The president-elect is not happy with his future airplane.

Donald Trump lashed out at airplane manufacturer Boeing for the exorbitantly high cost of the Air Force One plane currently being built.

“Boeing is building a brand new 747 Air Force One for future presidents, but costs are out of control, more than $4 billion. Cancel order!” Trump said Tuesday morning on Twitter.

Trump told reporters huddling at Trump Tower later in the morning that, “The plane is totally out of control. It’s going to be over $4 billion for Air Force One program 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.”

The Air Force ordered the two-plane set in 2015, when the price tag was estimated at $3.2 billion.

They’re not scheduled for delivery before 2023 — so Trump himself would only have use of the plane for the last two years his presidency should he be re-elected.

The new plane will reportedly be capable of midair refueling, be equipped to deal with the electromagnetic pulse of a nuclear explosion and be able defend against heat-seeking missiles.

Obama called Air Force One the perk he will miss most. “People sometimes ask me what the biggest perk of being president is,” he told a White House crowd in October 2015. “No. 1 is the plane.”

Trump, however, has been a critic of the current airplane being used to shuttle the president around.

“Air Force One is a very old Boeing 747. It sucks up a lot of gas. A lot of fuel. Boy, the fuel bill,” the then-presidential candidate said in July.

“A very old Air Force One, an old Boeing 747, with the old engines and, you know, spewing stuff,” Trump said last December.

Trump himself has a Boeing aircraft — a 757 — that was a frequent backdrop to his campaign rallies during the presidential election.

But the real-estate mogul did not buy the plane directly from Boeing. In 2010, he reportedly paid $100 million to purchase Trump Force One from Microsoft co-founder Pall Allen.

In the past, however, Trump has personally invested in Boeing. “.@Boeing stock went way down because of 787- so I just bought stock in @Boeing- great company!” he tweeted in January 2013.

A transition official said Tuesday that Trump sold his shares of the company in June.

If he canceled the Boeing contract, Trump would be following a precedent set by President Obama, who nixed a more than $13 billion contract with Lockheed Martin Corp. for a new fleet of presidential helicopters.

The Navy touted the move at the time as “allow[ing] the government to reduce program expenditures and take necessary steps to secure government property, preserve government equities and retain options for future decisions.”

Boeing did not immediately respond to a request for comment.
