What year did the Society Union complete the atomic bomb?

The Joe-1 (seemed by the United States) was first tested in 1949

Assuming "Society Union" is an autocorrection of the "Soviet Union":

The Soviet Union 'completed' the atomic bomb, RDS-1 (called Joe-1 by the United States), by doing a test detonation in 1949. As a result, more RDS-1 bombs were created by the following year.
