– CIMSEC – A key part of any modern navy is its rotary-wing component. The capabilities that helicopters bring to naval operations are essential in the context of modern warfare, and many large navies around the world boast impressive fleets of shipborne rotary-wing aircraft. Smaller navies, however, need to make due with much less, and there is perhaps no better example of a small navy employing its limited rotary-wing assets to the fullest extent as the Royal Canadian Navy (RCN).
