Operation Rising Sun

The story of the search for the Japanese submarine I-52 is one of two discoveries separated by time and purpose. In the dark of night in the Atlantic Ocean in 1944, U.S. Navy anti-submarine ships searched for a clandestine meeting between German and Japanese naval crews. Operating on captured intelligence, they sought to surprise and sink the two submarines. Half a century later, the I-52 still rested undiscovered on the seafloor, but this time the search was in the dark of the deep ocean in pursuit of possibility, not destruction.
