Ellsworth Rotates GSTF Airmen: 
The 28th Bomb Wing at Ellsworth AFB, S.D., has another 200-strong increment of airmen on its way to Andersen AFB, Guam, to replace the airmen deployed there since August as part of a Global Strike Task Force. The wing is leaving the six B-1Bs brought in by the first rotation, reports KUAM TV. Stateside bomber units have been deploying to Guam on four-month rotations to provide additional strike capability in the Pacific region.
The design of the launch facilities for the Air Force’s new Sentinel intercontinental ballistic missile are likely to undergo major revision, posing yet another challenge for the much-delayed and over-budget program to modernize the land-based component of America’s nuclear triad, officials said.
