The most expensive aircraft ever, price tag USD 3.9 billion

Air Force One, the U.S. President’s plane is to be replaced with two new Boeing 747-800s by 2024.

Boeing got the contract for the two new Air Force One’s

After time consuming and extensive negotiations between the White House and Boeing Co. the deal is now on for Boeing, according to Bloomberg news.
The two Boeing 747-8s shall be delivered by December 2024. That would be the last year in office for President Trump if he wins a second term.

President Donald Trump shook up the U.S. defense industry via Twitter

Trump, known for his communication on Twitter, took the U.S. defense industry off guard when he put all large U.S. companies with governmental contracts on notice – but already on December 6. 2016, one month before he took office, he wrote on Twitter “Boeing is building a brand new 747 Air Force One for future presidents, but costs are out of control, more than USD 4 billion, cancel order”.
On the same day in an interview with CBS, Trump said the new Air Force One shall be painted in red, white and blue as the American flag, not in its traditional white, blue and light-blue color scheme.

Air Force One is a “Flying Fortress”

Much of the costs for the new airplanes come from pricy and complex modifications required to turn Boeing’s iconic hump-backed jets into the flying fortresses that ferry U.S. presidents around the world.
The Boeing 747-8s will be outfitted with dual auxiliary power units, rather than one electrical power system standard for commercial jets, along with a complex communication system, work and rest quarters for the first family, elevators to ease boarding, self-defense capabilities and other features.
The Boeing 747-8 is the only aircraft manufactured in the U.S., that when fully missionized meets the necessary critical important capabilities that the president needs, said the U.S. Air Force who oversees the project.
