ISE Dorado Semi-Submersible
MCM and Survey Semi-Submersible
The growing threat from new-generation mines that are more difficult to detect has stirred interest for new minehunting systems that offer improved safety and efficiency. The ISE Dorado vehicle, acquired by the Canadian Department of National Defence, was developed to meet this need.
