Gone is the trademark light blue hull that helped Air Force One blend into the sky.
The refurbished jet is painted in Trump's preferred colour scheme: a navy-blue belly with red and gold stripes.
It has the luxury features that the president believes a commander-in-chief's entourage should have - plush carpets, lie-flat seats, wood panelling and a presidential seal on the seat belts, according to reported tours of the plane.
Trump told reporters that he was proud of the luxurious plane.
"You can do two things: you can low-key it, or you can show it," he said on Wednesday.
The retrofitted Qatari jet is intended to serve as a "bridge" between the ageing Boeing jets that have served as Air Force One for the past 36 years and two new aircraft, which are years behind schedule and expected to be delivered in 2028 at the earliest.
Trump toured the new jet just weeks after returning to the White House in 2025 and directed that it be prepared for his use for the bulk of his remaining time in office.
The compressed timetable set by the president limited the modifications to the plane.
Images of the jet captured since its unveiling and analysed by the Associated Press show that it is not equipped with at least some of the same missile detection and countermeasure systems as the outgoing Cold War-era jets.
The Air Force has said it did little to change the cabin layout of the plane and that it spent less than $US400 million ($A580 million) on security upgrades.
Trump has said he plans to use the new plane when he travels to attend the NATO summit in Turkey on July 7-8.
The Air Force argued that the rapid conversion of the jet was done "without accepting any risk regarding security, safety, or secure communications",.
But it added that "several highly complex engineering modifications required for the final (Air Force One aircraft) were intentionally excluded from the Bridge aircraft".
The jet carried Trump to North Dakota to see the Theodore Roosevelt Presidential Library, its first official visitor before its opening on the nation's 250th anniversary.
The gift from the Middle Eastern power raised ethical concerns, but Trump saw the plane as a necessary replacement for the older planes that had previously ferried him as president.
"This is a gift from a country that has treated us very well," Trump said.
Trump has said in the past that the Qatar plane would end up in a presidential library.
