(Updated April 1- 10 a.m. EDT) - The launch of the Air Force's Wideband Global SATCOM-2 satellite aboard a United Launch Alliance Atlas V rocket is scheduled for April 3 with a launch window of 8:31-9:33 p.m. EDT. The Launch Readiness Review for the mission will be held later today and the Atlas V is scheduled to rollout to the pad at Space Launch Complex-41 at Cape Canaveral AFS, Fla., tomorrow at 9 a.m. EDT.This is third Atlas V launch for the Air Force following the STP-1 and WGS-1 launches in 2007. The WGS SV-2 mission marks the 15th Atlas V launch in program history and is the fifth overall launch for ULA in 2009. WGS SV-2 is the second installment of the Wideband Global SATCOM (WGS) system. WGS is an important element of a new high-capacity satellite communications system providing enhanced communications capabilities to our troops in the field for the next decade and beyond. The first spacecraft alone is providing more capacity than the entire Defense Satellite Communications System constellation currently on orbit. This equates to 10 times the capacity of DSCS. A third WGS satellite will launch on a Delta IV later this year.
