The Kankoh-maru (観光丸, Kankōmaru) is the name of a proposed vertical takeoff and landing (VTVL), single-stage-to-orbit (SSTO), reusable launch system (rocket-powered spacecraft). According to a document from July 1997, it would have been manufactured by Kawasaki Heavy Industries and Mitsubishi Heavy Industries, with its formal name being the Kawasaki S-1.[1]

Overview

The concept was created by the Japanese Rocket Society [ja] in 1993.[2][need quotation to verify] This development cost was estimated ¥2.67 trillion ($28 billion) in 1995.[2][need quotation to verify]

The name Kankō Maru is derived from the first steam-powered vessel in Edo-era Japan.[2]
