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. 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. The seven module types available for embarkation include four route survey, two mechanical minesweeping and one bottom inspection modules.
