My dad-in-law served on the Wakefield, and later on the Callaway. From the stories he told me, the high number of friendly fire casualties in 1945 were inflicted by the proximity fuses on the a/a guns.. He claimed it was so thick, the ships were all "rained on", but they were willing to take the risk as it stopped the kamikazes.
