Re late 1944 the two ships were virtually identical except for two items, the Missouri wore a measure 32 dazzle camo scheme where Wisconsin wore a graded measure 22 scheme. Missouri mounted a round, parabolic air search radar on her foremast (SK-2) whereas Wisconsin mounted the older, rectangular SK-1 on her foremast. There may have been a few other miniscule changes that i can't recall. In 1945 both ships wore the Ms 22 graded camo scheme. In mid 1945 the Wisconsin had her mainmast heightened and shipped an additional air search radar, a smaller rectangular set called I think an SC-2. There also may have been some changes to the floatplanes. Initially both ships carried Kingfishers but before the war was over they may have been swapped for Seahawks.
