Recovery of the I-52

The I-52 was the largest and most technologically advanced submarine of it's time. Code named Momi (Evergreen in Japanese), the I-52 was a C3 cargo sub that was 356' long with a beam of 30.5'. The I-52 had a top speed of 17.7 knots (20.5 mph) on the surface and 6.5 knots (7.5 mph) submerged. The I-52 had a range of 21,000 nautical miles without refueling. As a cargo sub, the I-52 had a carrying capacity of 300 tons. At the time she was sunk her cargo included 120 tons of tin ingots, 59.8 tons of raw rubber, 11 tons of tungsten, 9.8 tons of molybdenum, 3.3 tons of quinine, 3 tons of opium, and 2.2 tons of gold bars. This cargo was to be used to pay for the technology exchanges between Japan and Germany. On board were 95 officers and crew, 14 civilian engineers from Japanese companies, and 3 German officers who were transfered onto the I-52 from the U-530. Radio transmissions were intercepted and decoded by the US, pinpointing the I-52's position. The I-52 was sank on June 24, 1944, by US Avengers dispatched from the USS Bogue, shortly after her rendevous with the German sub, the U-530. Lost for over 5o years, the I-52 was found, after 5 years of research, on May 2, 1995 by Paul Tidwell. The I-52 is amazingly intact and well preserved in water 17,000 feet deep. Her identification numbers can still be clearly read on the conning tower. Now the recovery story of I-52 is about to begin and you can be a part of this historical event.
