The Kankoh-maru (観光丸, Kankōmaru) is 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

[edit]

The concept was created by the Japanese Rocket Society [ja] in 1993.[3] This development cost was estimated ¥3.8 billion (1995) (US$40.4 million) in 1995.[4]

The name Kankō Maru is derived from the first steam-powered vessel in Edo-era Japan.[3]
