President Donald Trump said that the Qatar-gifted Boeing 747 will be taken out of service for about a month so it can be upgraded, but experts think it could take longer.

According to Reuters on Monday, the jet started carrying Trump on July 1, but its protection package drew attention after he changed planes mid-trip on July 8, flying an older Air Force One from Turkey to the United Kingdom as tensions with Iran climbed.

Douglas Birkey, executive director of the Mitchell Institute for Aerospace Studies, said the long-standing Air Force One fleet introduced in the 1990s includes advanced defensive gear such as anti-missile technology. But he believes the White House accepted less protection on the Qatar aircraft to get it operating faster. Birkey said any changes completed in roughly a month would probably center on non-kinetic options, including electronic jamming and infrared systems meant to disrupt heat-seeking missiles.

Mark Cancian, a senior adviser at the Center for Strategic and International Studies, agreed that the timeframe limits what can be accomplished. He said the work may amount to software changes or add-ons such as flares or chaff.

The news comes as Steve Parker, CEO of Boeing Defense, Space & Security, confirmed during an event in the U.K. that the company would be delivering two Air Force One aircraft in 2028, but warned that it could result in heightened costs for the company.

Meanwhile, Trump has faced sharp criticism from Democratic lawmakers over the $400 million Qatar-gifted Boeing 747, with Gov. Gavin Newsom (D-CA) earlier calling the aircraft the "Air Fraud One."
