Yamato-1 is a ship built in the early 1990s by Mitsubishi Heavy Industries, Ltd. at Wadasaki-cho Hyogo-ku, Kobe. She uses magnetohydrodynamic drives (MHDs) driven by liquid helium-cooled superconductors and can travel at 15 km/h (8 knots). Yamato-1 was the first working prototype of her kind. She was completed in Japan in 1991, by the Ship & Ocean Foundation (later known as the Ocean Policy Research Foundation). The ship, which includes two MHD thrusters, which have no moving parts, was first successfully operated in Kobe harbour in June 1992. An MHD works by applying a magnetic field to an electrically conducting fluid. The electrically conducting fluid used in the MHD thrusters of Yamato-1 is seawater. In the 1990s, Mitsubishi built several prototypes of ships propelled by MHD systems. Despite projected higher speeds, these ships were only able to reach speeds of 15 km/h. Today Yamato-1 is on display at the Kobe Maritime Museum. {{Gallery|width=180|lines=3|File:Yamato1 1.jpg|Yamato-1 on display in Kobe, Japan| File:Yamato 1 from the front.JPG|The front of Yamato-1| File:Yamato 1 thruster.jpg|A MHD thruster from the boat, at the Ship Science Museum in Tokyo| File:Magnetohydrodynamic drive.jpg|View of one end of the magnetohydrodynamic drive fitted to the vessel| File:Kobe Maritime Museum-A bird's-eye view from Kobe Port Tower.jpg|Yamato-1 in front of the Kobe Maritime Museum| }} Further reading
