WASHINGTON (Sputnik) — The launch of the US National Reconnaissance Office’s NROL-37 spy satellite mission has been postponed, United Launch Alliance (ULA) announced in a release on Friday.
"The Delta IV [heavy rocket] NROL-37 launch is delayed at the request of the customer," ULA stated. "The NROL-37 spacecraft and launch vehicle are secure on Space Launch Complex 37."
The ULA has originally scheduled the launch of the satellite from Cape Canaveral on the largest Delta IV rocket for June 4.
The ULA is a joint venture owned by Lockheed Martin and the Boeing Company. It brings together two of the launch industry’s most experienced and successful teams — Atlas and Delta — to provide reliable, cost-efficient space launch services for the US government.
