A view of the U.S. Navy "Los Angeles"-class nuclear-powered attack submarine USS "Chicago" (SSN-721) during routine hull maintenance and painting in the medium auxiliary repair dock USS "Arco" (ARDM-5) at the San Diego Submarine Base, California (USA). The "Chicago" sports a Bulls-type logo on its nose in appreciation of the Chicago Bull's recent victory in the NBA championship games. The bull probably washed off after three or four dives. The chalk painting was done by Boatswain's Mate 3rd Class Curt L. Tucker.
