The Lambda 4S or L-4S was an experimental Japanese expendable carrier rocket. It was produced by Nissan and the Institute of Space and Astronautical Science and launched five times between 1966 and 1970 with Ohsumi technology demonstration satellites. The first four launches failed, however the fifth, launched on 11 February 1970, successfully placed Ohsumi-5, the first Japanese satellite, into orbit.^[1]^[2]

The Lambda 4S consisted of four stages, with two booster rockets augmenting the first stage. rockets were used as boosters, with an first stage. The second stage was a reduced length derivative of the L735, whilst an was used as the third stage.^[3] The fourth stage was an . All four stages burned solid propellant.^[2]

The Lambda 4S could place 26 kilograms (57 lb) of payload into low Earth orbit. It was launched from the Kagoshima Space Centre. Following its retirement in 1970, a sounding rocket derived from it, the , flew three times in order to test technologies for the Mu rockets to follow. The Mu replaced Lambda for orbital launches.
