HMCS Onondaga (S73) is an Oberon-class submarine that served in the Royal Canadian Navy and later the Canadian Forces. Built in the mid-1960s, Onondaga operated primarily with the Maritime Forces Atlantic until her decommissioning in 2000 as the last Canadian Oberon.
Several plans for the disposal of the submarine were made and cancelled before the Site historique maritime de la Pointe-au-Père in Rimouski purchased the boat for preservation as a museum vessel. The submarine was moved into location during 2008, and is open to the public.
The Oberon class were considered an improved version of the preceding Porpoise-class submarines, with a different frame of the pressure hull and constructed from a better grade of steel. These build differences allowed the Oberons to have a deeper diving depth at roughly 1,000 feet (300 m).
The submarines displaced 2,030 tonnes (2,000 long tons) surfaced and 2,410 tonnes (2,370 long tons) submerged. They measured 295 ft 1⁄4 in (89.922 m) long with a beam of 26 ft 1⁄2 in (7.938 m) and a draught of 18 ft (5.5 m).
The boats were powered by a two shaft diesel-electric system. The Oberons were equipped with two ASR 1 16-cylinder diesel engines creating 3,680 brake horsepower (2,740 kW) and two English Electric motors creating 6,000 shaft horsepower (4,500 kW). This gave the submarines a maximum surface speed of 12 knots (22 km/h; 14 mph) and a submerged speed of 17 knots (31 km/h; 20 mph). The boats carried 258 tons of oil giving them a range of 9,000 nautical miles (17,000 km; 10,000 mi) at 12 knots.
