Area-B (AFC4) is located on a dry lake in the Railroad Valley region of Nevada and as you can tell by the codename it is meant as a supplement to Area-A which is located just a short 25nm to the south. This scenery area is very small and only serves as a weapons development and storage facility.  It has an ILS-equipped 10,000ft runway and hangars to accomodate most aircraft types, primarily cargo planes and bombers.
