There is nothing by that name in the database, so I can't look up its sensor.

EDIT: Are you talking about the Yugo Midget Subs assigned to the DPRK? If so, the stock database doesn't assign them any sensors at all. If you're using LWAMI they have a visual sensor and should be able to make periscope attacks--or at least could, if its weapon was ASUW capable. I guess we can add that to the list.
