Why mine warfare needs a host ship rather than fleets of Magpies

Should the Royal Navy mass-produce Magpie-sized ships for mine sweeping?

A larger host ship deploying several smaller uncrewed mine-warfare craft is a more efficient force design.

Mass-producing Magpie-sized vessels as independent minesweepers would duplicate too many support functions. A larger ship can carry and launch smaller uncrewed systems tailored to detect, classify, and neutralize mines. The host supplies maintenance, command, communications, and human oversight that each small craft would otherwise need to duplicate. This model concentrates expensive support functions while distributing sensors and risk across multiple vehicles.
