On September 24, a United Launch Alliance Delta 4 Heavy rocket carried a classified satellite for the American National Reconnaissance Office into orbit.
The Vandenberg Space Force Base in Santa Barbara County, California, saw the launch of the NROL-91 spy satellite at 3:25 PM.
It marked the final Delta 4 launch from the west coast. More launches from Florida are planned before ULA switches to its newest Vulcan Centaur rockets to replace the Deltas.
In December 2004, the Delta IV Heavy configuration made its debut.This was the 387th Delta rocket flight since 1960 and the 95th and final launch from Vandenberg.
The National Reconnaissance Office is the federal organization in charge of designing, constructing, launching, and maintaining American spy satellites that deliver intelligence information to the Defense Department, the intelligence community, and policymakers.
