JSC ONSS was established in 1999, and since then has been developing exclusively at its own expense. For more than 20 years, the Joint-Stock Company "Association of Nizhny Novgorod Shipbuilders and Shipowners" has been successfully implementing a difficult, but extremely in-demand direction for the manufacture of domestic propeller and steering complexes, including shaft lines with fixed and adjustable pitch propellers with hydraulics and control systems, for ships and ships of almost all types and classes.
