The F-18E-F is a Boeing operation, but Northrop Grumman makes the fuselage in El Segundo California. These are sent to St. Louis to be completed by Boeing.
Very cool operation, also saw the initial production parts of the F-35. Amazing stuff. Climate controlled tooling, parts and atmosphere to allow composits to mate perfectly later on in the assembly building in Palmdale.
They are tooling up to build the F-35 at 1 per day.
I was unaware that the F18-E/F was so different from the C/D. Bigger, composite instead of metal, more manueverable....etc.
