Lockheed CP-140 Aurora

The Lockheed CP-140 Aurora is a maritime patrol aircraft operated by the Royal Canadian Air Force. The aircraft is based on the Lockheed P-3 Orion airframe, but mounts the electronics suite of the S-3 Viking. In Greek mythology, Aurora is the Greek goddess who restored Orion's eyesight, and also the Aurora Borealis are the "northern lights" that are prominent over northern Canada and the Arctic Ocean.

The CP-140A Arcturus was a related variant used primarily for pilot training and coastal surface patrol missions.
