The HMCS Huron Screw was the port propeller on the Huron, one of four Tribal Class destroyers designed and built in Canada. The HMCS Huron was commissioned in Halifax on 16 December 1972 and decommissioned on 31 March 2005 in Esquimalt, British Columbia. Used as a target, she was sunk by weapons fire during an exercise on 14 May 2007. Her final resting place is 49° 58.5°N, 127° 58.6W at a depth of over 1000m, about 200 km west of Vancouver Island.
The HMCS Huron Screw is a Controllable Reversible Pitch Propellor, designed such that the pitch of the blades can be changed to obtain optimum efficiency over a large range of speeds. The ability to change propellor pitch allowed the ship to move in both the forward or reverse directions without changing the direction of rotation of the propellor shaft.
The Huron's propellor is almost 14 feet (4.2 m) in diameter and is made of Nickel Aluminum Bronze alloy. It could propel the ship at a forward speed of almost 30 knots and an astern speed of 17 knots. The time from full ahead to full astern was approximately 2 minutes. The propellor weighs just over 13,500 lb or 6,140 kg.
The Military Museums and the Naval Museum of Alberta would like to thank our sponsors, volunteers and especially the ASU (Area Support Unit) for their efforts in the acquisition, assembly and unveiling of the HMCS Huron Screw.
