Two Bombs, One Satellite (Chinese: 两弹一星; pinyin: Liǎngdàn Yīxīng) was an early nuclear and space project of the People's Republic of China. Two Bombs refers to the atomic bomb (and later the hydrogen bomb) and the intercontinental ballistic missile (ICBM), while One Satellite refers to the artificial satellite. China tested its first atomic bomb and first hydrogen bomb in 1964 and 1967 respectively, combining the atomic bomb with surface-to-surface missile in 1966, and successfully launched its first satellite (Dong Fang Hong I) in 1970.
