Delta 4 rocket on the pad for military satellite launch in December

The Delta 4 rocket that will launch the U.S. military’s highest capacity communications satellite ever built was rolled to the pad this week. The two-stage booster moved from the Horizontal Integration Facility to the Complex 37B pad and erected on the launch table to begin preparations for flight. Liftoff is scheduled on or about Dec. 7 during a window of 6:53 to 7:42 p.m. EST (2353-0042 GMT), a duration of 49 minutes. Over the next two months, using the classic launch pad design with a mobile service gantry, the rocket will undergo installation of four strap-on solid-fuel boosters, a rigorous checkout and testing campaign and mating of the satellite cargo.
