Royal Canadian Naval Air Service

The Royal Canadian Naval Air Service (RCNAS) was established in 1918 during the First World War in response to the Royal Canadian Navy's recommendation that defensive air patrols be established off Canada's Atlantic coast to protect shipping from German U-boats. The United States supplied aircraft and personnel while Canada recruited and trained its own aircrew and support personnel who were intended to replace the Americans. RCNAS aircrew were trained in the United States and the United Kingdom.
