The Halifax-class frigate (hull designation FFH) is a multi-role patrol frigates that have served the Canadian Forces since 1992.
HMCS Halifax (FFH 330) The Halifax-class are the work horses of Maritime Command (MARCOM) which deploys them extensively in task groups. In 2007 a planned refit of the Halifax class known as the Halifax Class Modernization Project (HCMP) or alternately as the Frigate Life Extension (FELEX).The primary weapon of Halifax-class ships is the CH-124 Sea King helicopter, which acts in concert with shipboard sensors to seek out and destroy submarines at long distances from the ships.new maritime helicopter, the CH-148 Cyclone, which is slated to replace the Sea King, will be deployed onboard the frigates. The Halifax-class also carries a close-in anti-submarine weapon Mark 46 torpedo, launched from Mark 32 Mod 9 torpedo tubes in launcher compartments either side of the forward end of the helicopter hangar.
RGM-84 Harpoon Block 1C anti-shipping missile, mounted in two quadruple launch tubes at the main deck level between the funnel and the helicopter hangar.the ships are armed with the Sea Sparrow vertical launch surface-to-air missile in eight-cell launchers.A Raytheon/General Dynamics Phalanx Mark 15 Mod 1 close-in weapon system (CIWS) is mounted on the roof of the helicopter hangar for "last ditch" defense against targets that evade the Sea Sparrow. MARCOM has ordered upgrade kits to convert to the Phalanx Block 1B. The Block 1B upgrade includes a Thales Optronics HDTI5-2F thermal imager, improved Ku-band radar and longer gun barrel with a dual firing rate of 3000 or 4500 rounds/min.
The main gun is a 57 mm 70 Mark 2 gun from Bofors. The gun is capable of firing 2.4 kg shells at a rate of 220 rounds/min at a range of more than 17 km. The Bofors is a multi-purpose weapon usable against surface and air targets

The Canadian Patrol Frigate Program has not been without its problems. The diesel engine is raft-mounted to reduce radiated noise but this was found to be noisier than expected. HMCS MONTREAL (FFH-336) had 12,500 synthetic rubber anechoic tiles applied on the exterior of the underwater hull in the area of the engineering spaces to attempt to reduce radiated noise. Inspections in 1993 on HALIFAX, HMCS VILLE DE QUÉBEC (FFH-332) and HMCS TORONTO (FFH-333) showed propulsion diesel cracking problems that restricted the frigate’s speed to between 13–15 knots on diesel power. The problem was not seen to until the three ships went into refit during 1995–96. The last of what became a twelve ship class, HMCS OTTAWA (FFH-341), entered service in 1996.
Equipped with the Thales UYQ-501(V) Shipboard Integrated Processing and Display System (SHINPADS) data system, the crew processes information gathered from the frigate’s Ericsson Sea Giraffe 150HC air-surface search radar and Raytheon SPS-49(V)5 long-range air search radar as well as its SQS-505(V)6 hull-mounted sonar and SQR-501 CANadian Towed Array Sonar System (CANTASS), a passive-only towed array which is located at the stern of the ship. CANTASS is to be replaced by the TIAPS (Towed Integrated Active-Passive Sonar) system in the near future.
For surface and anti-submarine duties HMCS halifax class is equipped with two paired, fixed 324-mm Mk 32 ASW Torpedo Tubes that can fire the Raytheon Mk 46 Mod. 1 or 5 torpedo.
Located next to the VLS on both sides are 8 RGM-84C/D Harpoon SSM in two 4 cell launchers. Unlike most ships, HMCS halifax class’s Harpoon face inwards, the launch exhaust is not expended on the deck, rather over the side of the ship, causing less damage.
For air defence HMCS halifax class can call on 16 RIM-7M Sea Sparrow missiles located in two 8 cell Vertical Launch SAM launchers positioned outside the hull on either side of the ship’s funnel. The HALIFAX class is the first to mount VLS in this manner and it has several advantages, including easy removal of the launcher if necessary.
The frigate’s Electronic Warfare Suite consist of the Racal SLQ-504 (CANEWS) intercept jamming system, the Lockheed SLQ-503 Reprogrammable Advanced Multimode Shipboard ECM System (RAMSES) jamming system. HMCS halifax class has 4 six-round SLQ-502 (Marconi-GEC Shield-II) decoy launchers located either side of the bridge. Located next to the CANTASS is the Aerojet SLQ-25 Nixie towed acoustic torpedo decoy system.
HMCS halifax class has a hanger bay and flight deck which can support one CH-124 Sea King helicopter. With a crew of 4 (two pilots, navigator and airborne sensor operator) the Sea King is equipped with a dipping sonar and can be armed with 2 MK-46 lightweight torpedos. The Sea Kings can perform various missions from anti-submarine to search and rescue. The Canadian Air Force (CAF) operates the helicopter detachment. The flight deck has the Indal Bear Trap helicopter haul-down and deck transit system installed. Similar to the RAN’s RAST helicopter downhaul and traversing system, Bear Trap can operate in the very heavy seas of the North Atlantic.
HMCS halifax class is powered by two G.E. LM-2500-30 gas turbine engines with one SEMT-Pielstick 20PA6-V280-BTC diesel engine turning two screws that can move the ship at 29 knots. HMCS halifax class’s range is 4,500 Nautical Miles at 20 knots on one gas turbine, while operating the diesel the range can extend to 6,000 nautical miles at 15 knots. HMCS halifax class has a fuel load over 500 tons.
