China's first nuclear weapons test (596), detonated on October 16th 1964, Lop Nur test site.

The People's Republic of China's first nuclear weapons test (called 596, and originally named by the US intelligence agencies Chic-1), detonated on October 16, 1964, at the Lop Nur test site. It was a uranium-235 implosion fission device made from weapons-grade uranium (U-235) enriched in a gaseous diffusion plant in Lanzhou.[2] The bomb had a yield of 22 kilotons, comparable to the Soviet Union's first nuclear bomb RDS-1 in 1949 and the American Fat Man bomb dropped on Nagasaki, Japan in 1945.[3] With the test, China became the fifth nuclear power.
