Gen. William Shelton, head of Air Force Space Command, has ordered an accident investigation board to determine why a Delta IV RL-10B-2 upper-stage engine failed to perform as expected during the Oct. 4 launch of a GPS IIF navigation satellite. Despite the anomaly, the Delta IV did deliver the GPS satellite “into its proper orbit,” states the command’s Oct. 11 release. However, “while the launch was ultimately successful, the time-honored rigor and earnest process of an AIB will serve us well as we attempt to determine the root cause of this anomaly,” said Shelton. He added, “In the end, our objective is continued safe and reliable launch for our nation.” The Air Force’s launch-manifest schedule is currently under review while the root cause is determined, states the release.
Lt. Gen. Dan Caine, nominee to be chairman of the Joint Chiefs of Staff, told the Senate Armed Services Committee that the Defense Department needs to upgrade its electronic warfare capability and its EW training ranges; just as his predecessor said at his own confirmation hearing.
