A U.S. Navy F-5 Aggressor from VFC-13 based out of NAS Fallon sits on the tarmac at Stead Field, Nevada. Although the Northrup built F-5 does not serve as a front line fighter the aircraft was adopted for use as a opposing forces (OPFOR) role because of its small size and performance similar to the Soviet built Mig-21.
