Delta 4 launch of WGS-7 (ULA) A Delta 4 rocket successfully launched the seventh in a series of military communications satellites on Thursday. The Delta 4 Medium-Plus (5,4) lifted off on schedule at 8:07 pm EDT Thursday (0007 GMT Friday) and placed the Wideband Global SATCOM (WGS) 7 satellite into a geostationary transfer orbit a little more than 40 minutes later. The Boeing-built WGS-7 satellite will provide military communications services at X- and Ka-band frequencies. The launch was postponed from Wednesday because of weather. The launch was also the first medium-class Delta 4 to use the upgraded RS-68A main engine in its first stage.
