NEW YORK (CNNMoney) — Donald Trump wants to cancel government plans to build two new Air Force One jets.
The president-elect said in a tweet Tuesday that the new Boeing 747 jet that’s being built to carry “future presidents” already costs more than $4 billion, and that he wants to cancel the order.
Asked by reporters Tuesday morning about the tweet, he responded, “Well the plane is totally out of control. It’s going to be over $4 billion for [the] Air Force One program,” he said. “And I think it’s ridiculous. I think Boeing is doing a little bit of a number. We want Boeing to make a lot of money, but not that much money.”
Trump did not say why he believes the planes will cost “more than $4 billion.” Boeing says it currently has an Air Force Once contract worth $170 million.
A Boeing source familiar with the program told CNN that not even the company can estimate the cost of the program at this time since “the Pentagon has not even decided all the bells and whistles they want on the new Air Force One.”
Without knowing all the security features it is hard to give an estimated cost, the source added, and the Air Force isn’t even sure whether it wants two or three of the planes.
“We are not sure where he is getting that number from,” said the Boeing official.
In an official statement, Boeing that its current contract allows it “to help determine the capabilities of these complex military aircraft that serve the unique requirements of the President of the United States.”
So far the Air Force has budgeted $2.9 billion through 2021 for two new Air Force Ones, which will replace the aging pair of blue, white and polished aluminum 747-200Bs serving the President.
The new planes aren’t expected to be ready to fly until 2022. The Air Force has already spent about $93 million preparing to build the new jets, according to Defense Department budget documents. That $93 million is included in Boeing’s current contract. Manufacturing has yet to begin.
“We look forward to working with the U.S. Air Force on subsequent phases of the program allowing us to deliver the best planes for the President at the best value for the American taxpayer,” said Boeing’s statement.
The Air Force has yet to place a formal order for the new planes. It has chosen the latest version of Boeing’s jumbo jet, the 747-8, as the platform for the new Air Force One planes. Building the basic planes would take about two years. A team of engineers and aircraft machinists would then add state of the art communications, missile avoidance systems, inflight refueling, VIP interior and protections from the electromagnetic pulse of a nuclear blast. That takes years to do.
Boeing builds the 747 at its factories in Washington state, and it currently has a large back order for its commercial jets, especially the 787 Dreamliner. And airlines regularly cancel orders for planes, although it would be a loss of both prestige and revenue should the Air Force drop plans to build two new Air Force Ones.
The current planes have 4,000 square feet of interior floor space. The 747-8 can travel an additional 1,000 miles without refueling, fly faster with a heavier maximum takeoff weight and get better fuel economy than the 747-200 that’s used for the current Air Force Ones.
Boeing is the nation’s largest exporter. But it has recently been criticized by Trump for both its deal to sell commercial jets to Iran and its decision to open a factory in China to finish passenger cabins on planes purchased by Chinese airlines.
It did not immediately respond to a request for comment. Recently retired Boeing CEO Jim McNerney was named just last week to an all-star team of corporate executives who will advise Trump on jobs and the economy.
Shares of Boeing were slightly lower after Trump’s comment.
