MacDonald, Dettwiler and Associates Ltd. announced that it has signed a contract amendment for CAD 3 million with Canada's Department of National Defence to provide upgrades to the ground systems supporting the radar surveillance systems developed by MDA and used on Canada's fleet of CP-140 Aurora aircraft. The CP-140 Aurora fleet is Canada's Intelligence, Surveillance and Reconnaissance aircraft. The fleet is used by the Royal Canadian Air Force in activities such as domestic surveillance of Canada's maritime approaches, search and rescue missions, and maritime and overland operations.

MDA's radar surveillance system provides users with a high resolution imaging capability that can detect, locate, and classify land and marine-based objects, such as vehicles and ships.
