Photos History June 1, 1933 in the city of Leningrad on the Vyborg side was put into operation the plant "Vodtranspribor" - the first in Russia and plant for the production of hydroacoustic equipment. Today the Open Joint Stock Company "Vodtrnspribor", which is the legal successor of the plant, celebrates its 70th anniversary! The plant was the founder of 10 enterprises on the territory of the former Soviet Union, developing and producing a wide variety of hydroacoustic equipment. The first years the plant produced flashing equipment for lighthouses. This equipment was used to equip the Northern Sea Route, the White Sea-Baltic Canal, the Astrakhan roadstead, and the sluice part of the Dnieper basin. In January 1934, the first Soviet echo sounder was created at the plant. In the following years (1936-1938), a number of unique echo sounders for river and sea vessels were developed. In 1935-1937, the main direction of the plant's work was determined - the development and serial production of hydroacoustic equipment for the ships of the Navy - 90% of the total production. During this period, the first domestic sound-underwater communication devices and sound direction finders for submarines were created and mastered in production. In 1940, the Orion complex hydroacoustic system and the Tamir-1 ultrasonic station for surface ships were successfully tested. These systems completed the first stage in the development of the Russian Navy's hydroacoustics. During the Great Patriotic War, the plant produced various hydroacoustic equipment, first of all, Mars-type sound direction-finding stations and Tamir ultrasonic stations. The equipment of the plant and repair work on the ships were highly appreciated by the seamen of the Baltic and Northern fleets. In the post-war years, the plant was tasked with creating new types of hydroacoustic equipment. To solve them, a Special Design Bureau (OKB-206) was created at the plant in 1946. 1960-1966 years marked a new stage in the development of hydroacoustic technology. New sonar systems were developed. From 1959 to 1966, the plant mastered more than 20 types of new hydroacoustic stations. A large number of sonar equipment has been exported to Bulgaria, Romania, Poland, Yugoslavia, Indonesia, India, Algeria, China. In 1973, the Okeanpribor research and production association was created, which included VodtranspriborZavod, which was the ancestor and creator of almost the entire hydroacoustic industry in the country.) In 1993, Vodtranspribor OJSC was founded - the successor to the best traditions of the plant, which remains today the flagship of the domestic industrial hydroacoustic instrumentation for the Russian Navy.
