ABC News reported that Trump will use the plane as a new version of Air Force One until shortly before he leaves office in January 2029, when ownership will be transferred to the foundation overseeing his yet-to-be-built presidential library.
The gift is expected to be announced when Trump visits Qatar as part of a trip that also includes stops in Saudi Arabia and the United Arab Emirates, the first extended foreign travel of his second term.
Administration officials, anticipating questions about the president accepting such a large gift from a foreign government, have prepared an analysis arguing that doing so would be legal, according to ABC.
The Constitution's Emoluments Clause, Article I, Section 9, Clause 8, bars anyone holding government office from accepting any present, emolument, office or title from any "king, prince, or foreign state," without congressional consent.
Trump intends to convert the Qatari aircraft into a plane he can fly on as president, with the Air Force planning to add secure communications and other classified elements to it.
But it will still have more limited capabilities than the existing planes that were built to serve as Air Force One, as well as two other aircraft currently under construction, according to a former US official.
The existing planes used as Air Force One are heavily modified with survivability capabilities for the president for a range of contingencies, including radiation shielding and anti-missile technology.
They also include a variety of communications systems to allow the president to remain in contact with the military and issue orders from anywhere in the world.
The official told Associated Press that it would be possible to quickly add some countermeasures and communications systems to the Qatari plane, but that it would be less capable than the existing Air Force One aircraft or long-delayed replacements.
Neither the Qatari plane nor the upcoming VC-25B aircraft will have the air-to-air refuelling capabilities of the current VC-25A aircraft, which is the one the president currently flies on, the official said.
Air Force One is a modified Boeing 747.
Two exist, and the president flies on both, which are more than 30 years old.
Boeing has the contract to produce updated versions, but delivery has been delayed while the company has lost billions of dollars on the project.
Delivery has been pushed to some time in 2027 for the first plane and in 2028 — Trump's final full year in office — for the second.
ABC said the new plane is similar to a 13-year-old Boeing aircraft Trump toured in February, while it was parked at Palm Beach International Airport and he was spending the weekend at his Mar-a-Lago club.
Trump's family business, the Trump Organisation, which is now largely run by his sons, Donald Trump Jr and Eric Trump, has vast and growing interests in the Middle East.
That includes a new deal to build a luxury golf resort in Qatar, partnering with Qatari Diar, a real estate company backed by that country's sovereign wealth fund.
Administration officials have brushed off concerns about the president's policy interests blurring with the family's business profits.
They note that Trump's assets are in a trust managed by his children and that a voluntary ethics agreement released by the Trump Organisation in January bars the company from striking deals directly with foreign governments.
But that same agreement allows deals with private companies abroad.
That is a departure from Trump's first term, when the organisation released an ethics pact prohibiting both foreign government and foreign company deals.
White House press secretary Karoline Leavitt, when asked Friday if the president during his upcoming trip, might meet with people tied to his family's business, said it was "ridiculous" to suggest Trump "is doing anything for his own benefit".
