This was China's sixth nuclear test, and its first full scale radiation implosion (Teller-Ulam) weapon test. It was conducted only 32 months after the first atomic test, the shortest elapsed time for any nuclear weapons state. The device contained U-235, lithium-6 deuteride, and U-238. It was detonated at 2960 m over the Lop Nur Test Ground after being dropped from an H-6
