On 12 July 2006, the research vessel RV St. Barbara, a ship belonging to the Polish oil company Petrobaltic, found a 265-meter-long (869 ft) wreck 55 km (34 mi) north of Władysławowo, which they thought was most likely Graf Zeppelin. The wreck rests at a depth of more than 80 m (260 ft) below the surface. After the wreck was located, the Polish Navy began a two-day survey of the wreckage to confirm its identity.
