HMCS Saguenay and HMCS Skeena had steam turbine engines, one of which is seen here, that could drive them through the water at speeds of well over 30 knots (55 km/h).

These state-of-the-art engines and the oil-fired boilers that fed them occupied considerable space in the destroyers' long and narrow hulls. Steam turbine technology, developed in the late nineteenth century, permitted warships to travel at high speeds for extended periods. By the 1930s, turbines propelled destroyers at speeds which would have kept pace with many First World War torpedoes.
