The Air Force and United Launch Alliance (ULA) June 11 successfully launched the NROL-37 payload for the National Reconnaissance Office (NRO).

Liftoff took place at 1:51 p.m. EDT on a Delta IV Heavy at Cape Canaveral Air Force Station, Fla., according to a ULA statement. Launch was originally scheduled for June 9, but was delayed due to poor weather.

ULA’s next launch is the Atlas V Mobile User Objective System-5 (MUOS-5) mission for the Navy on June 24, also from Cape Canaveral. ULA is a joint venture of Lockheed Martin [LMT] and Boeing [BA].
