In going through more of the 1941 camo documents that I have access to, I found something that explains why USS NEVADA and USS TENNESSEE have painted decks and most (or none) of the other battleships don't. See attached, note which battleships were included in these "painted decks aerial observation camo effectiveness" experiments.
The first letter dated 31 October 1941, had an attachment providing a "temporary" formula for mixing a paint to use in place of the new 20-B deck paint.
The second letter dated 12 November 1941, provides a revised list of ships involved in the experiment and that were to have painted decks. I don't know when their decks were painted, but in a 22 November 1941 letter, the results of the tests for the destroyers (USS MAHAN (DD-364), USS DRAYTON (DD-366), USS LAMSON (DD-367), and USS FLUSSER (DD-368)) were presented. A couple of weeks before the attack. A lot of "camo" experiments were going on prior to the attack on Pearl Harbor with directives changing all the time.
I'm as interested in these Task Force assignments myself. I knew that the Carriers were divided up as such, but I didn't know that a Battleship was assigned to at least some of them. Plus I didn't realize, or overlooked, that these Task Forces dated back to at least October 1941. In other TF databases as of 7 December 1941, BatDiv 2 & 4 were assigned to TF 1 and BatDiv 1 was assigned to TF 2. No Battleships were assigned to TF 3 (Scouting Force). I suspect that only these ships were listed as to being "evaluated" for this experiment.
