Taxpayers have not been told an exact figure, but official statements say the retrofit of the Qatar-gifted Boeing 747 did not exceed $400 million , while multiple independent reports and experts at the time warned the real cost could be ** closer to $900 million–$1 billion**.

What the plane is and why it’s called ā€œthe gift planeā€

The ā€œgift planeā€ is a Boeing 747‑8 that the Qatari royal family donated to the United States as an ā€œunconditional gift,ā€ valued at about $400 million. The U.S. government accepted it, and the Air Force was tasked with modifying it so it could serve as a temporary Air Force One until new Boeing-built presidential jets are ready.

Because the aircraft itself was a foreign gift, the jet’s purchase price was not paid by American taxpayers. The money taxpayers did pay was for:

  • Structural and systems modifications
  • Installation of secure communications and classified defense systems
  • Interior reconfiguration for presidential use
  • Testing, certification, and integration into the Air Force One fleet

All of that is what the question ā€œrefit the gift planeā€ refers to.

Official taxpayer cost ceiling: ā€œunder $400 millionā€

The Air Force’s public position to Congress has been that the retrofit cost has not exceeded $400 million. That is the only specific number the government has officially given.

In practical terms:

  • The Air Force has said the conversion will cost ā€œless than $400 millionā€.
  • In a June 2026 update, the Air Force reiterated that the retrofit ā€œhas not exceeded $400 millionā€.

So, if you’re asking what the government has officially admitted taxpayers paid , the answer is: up to $400 million , but not more than that (according to the Air Force).

Independent estimates: closer to $900 million–$1 billion

Multiple news outlets and experts, however, have suggested the true cost is likely much higher :

  • NBC News reported in May 2025 that experts told the conversion could cost around $1 billion.
  • Forbes cited reports suggesting renovation costs could be closer to $1 billion , not the sub-$400 million figure the Air Force had initially projected.
  • Some social media and forum discussions claim taxpayers paid about $900 million for the retrofit, though those are not official figures.

These estimates are based on:

  • The need to install classified communications and defense systems
  • Major structural changes to meet military and security standards
  • Lengthy engineering, testing, and certification work

The $1 billion figure has been repeated by:

  • Aviation specialists speaking to NBC News
  • Democratic lawmakers in hearings, who warned taxpayers could be forced to spend ā€œover a billion dollarsā€ to refit the aircraft

Why the exact number is unclear

The exact taxpayer cost is classified or at least not publicly detailed :

  • ABC News reported that the cost of retrofitting is classified , even though the donation itself was public.
  • The New York Times noted that the Air Force appears to have hidden or bundled the retrofit cost inside a larger, already over-budget program, making it hard to see the exact number.

So while the Air Force says under $400 million , independent analysts and media are warning the real cost could be roughly $900 million to $1 billion.

What this means for taxpayers

Putting it together:

  • Official ceiling : Air Force says taxpayers paid no more than $400 million.
  • Likely reality : Independent reports and experts suggest the cost is probably much higher, around $900 million–$1 billion.
  • Exact figure : Not publicly disclosed; the specific amount is treated as classified or not broken out in public budgets.

So the answer to ā€œHow much did it cost the taxpayers to refit the gift plane?ā€ is:

  • Officially : up to $400 million (Air Force estimate, not exceeded, according to the government)
  • Most likely in reality : around $900 million to $1 billion , based on independent reporting and expert analysis
