Chief Directorate of the Northern Sea Route

The Chief Directorate of the Northern Sea Route (Russian: Главное Управление Северного Морского Пути, Glavnoe upravlenie Severnogo morskogo puti), also known as Glavsevmorput or GUSMP (Russian: ГУСМП), was a Soviet government organization in charge of the naval Northern Sea Route, established in January 1932 and dissolved in 1964.

The organization traces its roots to AO Komseveroput, a shipping company established by the Kolchak government and nationalized by the Bolsheviks. In May 1931 AO Komseveroput was reorganized into VO Glavkomseveroput; the organization employed 35,000 men scattered all over Arctic, as well as a sizable staff in Moscow and other mainland cities. A new office, Glavsevmorput, was established in December 1932 and absorbed VO Glavkomseveroput in May 1933. Overall management was assigned to arctic explorer Otto Schmidt, who had previously managed the Arctic Institute (VAI, later AANII). Glavsevmorput had its own Polar Air service Aviaarktika, headed by Mark Shevelev.

Glavsevmorput, in addition to Arctic shipping, also became the Soviet agency for exploiting resources across the far north and coordinating supplies and transport. Its aim was to contribute to the development of northern coastal Siberia; the office was empowered to establish seaports, conduct extensive research, and trade with the United States and Japan as was necessary to its principal function. The organization's quick unchecked expansion, especially in its Moscow offices, was initially masked by the successes of the 1934-1936 seasons.

However, the season of 1937, through a combination of unrealistic plans, bad weather and bad luck, was a disaster. Twenty-five of 64 ships dispatched on the route (many of them not fit for Arctic conditions) were trapped with crews and cargoes in the Arctic winter; one, Rabochiy, sank. The debacle, which coincided with the Great Purge led to a string of arrests; at least 673 Glavsevmorput personnel were arrested in a domino effect NKVD operation. The oversized organization was streamlined and stripped of auxiliary functions that were delegated to Dalstroy (land facilities) and Gostorg (foreign trade). Glavsevmorput was to concentrate exclusively on maintaining the Northern Sea route, specifically its coastal shipping line.
