Lockheed Martin’s F-35 Joint Strike Fighter is a super-expensive and technologically complex futuristic fighter. Magellan Aerospace, the Toronto based Lockheed-Martin supplier working on the plane, uses a fancy mechanical arm with a milling tool in their machine shop to make the tails for one variant of the Joint Strike Fighter. Maneuverability is key for milling tools, as they trim excess material away from parts, and need to do it with precision and from the closest angles. America’s next fighter is being built by Canada’s current generation of robots.

Here is the arm, demonstrated again:

No confirmation yet on whether it’s secretly full of writhing cats.
