Submarines of the Imperial Japanese Navy
The submarines that Electric Boat sold to Japan were based on the Holland designs, known as Holland Type VIIs similar to the American s. The five imported Hollands were originally built at Fore River Ship and Engine Company in Quincy, Massachusetts under Busch's direction for the Electric Boat Company back in August–October 1904. They were shipped by freighter from Seattle, Washington in Knock-down kit form to Japan, and then reassembled by Arthur Leopold Busch at the Yokosuka Naval Arsenal, which was then Japan's largest naval shipyard, to become Hulls No. 1 through 5 and were designated Type 1 submarines by the Japanese Navy.
Japanese submarine I-1
The Japanese submarine "I-1" was a "J1 type" submarine built by Kawasaki, Kobe, for the Imperial Japanese Navy. She was a large cruiser submarine displacing 2,135 tons and was the lead of four boats built in the class.
She was commissioned on 10 March 1926 and served in the Second World War. On 29 January 1943, during Operation Ke, the New Zealand naval trawlers "Kiwi" and "Moa" intercepted and wrecked her after a surface battle at Kamimbo Bay, Guadalcanal.On 29 January 1943 she encountered the New Zealand minesweepers, "Kiwi" and "Moa". Unable to penetrate "I-1"s hull with their deck guns, the minesweepers rammed and chased her to shallow water, eventually driving her aground on the reef at Kamimbo Bay, Guadalcanal. The wreck partially protrudes from the water.
