Ulithi Atoll was occupied on this date with no opposition. The mogmog is reference to an islet at the atoll.

At the above site you will see murderess row of 5 aircraft carriers in a row by December.
Thanks for the link - the shot of those carriers was awe-inspiring (I’m assuming they were pretty confident no concentration of Japanese air power was likely to come down on them there).
Great pics.
The paint job on the carriers looks like the outline of a much smaller ship on the side.
