The All-Russian Scientific Research Institute of Experimental Physics (VNIIEhF) is the former Soviet Union's premier research and development center for nuclear weapons. The first Soviet atomic bomb was developed here in the late 1940s, after which the center continued as a center for nuclear weapons research. Many of the Soviet Union's best physicists were associated with Arzamas-16: Academician Andrey D. Sakharov worked here for nearly 20 years, and Academician Yuliy B. Khariton still serves as the Center's scientific head.
