Lockheed CP-140 Aurora 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 Lockheed S-3 Viking. "Aurora" refers to the Roman goddess of dawn who flies across the sky each morning ahead of the sun. 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. The CP-140 Aurora is very
Aurora the same as that employed in plasma fusion laboratories throughout the world, and appears well able to account in principle for most – if not all – detailed properties of the electrons responsible for the brightest forms of auroras, above, below and within the acceleration region.
