[English] This submarine propeller was used on Canadian Oberon class submarines. The Oberon class was a 27-ship class of British-built diesel-electric submarines based on the successful British Porpoise class submarine. 3 of these submarines were purchased in 1964 and built for the Royal Canadian Navy. These submarines were decommissioned in 2000 and all but 1 have been sold for scrap. The remaining submarine is on display in Pointe-au-Père, Quebec as a museum.

Excerpt: The Oberon class was a ship class of 27 British-designed submarines operated by five nations. They were designed as a follow-on from the Porpoise class; physical dimensions were the same but stronger materials were used in hull construction and improved equipment was fitted. The Oberons operated during the Cold War, with duties including surveillance, tracking of other ships and submarines, delivery and retrieval of special forces personnel and serving as targets for anti-submarine training.
The class used diesel-electric propulsion, with lead-acid

batteries to provide power when the engines cannot be used. Each vessel has two Admiralty-pattern V-16 diesel engines, each driving one 1280-kW 880-V generator. These can provide power directly to the two 3,000-brake-horsepower (2,200 kW) electric motors, one directly connected to each propeller.
The three Canadian submarines were built with improved air-conditioning systems, while as many common components as possible were replaced with Canadian equivalents. The Canadian Oberons used United States Navy torpedoes throughout their career: they were initially equipped with Mark 37 torpedoes, but were later upgraded for the Mark 48s.
The three boats were given First Nations names: Ojibwa, Onondaga and Okanagan. They entered service on 23 September 1965, 22 June 1967 and 22 June 1968 respectively for service as “clockwork mice”, submarines used to train surface vessels in anti-submarine warfare. Two further Oberons were acquired but never commissioned into the Canadian Navy.
