The Europeans are currently developing two sixth-generation fighters. One is the Tempest, being developed by the British, Japanese, and Italians, and the second is the Airbus Future Combat Air System (FCAS), being developed by the French, Germans, and Spanish. The Future Combat Air System is likely the one further behind on its development cycle. Airbus recently announced that it was partnering up with the startup company NeutralAgent to help develop the project.
