The USSR started its nuclear program in 1943 after discovering that the USA,
Britain and Canada had already begun research into the development of an atomic bomb.
Assisted by intelligence from sources inside the USA’s Manhattan Project,
the USSR’s program developed quickly as the Soviets were able to replicate American successes
while avoiding some of their costlier mistakes. Although the majority of Cold War academics accept
that the USSR’s success had a lot to do with domestic expertise, they also recognise that
foreign intelligence helped to reduce the time it took for them to develop the bomb.
Work was accelerated after the bombings of Hiroshima and Nagasaki and took place in secret,
purpose-built cities dedicated to the nuclear program known as Atomgrads. By 1949 the Soviets
had developed two types of bomb and opted to detonate the simpler of the two designs first

The RDS-1 test was conducted in secret in an attempt to avoid the USA increasing its own
