All I know is that the San Diego Maritime Museum was only obligated to keep the B-39 through 2011.
Then I read this article the other day:

"Plans call for the ship to open as a paid attraction in 2012, when it joins the museum's other ships at the nearby embarcadero. It'll take the spot now occupied by B-39, a Soviet submarine that will be turned into an offshore diving reef."
Apparently, SDMM will keep the B-39 only as long as they are obligated and then sink her.
