Japanese Submarine I-30

Japanese Submarine I-30

I-30 was a Type B1 submarine of the Imperial Japanese Navy during World War II. After operating in the Indian Ocean she participated in a Yanagi mission, aimed at connecting Japan and Nazi Germany by submarine. She was the first Japanese submarine to reach Europe, arriving at Lorient, France in August 1942. I-30 returned to Singapore loaded with military technology and information, but hit a mine outside the harbour and sank. Only part of her cargo was salvaged.
