Report Suggests B-21 Bomber, Boeing 737, as New Air Force OneMore Back in December, Donald Trump caused a rucks when he tweeted that the costs for replacing Air Force One jets were "out of control." Now that Trump is in office, Defense Secretary James Mattis has ordered a full review of the $3.2 billion project to find ways to cut back costs.

According to popularmechanics, a new report from aerospace and defense analysts has gone so far as to suggest ditching the massive Boeing 747-8 as the airframe for Air Force One and instead modifying another aircraft for presidential use-perhaps Boeing's smaller 737, or even the B-21 stealth bomber still in development by Northrop Grumman.

Boeing is building a brand new 747 Air Force One for future presidents, but costs are out of control, more than $4 billion. Cancel order!

The biggest reason why they AF1 has always been a heavy jet is for the REDUNDANCY. From a Lockheed Constellation to a B707 to a B747.. hell, even going back to the Boeing 314, they have always relied on an aircraft with dual redundant engines. Even with ETOPS compliance and all the security requirements needed, a B737 loses that redundancy, let alone won't have the range to make it to most destinations they'd fly to] repots flightaware.

Is the president going to regularly fly in a blended wing body stealth bomber? Probably not. But whether the Commander in Chief will continue to fly in a Boeing 747 is anything but a certainty at this point.
