This is a full-scale replica of the Pencil test rocket developed in Japan by the University of Tokyo in 1955 and was the smallest vehicle of its type. The rocket was so-called because of its size. The weight of a fully loaded average Pencil was less than half a pound. Yet, these rockets were precision scientific tools fired on a horizontal firing range to test several important aerodynamic factors.

After the Pencil series, the Japanese built and flew the slightly larger Baby-T rockets, then larger Kappa followed by Lambda rockets. From there on, the Japanese progressed rapidly and in 1970, launched their first satellite, the Ohsumi, using a four-stage Lambda 4S solid fuel rocket. The Pencil rocket was donated in 1994 to the Smithsonian by the Institute of Space and Astronautics of Japan.
