Northrop Grumman launched three national security payloads for the National Reconnaissance Office (NRO) on the NROL-111 mission. The company used their solid propellant Minotaur I rocket to place the payloads into a low Earth orbit with a liftoff from Pad-0B at the Mid-Atlantic Regional Spaceport on Wallops Island, Virginia occurring on Tuesday, June 15 at 13:35 UTC (09:35 EDT).
Due to the classified nature of the launch, nothing is publicly known about the payloads. However, the mass must be less than 580 kg, which is the max payload capacity of the Minotaur I.
