Sakharovsky was born to a working-class family in
Kostroma Oblast, on 3 September 1909. His family moved to
Leningrad when he was a child, and he began his career as a
welder at the
Baltic Shipyard. He joined the Communist Youth League (
Komsomol) in 1926, and was accepted as a full member of the
Communist Party of the Soviet Union in 1930. In 1931 he was drafted into the
Red Army for military service, and initially he was assigned to the 2nd Signals Regiment of Leningrad, but soon, recommended by the Komsomol, he was sent to study at the
Lenin Military-Political Academy, graduating in October 1933. By decision of the
Political Directorate of the Red Army, he was then sent to the post of secretary of the Komsomol bureau of the 63rd Construction Battalion, which performed public works in
Sovetskaya Gavan of the
Far Eastern Territory. Demobilized in December 1934, Sakharovsky returned to Leningrad, initially working in political propaganda at the
Northern Shipyard. In 1935, he was elected secretary of the Komsomol committee of the "Kanonersky"
ship repair plant in Leningrad. In July of the same year, he was assigned to the
Baltic Sea Shipping Company, as an instructor in the political department for the Marxist–Leninist education of the company's personnel. In February 1938, he was elected secretary of the shipping company's party committee. ==World War II==
