"The team is committed to getting the first one flying in 2028," said Allvin. 

"In the few short months since we made the announcement, they are already beginning to manufacture the first article," he continued, referring to the first test aircraft. "We're ready to go fast," he said. "We have to go fast." 

During a speech at this year's Air, Space & Cyber Conference, hosted by the Air & Space Forces Association in Maryland, Allvin announced that Boeing began work after being awarded a $20 billion contract in march. 

The new stealth fighter will replace the F-22 Raptor as the primary fighting aircraft in America's fleet. The program was briefly paused by the Biden administration, only to be revived under President Donald Trump - who announced the aircraft at a White House briefing, including its F-47 designation, a nod to the 47th president.

"Nothing in the world comes even close to it, and it'll be known as the F-47," said Trump.
