National Guard KC-135 tanker units in six states recently swapped aircraft as part of a maintenance plan implemented by the Air Guard and Air Mobility Command, according to Air Guard officials. This initiative has two main goals: to arrange programmed depot maintenance schedules better so that one base isn’t short of airplanes for an extended period, and to prevent corrosion of the tankers by rotating them to other geographic regions, according to a Dec. 7 release from McGhee Tyson ANGB, Tenn., near Knoxville. Under the swap, the 134th Air Refueling Wing at McGhee Tyson and KC-135 units in Birmingham, Ala.; Phoenix, Ariz.; Topeka, Kan.; JB McGuire-Dix-Lakehurst, N.J.; and Milwaukee, Wisc., rotated one, and, in a few cases, two of their tankers to other units in this group. At the new home, maintainers repaint each KC-135’s nose art, localize its tail flash, and inspect it before it begins flying again, according to the release. (McGhee Tyson report by 2nd Lt.

Expanded production of the B-21 bomber can be accomplished at Northrop Grumman's existing Palmdale, Calif., facilities, the Air Force said. It also said test aircraft will be so simular to the production version that early examples could be used in combat if called for.
