HONOLULU - From junked trucks to World War II submarines, vast fields of far-flung wreckage exist beneath the blue-green ocean off Hawaii.
"It's like an obstacle course under water, especially at Pearl Harbor," said John Smith, science program director at the Hawaii Undersea Research Laboratory. "Finding the more interesting artifacts is a real challenge."
A World War II-era Japanese submarine scuttled by the U.S. Navy is the laboratory's latest significant find among thousands of wrecks, most from the past two centuries.
The ship is one of two I-400 Sensuikan Toku class subs captured in the Pacific a week after Japan surrendered in 1945. Both subs were deliberately sunk by the U.S. when Russian scientists demanded access to them. The 400-foot-long hulks were the largest built before the nuclear ballistic missile subs of the 1960s.
