SA-15 is the project name for a series of icebreaking multipurpose cargo ships built in Finland for the Soviet Union in the 1980s. The ships, capable of independent operation in all prevailing arctic ice conditions, were the first merchant vessels designed for year-round operations in the Northern Sea Route. For this purpose they have hulls that resemble those of polar icebreakers and propulsion systems capable of withstanding ice loads. While the ships are also known as the Norilsk class after the first ship, Norilsk, they are usually referred to by their project name which denotes a subarctic 15,000 DWT cargo ship. Nineteen SA-15 class ships were delivered by Finnish shipbuilders Wärtsilä and Valmet in 1982–1987, and (As of 2020) two vessels remain in service.
