Anticosti - class Auxiliary Minesweepers
The
Anticosti - class auxiliary minesweepers were a class of two former oil rig logistics support vessels that were acquired by the Royal Canadian Navy in 1988. In the late stages of the Cold War, the RCN was in a difficult financial situation, as the majority of the fleet was required to either be replaced or modernized at a time when the Canadian public was increasingly calling for the defence budget to be reigned in. In an effort to preserve some of its niche capabilities, the RCN made the decision to spin off some of its non-core roles, such as minesweeping and coastal operations, to the Naval Reserve.
The Naval Reserve was at that time operating six former
Bay - class minesweepers of late 1950s vintage, however, they had been converted to patrol escorts and reassigned to the West Coast Training Squadron with their minesweeping gear removed. It was determined that a new class of minesweepers would need to be procured, but such a vessel would not be available until at least the mid-90s, as Canadian shipyards were preoccupied with the construction of the
Halifax - class frigates. In the interim, it was decided to procure and convert two civilian vessels, which would be able to provide training on the latest minesweeping techniques to naval reservists.
The two vessels had been constructed by Allied Shipbuilders Ltd. of Vancouver in 1973 and named
Joyce Tide and
Jean Tide - once acquired by the RCN, they were renamed HMCS
Anticosti (MSA-110), and HMCS
Moresby (MSA-112), respectively, after Canadian islands. The vessels sailed to Marystown, Newfoundland for conversion. In April 1990 they had their mechanical sweep gear and towed side-scan sonar fitted.
Anticosti and
Moresby were assigned to Maritime Forces Atlantic (MARLANT) as minesweeping training vessels in preparation for the future Maritime Coastal Defence Vessel Project (MCDV), which would become the
Kingston - class in the late 1990s. In March 1997,
Moresby transferred to CFB Esquimalt on the West Coast. Throughout the 1990s, the two vessels of the
Anticosti - class tested various technologies that would be used on the
Kingston - class vessels.
After the
Kingston - class MCDVs entered service, the
Anticosti - class was identified as surplus and both vessels were paid off in March of 2000. They were sold to commercial interests in January 2002.
