rocket, produced under licence in Japan. It replaced the
N-I-rocket in Japanese use. It used a
Thor-ELT first stage, a Delta-F second stage, nine
Castor SRMs, and on most flights either a
Star-37E or
Burner-2 upper stage, identical to the US Delta 0100 series configurations. Eight were launched between 1981 and 1987, before it was replaced by the
H-I, which featured Japanese-produced upper stages. All eight launches were successful.
