The president did not specify what the F-55 will be able to do, how much it might cost, or where it is in the procurement process.

The U.S. government, under President Donald Trump, is planning the development of a twin-engined warplane called the F-55 and an upgrade to the F-22 Raptor, dubbed the F-22 Super. Trump announced these new projects and other defense updates at a business meeting in Doha with leading aerospace executives.

The president has said that his administration is looking to develop a new fighter that will be a "substantial upgrade" from current models.
