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 Lockheed S-3 Viking. "Aurora" refers to the Roman goddess of dawn who flies across the sky each morning ahead of the sun.^[1] Aurora also refers to the Aurora Borealis, 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.
