These vessels were to be designed for crewing by a combined crew of approximately 37 Canadian Forces naval reservists and regular force members and were to have the capability to quickly change out "modularized mission packages" ranging from minesweeping to

Born from a need that dated back to the 1970s, the MCDV project was established to restore minesweeping capabilities to the
Canadian Navy along with providing at-sea training vessels for reservists. The decision to begin the program began in the 1987 National Defence White Paper under the concept of

SNC-Lavalin was instructed by the
Department of Public Works to use "CommercialâoffâtheâShelf equipment" which drove costs higher. One area of reported controversy was the decision by the government to only arm the ships with .50 calibre machine guns. Subsequent design modifications resulted in a

There were five main criteria for the design. The ships had to be built in Canada, they had to be inexpensive to build, they had to be operable by naval reservists, the design had to have role flexibility included, and they had to be inexpensive to operate. This was exemplified by the

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

Another area of controversy apparently resulted with the means by which the ships were to be ballasted in order to adjust the trim of the ships. The shipyard proposed to use
