Navy NewsStand has quite a few new pictures up of the DSRV Mystic, including this one:
Some other new pictures are here, here, here, and here; the last three are from inside the DSRV. I've never been inside a DSRV, but I have been over to the unit's buildings on North Island. Mystic and her sister Avalon are both pretty old, so hopefully the Navy is planning for their replacements. Has anyone heard of anything that's coming down the NAVSEA pipe?
