Design and description

The ''Kingston'' class was designed to fill the minesweeper, coastal patrol and reserve training needs of the Canadian Forces, replacing the s, s and Royal Canadian Mounted Police coastal launches in those roles.Macpherson and Barrie, p. 299 In order to perform these varied duties the ''Kingston''-class vessels are designed to carry up to three ISO containers with power hookups on the open deck aft in order to embark mission-specific payloads.Saunders (2008), p. 95 The seven module types available for embarkation include four route survey, two mechanical minesweeping and one bottom inspection modules.

The coastal defence vessels are powered by four Jeumont ANR-53-50 alternators coupled to four Wärtsilä UD 23V12 diesel engines creating . Two LIPS Z-drive azimuth thrusters are driven by two Jeumont CI 560L motors creating and the Z drives can be rotated 360°. This gives the ships a maximum speed of and a range of at .Saunders (2004), p. 92

The ''Kingston'' class is equipped with a Kelvin Hughes navigational radar using the I band and a Kelvin Hughes 6000 surface search radar scanning the E and F bands. The vessels carry an AN/SQS-511 towed side scan sonar for minesweeping and a Remote-control Mine Hunting System (RMHS). The vessels are equipped with one Bofors 40 mm/60 calibre Mk 5C gun and two M2 machine guns. The 40 mm gun was declared obsolete and removed from the vessels in 2014. Some of them ended up as museum pieces and on display at naval reserve installations across Canada. The ''Kingston''-class coastal defence vessels have a complement of 37.

Service history

''Yellowknife'' keel was laid down on 7 November 1996 by Halifax Shipyards Ltd. at Halifax, Nova Scotia and was launched on 5 June 1997. The coastal defence vessel transferred to the west coast in January 1998 and was commissioned into the Canadian Forces on 18 April 1998 at Esquimalt, British Columbia and carries the hull number MM 706.Macpherson and Barrie, p. 304 On 4 June 1999, the vessel collided with another minesweeper during operations off Victoria, British Columbia while trying to avoid floating obstacles. On 18 June 1999 the vessel was given freedom of the city of Yellowknife, Northwest Territories.

''Yellowknife'', accompanied by frigates and and sister ship , departed in October 2014 to take part in San Francisco Fleet Week and the Task Group Exercise with the US Navy in American coastal waters. Following those exercises, ''Yellowknife'' and ''Brandon'' deployed as part of Operation Caribbe, completing their tour on 4 December. In June 2016, ''Calgary'', , and ''Yellowknife'' sailed from Esquimalt to participate in the RIMPAC naval exercise. After reports surfaced of a lost nuclear bomb was discovered off the coast of British Columbia, ''Yellowknife'' was sent to investigate and recover the item. Divers from ''Yellowknife'' determined the object was not the missing bomb. From August to September 2017, ''Yellowknife'' and sister ship sailed to the Arctic Ocean to perform surveillance of Canada's northern waters as part of Operation Limpid. They returned to Esquimalt on 5 October.

In June and July 2018, ''Yellowknife'' and sister ship were deployed off the coast of Southern California while taking part in RIMPAC 2018.
