Scholars dispute the authenticity of RDS-6 as a thermonuclear device as it did not manage to produce a yield consistent with a true hydrogen bomb. Y-12 was already the main source of machining and manufacture of the necessary nuclear parts for the weapons being stockpiled and for the tests being conducted.
