No, that looks to be a picture of a sub of the same class of the missing sub with the Brazilian entrepeneur in front of it. The sub in the photo is part of the German submariners memorial in Kiel, Germany. It commemorates those lost in subs in WW I and WWII. I’ve got a picture of myself in front of that sub when I was on vacation as a teenager. The entreprenuer was likely doing research on the one he was looking for.
Just looked it up. It’s the Laboe Sailors memorial. which commemorates the sailors lost in all navies during the world wars. Adjacent to Kiel harbor.
