I know there's been discussion about the whether or not American submarines returned to a dock celebration as did the Germans. I found the picture below at

this site:

It's of the
Wahoo returning to Pearl after its third patrol.
If you look very closely at the picture (go to the website), you'll see white spots where the wartime sensors blotted out the radar heads for the SD and SJ.
So, maybe with patch 1.3 Ubi should activate the fanfare at Pearl and add some people at the dock.
