Operation Deadlight
From Wikipedia, the free encyclopedia
Operation Deadlight was the code name for the scuttling of U-boats surrendered to the Allies after the defeat of Germany near the end of World War II.
Of the 154 U-boats surrendered, 121 were scuttled in deep water off Lisahally, Northern Ireland or Loch Ryan, Scotland in late 1945 and early 1946. On February 12, 1946 at 10:04 a.m., U 3514 received the dubious honor of being the last U-boat sunk by Operation Deadlight. The other 33 were used for various tasks and then sunk. An example is U 1105, which sunk on explosives trial in the Potomac in 1948.
The British Ministry of Defence has awarded a salvage contract to a firm that plans to raise most, if not all, of the U-boats scuttled under Operation Deadlight[1]. Since all steel produced post-1945 contains a degree of radioactivity[2], sunk steel ships, such as those scuttled during Operation Deadlight or at Scapa Flow represent one of the few sources of non-radioactive steel, required for manufacture of instruments measuring radioactivity, amongst other things. As such, this 'clean' steel is worth far more than normal steel contaminated with the trace amounts of radioactivity left in the air, and this makes salvage economically viable. Lead contamination is also becoming an issue in recycled steel.
Several U-boats escaped Operation Deadlight. Some were claimed as prizes by Britain, France, Norway and the Soviet Union. Four were in the far east when Germany surrendered and were commandeered by Japan (U 181 got name I-501, U 195 - I-506, U 219 - I-505, U 862 - I-502, and fifth boat U 511 was sold to Japan in 1943 and got new name RO-500)[3]. Two U-boats that survived Operation Deadlight are museum ships today. U 505 was slated for scuttling but Rear Admiral Daniel V. Gallery argued successfully that she did not fall under Operation Deadlight. United States Navy Task Group 22.3, under then-Captain Gallery, had captured U 505 in battle on 4 June 1944. Having been captured, not surrendered at the end of the war, she survived to become a war memorial at the Museum of Science and Industry in Chicago. U995 was transferred to Norway by Britain in October 1948 and became the Norwegian Kaura. She was returned to Germany in 1965 to become a museum ship in 1971.
