United Launch Alliance (ULA) is about to launch its mighty Delta IV Heavy rocket for the final time.
The mission will get underway from Space Launch Complex-37 at Cape Canaveral Space Force Station, Florida, on Thursday, March 28, with liftoff scheduled for 1:40 p.m.
For its 16th and final flight, ULA’s Delta IV Heavy rocket will launch the NROL-70 mission for the National Reconnaissance Office (NRO), deploying an intelligence satellite into a geostationary orbit.
ULA released a short video this week showing all of the various stages of the upcoming mission, from rocket engine ignition to the release of the satellite by the rocket’s final stage.

Thursday’s historic flight brings to a close six decades of service by the reliable family of rockets that Colorado-based ULA recently described as “the dependable Delta.”
The Delta IV Heavy, which first flew in 2004, has three boosters that make it bear some resemblance to SpaceX’s Falcon Heavy rocket, which flies using three Falcon 9 boosters.
ULA has been a joint venture between Boeing and Lockheed Martin since 2006. The company shuttered its Delta assembly line in Alabama in June 2023 after producing the 389th and final Delta rocket. The Delta IV Heavy and another ULA rocket — the Atlas V — are being replaced by ULA’s Vulcan Centaur rocket. The Vulcan took its maiden flight from the Kennedy Space Center in January.
