Versions of the Delta rocket built under license in Japan using American and Japanese components and used to launch NASDA (National Space Development Agency) satellites. The N-1 (not to be confused with the giant Soviet N-1) launched seven satellites in 1975-82 and could place up to 130 kg in geostationary orbit (GSO). The larger N-2 launched eight satellites in 1980-86 and had a GSO payload capacity of 350 kg. The “N” prefix is taken from the first letter of “Nippon” (Japan).
