RDS-37 was a Soviet name for their first nuclear test of a "true" hydrogen bomb.

Its power was roughly equivalent to 1.6 megatons of TNT.

It was their first in the megaton range and was on November 22, 1955. It was a multi-stage thermonuclear device which utilized radiation implosion called Sakharov's "Third Idea" in the USSR (the Teller-Ulam design in the USA). It was at Semipalatinsk Test Site, Kazakhstan. The Joe Four device exploded in 1953 was labeled as a "hydrogen bomb" as well but was more similar to a "boosted" fission bomb than a megaton range hydrogen bomb.
