How much did it cost the taxpayers to refit the gift plane?

July 2, 2026

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 “the gift plane”

The “gift plane” is a Boeing 747‑8 that the Qatari royal family donated to the United States as an “unconditional gift,” 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 “refit the gift plane” refers to.

Official taxpayer cost ceiling: “under $400 million”

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 “less than $400 million”.

In a June 2026 update, the Air Force reiterated that the retrofit “has not exceeded $400 million”.

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 “over a billion dollars” 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 “How much did it cost the taxpayers to refit the gift plane?” 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
