Is it Jet A1 or JP-8?
If it's Jet A1, do they have a dedicated fleet of tankers for in-flight refueling or are the tankers able to seamlessly switch between JP-8 and Jet A1?

Re: VC-25A/B, E-4B - Type of Fuel
Probably JP-8, as that’s the US MIL standard, but fuels can be mixed. No dedicated tanker fleet in any case. Refueled, on the ground, in the ME for C-5s, burned whatever they gave us.

It’s actually Jet-A now. JP-8 cost slightly more per gallon, and the powers that be decided that $ wasn’t worth the benefits ~ 2016, so we’re all switched now.

After my time, jets will burn most anything combustive.

If I recall correctly JP-8 had negative health effects for folks that came in contact with it. None of my Fuels MX or POL friends had anything good to say about it.

Neat side-note-
if a NAVY bird gets anything but JP5 and goes to sea....
it gets treated 'differently' until all threat of the non standard fuel is gone.
My recollection is that it's about the flashpoint.

I'd believe it. Although on my jet between the JP-8, the skydrol, and the "potable" water kept in a tank that probably hasn't been cleaned since Reagan had naturally brown hair, the JP-8 was probably the least of their health concerns.

I knew that was a thing when the AF flew with JP-4, but do they do the same thing today when JP-8/Jet A is the tanking fuel? Definitely the flashpoint. JP-5>JP-4, although not nearly as safe as JP-7.

OT but out of curiosity, what did you fly?

JP-5 has a much higher flashpoint than JP-8 so its much safer for shipboard use.
