Air Force One aircraft, there are two, are more than big airliners with a Federal paint job. It's a flying White House with a full (but classified so don't tell Hillary!) command and control center. Most here are old enough to recall that after 9/11, President Bush flew around in Air Force One for a few days until the extent of the attack was known. While his whereabouts were relatively unknown to the public (and our enemies) he was still in full control as Commander in Chief. This type of aircraft is not cheap. Hence why, as the linked article below details, the price tag on a pair of new Air Force One's is $4B.
The inaccuracies in Donald Trump’s Air Force One tweet
.....Congress obviously would have a say in the final price tag. The Boeing 757 jet used by the secretary of state was supposed to get long-range engines but at the last moment, they were killed by then-Sen. Ted Stevens (R-Alaska). This resulted in some cost savings — and also that the secretary of state would always have to refuel in Alaska on flights to and from Asia.
Boeing says it made no money making the last set of Air Force One jets and does not expect to make money on this order, as it is more a matter of prestige. Indeed, Boeing has already announced that it may soon end production of the 747 jet.
“Cancel the order!”
Nothing has been ordered yet. But the program could be eliminated. This may not be a problem for Trump, but certainly would affect his successors, especially if no order is placed before Boeing stops making 747s. The current aircraft were delivered in 1990, and as we noted, the life cycle is about 30 years. The Pentagon says the current fleet “faces capability gaps, rising maintenance costs, and parts obsolescence as it reaches the end of its planned 30-year life-cycle.”
Todd Harrison, a defense budget expert at the Center for Strategic and International Studies, said “the program is very new and hardly had a chance to get started yet.” So, in effect, there are no real cost overruns yet. He added that the estimated $4 billion cost is reasonable given the requirements of the project.
