Kingfisher is described as giving the destroyer a mine-detection capability. The operational objection is to sending a large, expensive combatant into a minefield to exploit that capability. Small mine-warfare craft, preferably uncrewed, are the alternative favoured in this comparison. The distinction is between possessing a sensor and accepting the risk of assigning the ship to a minehunting mission.
