Canada's military defense capabilities are at risk due to a predicted two-year delay of a new fleet of Earth-watching radar satellites, critics say. But the country's defense department maintains it has a backup plan.

The delayed Radarsat Constellation Mission (RCM) consists of three satellites meant to replace Radarsat-2, a five-year-old satellite that probes Canada's landmass, and that of other countries, with radar signals. Radarsat-2 is expected to last until 2015, and potentially longer.
