I think Lockheed Martin is bigger than Airbus. But note, that all the big aerospace companies are the products of mergers: Lockheed Martin is Lockheed + (Martin + Marietta ) Boeing is Boeing + Chance Vought + Sikorsky + Stearman + Pratt & Whitney + Vertol + Hughes + (McDonnell + Douglas) Airbus is Aérospatiale (Sud + Nord) + CASA + DASA (Daimler-Benz + Dornier + Messerschmitt-Bölkow-Blohm) + Matra The point being that these mergers require government approval, and in Airbus' case are mergers of nationalised companies. These companies only dominate because we let them.
