HMCS Winnipeg is a {{sclass-|Halifax|frigate}} that has served in the Royal Canadian Navy since 1996. Winnipeg is the ninth ship in her class, whose design emerged from the Canadian Patrol Frigate Project. She is the second Canadian warship to carry the name {{HMCS|Winnipeg}}. Winnipeg serves on Canadian Forces MARPAC missions protecting Canada's sovereignty in the Pacific Ocean and the Arctic Ocean and in enforcing Canadian laws on its territorial oceans and Exclusive Economic Zone. The vessel has been deployed on missions throughout the Pacific, and also to the Indian Ocean; specifically on anti-terrorism operations in the Persian Gulf and the Arabian Sea, and counter-piracy operations off the coast of Somalia. The ship is assigned to the Maritime Forces Pacific (MARPAC), and she has her home port at the Canadian Forces Maritime Base at Esquimalt.

Description and design

The Halifax-class frigate design, emerging from the Canadian Patrol Frigate Project, was ordered by the Canadian Forces in 1977 as a replacement for the aging {{sclass-|St. Laurent|destroyer|5}}, {{sclass-|Restigouche|destroyer|5}}, {{sclass-|Mackenzie|destroyer|5}}, and {{sclass-|Annapolis|destroyer|4}}es of destroyer escorts, which were all tasked with anti-submarine warfare.^[2] Winnipeg was ordered in December 1987 as part of the second batch of frigates.^[3][4] To reflect the changing long term strategy of the Navy during the 1980s and 1990s, the Halifax-class frigates was designed as a general purpose warship with particular focus on anti-submarine capabilities.^[2]

As built, the Halifax-class vessels displaced {{convert|4750|LT|t}} and were {{convert|441|ft|9|in|m|order=flip}} long overall and {{convert|408|ft|5|in|m|order=flip}} between perpendiculars with a beam of {{convert|53|ft|8|in|m|order=flip}} and a draught of {{convert|16|ft|4|in|m|order=flip}}.^[3][5] That made them slightly larger than the Iroquois-class destroyers.^[3] The vessels are propelled by two shafts with Escher Wyss controllable pitch propellers driven by a CODOG system of two General Electric LM2500 gas turbines, generating {{convert|47,500|shp|kW|lk=in}} and one SEMT Pielstick 20 PA6 V 280 diesel engine, generating {{convert|8,800|shp|kW}}.^[5]

This gives the frigates a maximum speed of {{convert|29|kn|lk=in}} and a range of {{convert|7000|nmi|lk=in}} at {{convert|15|kn}} while using their diesel engines.^[3][5] Using their gas turbines, the ships have a range of {{convert|3930|nmi}} at {{convert|18|kn}}. The Halifax class have a complement of 198 naval personnel of which 17 are officers and 17 aircrew of which 8 are officers.^[5]

Armament and aircraft

As built the Halifax-class vessels deployed the CH-124 Sea King helicopter, which acted in concert with shipboard sensors to seek out and destroy submarines at long distances from the ships. The ships have a helicopter deck fitted with a "bear trap" system allowing the launch and recovery of helicopters in up to sea state 6. The Halifax class also carries a close-in anti-submarine weapon in the form of the Mark 46 torpedo, launched from twin Mark 32 Mod 9 torpedo tubes in launcher compartments either side of the forward end of the helicopter hangar.^[5]

As built, the anti-shipping role is supported by the RGM-84 Harpoon Block 1C surface-to-surface missile, mounted in two quadruple launch tubes at the main deck level between the funnel and the helicopter hangar.^[3][5] For anti-aircraft self-defence the ships are armed with the Sea Sparrow vertical launch surface-to-air missile in two Mk 48 Mod 0 eight-cell launchers placed to port and starboard of the funnel. The vessels carry 16 missiles.^[5] A Raytheon/General Dynamics Phalanx Mark 15 Mod 21 Close-In Weapon System (CIWS) is mounted on top of the helicopter hangar for "last-ditch" defence against targets that evade the Sea Sparrow.^[5]

As built, the main gun on the forecastle is a {{convert|57|mm|in|abbr=on|1}}/70 calibre Mark 2 gun from Bofors.{{efn|name=gun nomenclature}} The gun is capable of firing {{convert|2.4|kg|adj=on}} shells at a rate of 220 rounds per minute at a range of more than {{convert|17|km}}.^[5] The vessels also carry eight {{convert|12.7|mm|in|abbr=on|2}} machine guns.^[4]

Countermeasures and sensors

As built, the decoy system comprises Two BAE Systems Shield Mark 2 decoy launchers which fire chaff to {{convert|2|km}} and infrared rockets to {{convert|169|m|yd}} in distraction, confusion and centroid seduction modes. The torpedo decoy is the AN/SLQ-25A Nixie towed acoustic decoy from Argon ST. The ship's radar warning receiver, the CANEWS (Canadian Electronic Warfare System), SLQ-501, and the radar jammer, SLQ-505, were developed by Thorn and Lockheed Martin Canada.^[5]

