The Interdepartmental Maritime Integrated Command, Control and Communications (IMIC3) project includes participation from the Canadian Coast Guard and the Department of National Defence.
"We will deliver a robust national command and control network to both Coast Guard and naval units at sea as well as command centers ashore, that will considerably augment their operational capabilities," stated Paul Kahn, Thales' president and chief executive.
