English: 090529-N-0000X-052 ARGENTIA, Newfoundland, Canada - In this undated file photo Lt. Cmdr. Ted Davis wears a medal created for him by crew members of the Tench-class diesel submarine USS Grenadier (SS 525) in recognition of his leadership during the tracking of a Soviet Zulu-class submarine that led to the first documented evidence that the Soviet Union was conducting submarine operations in the Atlantic Ocean. The event culminated shortly after midnight on May 29, 2009, more than 18 hours after the Soviet submarine was first located by Grenadier's sonar operators. The medal, made out of a mayonnaise lid and pieces of an old flag, and nicknamed the "Arleigh Medal" after then-Chief of Naval Operations Arleigh Burke, was returned by Davis nearly 45 years later to Willie Dunagan, a Radioman 2nd Class aboard Grenadier, who was one of several crewmembers who created the medal.
