RDS-1 (first nuclear bomb) was tested in 1949. Stalin died in 1953. So it was definitely under Stalin's rule that nuclear program was developed.
It is fun to read about Russian chauvinism under Stalin rule, given the fact that he wasn't Russian himself.
Your comment said "missile".
Stalin ended socialist affirmative action programs (Korenizatsiya) that benefited Soviet minorities in education and local leadership. Russification policy and Cyrillization of local languages were enforced under him. Local Communist leaders who resisted the Russian chauvinist policies, like Fayzulla Khodjayev (the "Uzbek Lenin") and even the leaders of independent Mongolia, were dragged to Moscow and executed, which was a complete violation of socialist legality. Numerous Soviet minorities, from Chechens to Koreans, were forcibly deported to barren lands in Central Asia to make room for Russian settlers. NKVD records show that hundreds of thousands of forcibly migrated peoples died due to lack of food and shelter in the resettlement areas.
Stalin also said "I drink in the first place to the health of the Russian people because it is the most outstanding nation of all the nations forming the Soviet Union"
