What kind of radar did HAIDA carry?

Originally, she had 271Q back by the emergency conning position but that was short range because it was sited low and was “wooded” (obstructed) by the forward superstructure – surface target at nine miles. In late 1944, the Type 293 “cheesecake” was added on foremast. Prior to her first Korean trip in 1953, the Sperry (solid antenna) was added to the foremast for surface search & navigation. Prior to her second Korean trip in 1954, the SPS6C (large lattice antenna) was added for air search.
