The next flight of United Launch Alliance’s triple-barrel Delta 4-Heavy rocket has been delayed from June to late August, military officials said Friday.

Launching the Wideband Global SATCOM 9 satellite purchased by allied nations in collaboration with the U.S. military’s worldwide communications network, a United Launch Alliance Delta 4 rocket thundered away from Cape Canaveral at 8:18 p.m. EDT (0018 GMT).
