The C-390 Millennium transits a runway before taking flight.
The C-390 was once Boeing's solution to the competing C-130 before it pulled out of the deal.
  • Boeing once wanted to buy a stake in Embraer's C-390 Millennium military aircraft.
  • The $4.2 billion joint venture aimed to boost Boeing's market reach and Embraer's resources.
  • The deal fell through in 2020 and left Boeing without a competitor to Lockheed's C-130 Hercules.

Boeing doesn't have an answer to US aerospace company Lockheed Martin's C-130 Hercules military plane — but it used to.
