Two dozen F-22 Raptors from the 3rd Wing and 477th Fighter Group lead a C-17 Globemaster III and an E-3 Sentry to conduct the largest-ever elephant walk at JB Elmendorf-Richardson, Alaska, during a Polar Force exercise. The 24 Raptors, which lined up loaded with external fuel tanks for extended range, represent about 13 percent of the F-22 inventory.
