HMCS Calgary (FFH 335) is a Halifax-class frigate that has been serving the Royal Canadian Navy since her commissioning in 1995. As the sixth vessel of her class, she was constructed by MIL Davie Shipbuilding in Lauzon, laid down on 15 June 1991, launched on 28 August 1992, and officially commissioned on 12 May 1995. The vessel has a displacement of approximately 4,750 long tons and measures about 134.65 meters in length overall, with a beam of 16.36 meters and a draught of 4.98 meters. Calgary is powered by a CODOG propulsion system, featuring two General Electric LM2500 gas turbines that generate 47,500 shaft horsepower, coupled with a SEMT Pielstick diesel engine producing 8,800 shaft horsepower. This configuration allows her to reach speeds up to 29 knots and provides a range of approximately 7,000 nautical miles at 15 knots using her diesel engines, or about 3,930 nautical miles at 18 knots with gas turbines. The ship’s crew consists of around 198 personnel, including officers and aircrew. Fitted for multi-mission roles, Calgary's armament includes surface-to-surface Harpoon missiles, surface-to-air Sea Sparrow missiles, a 57mm Bofors main gun, and a Phalanx CIWS for close-in defense. She also carries anti-submarine weaponry such as the Mark 46 torpedoes and is equipped with helicopter facilities capable of operating CH-124 Sea King helicopters, including a "bear trap" system for launch and recovery in rough seas. Throughout her service, Calgary has participated in various operations including enforcing sanctions in the Persian Gulf, NATO blockades, anti-piracy patrols off the Horn of Africa, and drug interdiction missions in the Caribbean. She underwent a significant modernization under the FELEX program starting in 2012, which upgraded her combat systems, sensors, and missile systems to enhance her capabilities. Calgary’s operational history includes participation in international exercises such as RIMPAC and Talisman Sabre, deployments to the Pacific and East Asia, and involvement in maritime security operations enforcing UN resolutions. Notably, she recovered significant quantities of narcotics off Oman in 2021, demonstrating her ongoing strategic and tactical relevance in maritime security.
