Launch operator ULA launched a classified National Reconnaissance Office spy satellite on a Delta IV Heavy rocket on September 24th 2022 from Space Launch Complex-6 at Vandenberg Air Force Base, California USA.

The classified satellite NROL-91 is the Delta IV’s final mission from the West-Coast. The launch vehicle last flew in April 2021 when it orbited NROL-82.

About four minutes into flight, the outer boosters of the three-core Delta 4 Heavy separated. The second stage separated about two minutes later.

At the request of the NRO, ULA ended the webcast nearly seven minutes into the flight after the nose fairing was jettisoned.

NROL-91 was the 10th mission Delta IV Heavy launched for the NRO. The vehicle has flown 43 missions overall and 14 in the Heavy configuration.
