In 1991, Bill Nagle. A former wreck diver and the captain of Seeker , learned about a wreck off New Jersey and decided to mount a diving expedition to the site. On September 2, 1991, an unidentified U-boat wreck was discovered 73 meters (240 feet) deep a hazardous depth for standard scuba diving. Off the coast of New Jersey. Nicknamed U-Who , the exact identity of the wreck was a matter of frequent debate, and initially the wreck was thought to be either U-550. The discoverers of U-Who , John Chatterton. Continued to dive the wreck for the next several years, taking considerable risks. Three divers, Steve Feldman. Chris Rouse and Chris Rouse, Jr. Eventually, the team recovered a knife inscribed with “Horenburg”, a crew member’s name. However, they learned at the U-boat archives that U-869 was supposedly sent to Africa, so this piece of evidence was initially disregarded. A few years later, they found part of the UZO torpedo aiming device, and spare parts from the motor room engraved with serial and other identifying numbers. On August 31, 1997 they concluded that the boat they found was U-869. The location of the wreck is approximately. 39.54889°N 73.33222°W. 39.54889; -73.33222. The men who found U-869 believed it was a victim of its own torpedo, which may have become a “circle-runner”. Torpedoes manufactured later in the war had acoustical seeking capability. It was theorized that the torpedo was initially fired in a turning pattern and when it missed its target, it picked up the sound of the submarine’s propeller. At least two other German U-boats supposedly have been lost due to their own torpedoes: U-377. In 1944 and U-972. Chatterton and Kohler based their theory largely on a lack of evidence to support other causes for sinking. They claimed there was no reported naval activity in the vicinity, thereby ruling out a sinking by attack. Moreover, the damage to the hull was from the outside and thereby ruled out an internal explosion. This problem also affected the US submarine force at least twice, as seen with USS Tang (SS-306). And USS Tullibee (SS-284). DIMENSIONS OF PRINT ARE 22″ x 17″. The item “U-WHO (U-869 PRINT)” is in sale since Wednesday, August 03, 2016.
