A Delta 4 Heavy lifted off early Thursday carrying a classified satellite. The rocket lifted off at 5:18 am EDT (0918 GMT) from Cape Canaveral Space Force Station in Florida after a one-day delay because of a ground system problem. The rocket is carrying a payload for the National Reconnaissance Office on a mission designated NROL-68. ULA and the Space Force declared the launch a success several hours later. One final Delta 4 Heavy launch is scheduled for next year.
