The Mitsubishi Shinten (震天, Quaking Sky) was a two-row, 14-cylinder air-cooled radial engine built by the Mitsubishi Aircraft Company for the Imperial Japanese Army Air Service (IJAAS) and the Imperial Japanese Navy Air Service (IJNAS) in the early 1930s. Like many aircraft engines in Japan, there were multiple designations for this engine. The company model designation was A6(7) while it was an experimental engine project. Once accepted, it was known as the "Shinten" or MK1 by the IJNAS, and Ha6 by the IJAAS.
