(Portland, OR)  --  The Oregon Air National Guard has received the first of several new F-15EX Eagle fighter jets.  They're replacing the F-15C models that were built in the 1980s.  The new jets look similar, but have digital technology instead of analog technology which is in the older planes.  The Oregon Air National Guard flies out of the Portland Air Base near Portland International Airport.  The jets are used to keep the skies above the Pacific Northwest safe from threats.
