The U.S. Air Force is anticipating a launch window for its sixth Boeing Wideband Global Satcom (WGS) spacecraft of 49 min. starting at 8:29 a.m. EDT Aug. 7.

The satellite, which will provide high-bandwidth data and voice communications for U.S. and Australian forces, will be lofted by a United Launch Alliance Delta IV with four solid-rocket motors and a 5-meter fairing, from Cape Canaveral.

Once launched, WGS-6 will be managed by Boeing at its El Segundo, Calif., control site along with WGS-5, which was launched in late May. WGS-6 is the final “Block 2” standard satellite, which includes a bypass to allow for quick transfer of video data collected by unmanned aircraft.

Boeing expects to hand off WGS-6 to the Air Force by the end of the year, after orbit raising and initial checkout.
