One of the most impressive anti-submarine "Confusion" schemes (confuses me anyway) applied to "HANCOCK" on commision, photo is Aug. 1944 en route to Pearl Harbour with Air Group 7 aboard; this is Measure 32/3A also authorised for "INTREPID" and "FRANKLIN". Before her "horseshoe" tail symbols were marked on (SR-2E ordered 21-6-44 but effective from 7-10-44), tail numbers only carried as on her Helldivers here.
By 26 Feb. 1945 "HANCOCK" was in the much simpler Measure 12 (C-S19-7/631).
