What is this airport outside of Cairo, Egypt?
The two runways to the east form an existing air force base called Wadi Al Jandali AFB. The new western runway and terminal form a new civilian airport called Katameya/Al-Qatameya Airport. It is also known as Capital International Airport.

The airport is set to serve a new administrative capital that is yet to be completed.

Another new airport, Sphinx Airport, is west of Cairo. It is also adjacent to an existing AFB called Cairo West.


  Al-Qatameya will serve the new administrative capital project and the Cairo West airport will receive charter flights, along with Cairo International Airport to ease pressure.


They are not operational in the sense of scheduled air traffic. Google Earth shows what can only be the new Sphinx Airport (west of Cairo West AFB):
