1978 Soviet nuclear tests

The Soviet Union's 1978 nuclear test series was a group of 31 nuclear tests conducted in 1978. These tests followed the 1977 Soviet nuclear tests series and preceded the 1979 Soviet nuclear tests series.

According to an article that appeared in 2010 on the Russia state broadcaster RT, on November 17, 1978, the USSR detonated its first neutron bomb. However this test detonation, if it indeed occurred on the date given, has no other known references to support this date.
