially at least partway around the axis and coupled with the turbine case radially outward of the vane assembly, the locating plate including a main wall, a first anti-rotation extension extending radially inwardly away from an aft end of the main wall, and a second anti-rotation extension extending radially inwardly away from the aft end of the main wall and circumferentially spaced apart from the first anti-rotation extension,
wherein the first anti-rotation protrusion of the vane assembly is arranged to engage with one of the first anti-rotation extension and the second anti-rotation extension of the locating plate so as to block circumferential movement of the vane assembly relative to the locating plate.