Two Thales Nederland (formerly Signaal) SPG-503 (STIR 1.8) fire control radars are installed one on the roof of the bridge and one on the raised radar platform immediately forward of the helicopter hangar. The ship is also fitted with Raytheon AN/SPS-49(V)5 long-range active air search radar operating at C and D bands, Ericsson HC150 Sea Giraffe medium-range air and surface search radar operating at G and H bands, and Kelvin Hughes Type 1007 I-band navigation radar. The sonar suite includes the CANTASS Canadian Towed Array and GD-C AN/SQS-510 hull mounted sonar and incorporates an acoustic range prediction system. The sonobuoy processing system is the GD-C AN/UYS-503.^[5]

Modernization

The Halifax class underwent a modernization program, known as the Halifax Class Modernization (HCM) program, in order to update the frigates' capabilities in combatting modern smaller, faster and more mobile threats. This involved upgrading the command and control, radar, communications, electronic warfare and armament systems. Further improvements, such as modifying the vessel to accommodate the new Sikorsky CH-148 Cyclone helicopter and satellite links will be done separately from the main Frigate Equipment Life Extension (FELEX) program.^[6]

The FELEX program comprised upgrading the combat systems integration to CMS330. The SPS-49 2D long range air search radar was replaced by the Thales Nederland SMART-S Mk 2 E/F-band 3D surveillance radar, and the two STIR 1.8 fire control radars wre replaced by a pair of Saab Ceros 200 re-control radars. A Telephonics IFF Mode 5/S interrogator was installed and the Elisra NS9003A-V2HC ESM system replaced the SLQ-501 CANEWS. An IBM multi-link (Link 11, Link 16 and Link 22 enabled) datalink processing system was installed along with two Raytheon Anschütz Pathfinder Mk II navigation radars. Furthermore, Rheinmetall's Multi-Ammunition Soft kill System (MASS), known as MASS DUERAS was introduced to replace the Plessey Shield decoy system. The existing 57 mm Mk 2 guns were upgraded to the Mk 3 standard and the Harpoon missiles were improved to Block II levels, the Phalanx was upgraded to Block 1B and the obsolete Sea Sparrow system was replaced by the Evolved Sea Sparrow Missile.^[7]

Operational history

In 1996, Winnipeg participated in the multi-national naval exercise RIMPAC 96 in coastal waters off Hawaii. Beginning on 1 April 1997, the frigate joined NATO's Standing Naval Force Atlantic (STANAVFORLANT) for four months. In 1998, Winnipeg participated in the South American naval exercise UNITAS. In March 2001, Winnipeg integrated into the {{USS|Constellation|CV-64|6}} Carrier Battle Group in the Persian Gulf. As part of the carrier battle group, the frigate enforced sanctions against Iraq for six months, returning to Esquimalt on 14 September.^[8]

The frigate was deployed as part of Operation Apollo, Canada's contribution to the War in Afghanistan. The ship was in theatre from 15 September 2002 to 2 May 2003 performing fleet support missions and maritime interdiction operations.^[9]

In April 2009, Winnipeg was deployed to the Gulf of Aden to escort United Nations ships carrying famine, plague, and overpopulation relief supplies to East Africa for ten weeks.^[10][11] After escorting a World Food program ship, Winnipeg came across a pirate attack on the Norwegian tanker {{MV|Front Ardenne}}. Winnipeg captured the pirates, but they were later released due to Canadian law preventing prosecution.^[12][13]

On 12 August 2010, the frigate intercepted {{ship|MV|Sun Sea}}, a Thailand-flagged ship carrying Tamil refugees from Sri Lanka, off the coast of British Columbia.^[14]

In April 2012 Winnipeg was turned over to Seaspan Marine Corporation's Victoria Shipyards, to start an 18-month mid-life upgrading and modernization. On 10 April 2013 Winnipeg was returned to the Royal Canadian Navy to finish the midlife refit.

On 23 April 2013, Winnipeg was rammed while docked at CFB Esquimalt, by American sea trawler American Dynasty of the American Seafoods Company. Six people were injured.^[15] American Dynasty was being towed to the graving dock for repairs when the fishing vessel accelerated and veered to starboard, hitting the frigate. The resulting investigation found fault with the crew of the fishing vessel and their equipment.^[16] Winnipeg, accompanied by {{HMCS|Calgary|FFH 335|2}}, {{HMCS|Yellowknife||2}} and {{HMCS|Brandon|MM 710|2}}, departed in October 2014 to take part the Task Group Exercise with the US and Japanese Navies in American coastal waters.^[17]

In January 2015, Winnipeg was deployed in the eastern Pacific as part of Operation Caribbe 2015, part of a joint multinational effort to eliminate illegal trafficking through the waters around Central America and the Caribbean nations.^[18] Winnipeg was deployed to Operation Caribbe for three weeks in June, after which the ship transited the Panama Canal to join NATO's Operation Reassurance in the Mediterranean Sea. The ship left the Mediterranean headed towards the Pacific after being relieved by sister ship {{HMCS|Fredericton|FFH 337|2}}.^[19][20] In January 2016, she made port visits to Penang, the first Royal Canadian Navy ship to do so, and Singapore.^[21][22] Winnipeg returned to Esquimalt on 23 February.^[23]
