# How much is the new Air Force One projected to cost?

President-Elect, Donald Trump recently tweeted that the cost of replacing Air Force One, the Presidents airliners would be 4 billion US dollars.

This figure is reported as accurate elsewhere.

Other news reports for listed a fraction of that as the current contract, 170 million dollars.

Will replacing Air Force One cost 4 billion US dollars?

• The \$170M contract is for designing, not building, the next Air Force One. The actual costs are forecasted to be about \$2.9 billion, although it's not uncommon for these to come in over budget. All this is explained by the articles you linked to - what's your question, exactly? – ff524 Dec 16 '16 at 1:31
• @ff524 The articles I've linked to say \$1.69B, \$2.9B & \$3B. No one has said as high as \$4B except Donny. My question is will it cost that much and how did he arrive at that number? – Coomie Dec 16 '16 at 1:56
• Is there a chance that different #s are due to in/excluding maintenance costs or other differences in accounting? There's a lot of ways to define what a project like that "costs" – user5341 Dec 16 '16 at 16:52
• @ff524 The \$170 M is just for requirements discovery and preliminary design work, not even close to all of the design work. – reirab Dec 17 '16 at 5:55

# Independent confirmation of cost from non-Trump source:

Your link in second paragraph has independent confirmation from NBC news (not exactly a hotbed of Trump support) twitter citing Air Force:

NBC Nightly News ✔ @NBCNightlyNews
US Air Force official: Price of new Air Force One project expected to be more than \$4B by time aircraft delivered - @ckubeNBC

# As to where the number comes from:

1. That link also shows the military form for "PE 0401319F: Presidential Aircraft Replacement (PAR)"

The total cost in the form (2015 through 2021) is 11.006+82.420+351.220+625.631+740.999+573.711+487.270 = \$2.9B

That number ONLY includes R&D ("3600: Research, Development, Test & Evaluation, Air Force / BA 5: System") and does NOT include procurement

2. Same Hannity article quotes procurement costs at ~1B, but the source is just a tweet from unknown guy.

However, this seems the right ballpark. A comment from @Mark states

Boeing's list price for the 747-800 is around \$400M for an unmodified airliner, and the Air Force is planning on buying two of them.

# If you take ~\$1B procurement at face value, that's where you arrive at \$2.9B+\$1B=\$3.9B, almost Trump's \$4B

• \$1 billion for procurement is reasonable. Boeing's list price for the 747-800 is around \$400M for an unmodified airliner, and the Air Force is planning on buying two of them. – Mark Dec 17 '16 at 0:38
• For what it's worth, Wikipedia suggests that the procurement unit cost for the current VC-25's was \$325 M and that was in the late 1980s. However, in a quick search, I didn't see a definitive source to back that up. – reirab Dec 17 '16 at 6:16
