L series (Japanese rockets)
L-4S #5 on its launch pad.
The Lambda series, or L series, was Japan's first family of orbital launch vehicles. The rockets in this family were effectively scaled-up versions of the solid-propellant Kappa sounding rockets. The fifth launch of an L-4S placed Japan's first artificial satellite, Ohsumi, in orbit on Feb 11, 1970.
