TheLambda 4SorL-4Swas an experimental Japaneseexpendable carrier rocket.It was produced byNissanand theInstitute of Space and Astronautical Scienceand launched five times between 1966 and 1970 withOhsumitechnology 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.^[2]^[3]

The Lambda 4S consisted of four stages, with twobooster rocketsaugmenting the first stage.SB-310rockets were used as boosters, with anL735first stage. The second stage was a reduced length derivative of the L735, whilst anL500was used as the third stage.^[4]The fourth stage was anL480S.All four stages burnedsolid propellant.^[3]

The Lambda 4S could place 26 kilograms (57 lb) of payload intolow Earth orbit.It was launched from theKagoshima Space Centre.Following its retirement in 1970, asounding rocketderived from it, theLambda 4SC,flew three times in order to test technologies for the Mu rockets to follow. TheMureplaced Lambda for orbital launches.
