Posted: Sun, Mar 17, 2019, 8:03 AM ET (1203 GMT)
Delta 4 launch of WGS-10 (ULA) A United Launch Alliance Delta 4 launched a military communications satellite Friday on the penultimate flight of the "single-stick" version of that rocket. The Delta 4 Medium-Plus (5,4) lifted off from Space Launch Complex 37 at Cape Canaveral, Florida, at 8:26 pm EDT (0026 GMT Saturday). The Wideband Global Satcom (WGS) 10 satellite separated from the upper stage in geostationary transfer orbit a little more than a half-hour later. WGS-10 will join a constellation of nine other satellite sin GEO providing military communications services. Only one more medium variant of the Delta 4 will launch, later this year, before that version is retired. The Delta 4 Heavy rocket, with its three first stage cores, will remain in operation for the foreseeable future.
