The majority of Intel's fabs are in the U.S., but they don't seem to be part of the DoD Trusted Foundry program. I'm not sure if there are barriers to them being certified, or if they just aren't interested.

The current list: http://www.dmea.osd.mil/otherdocs/AccreditedSuppliers.pdf

I believe that list is for fabs who can supply the DoD with custom/proprietary chips (i.e. with business models similar to TSMC or Samsung but for defense related products). Intel has not been in that line of business so there is no point in joining the program.

They did recently announce two fab customers, an FPGA manufacturer and then something else that is also low volume and obscure. So maybe the DoD can make it worth their while.

As of mid-2013 they had five fab customers [1]: Achronix, Tabula, Netronome, Microsemi, and Altera.

That one FPGA manufacturer, by the way, WAS started by people associated with the DOD intelligence apparatus. I can't remember the name of the company though, but they're making 22nm FPGAs on Intel's tri-gate process that they introduced with Haswell.

Intel generally does not fab other companies chip designs, with only a few exceptions.
