"Final Launch of Delta IV Heavy Rocket Scrubbed, Ending Era of Delta Rockets on Space Coast"
The final launch of United Launch Alliance's Delta IV Heavy rocket, scheduled for March 28, 2024, was scrubbed due to an issue with the gaseous nitrogen pipeline. The launch is now set for March 29, and it will be the 16th and final mission for the Delta IV Heavy, marking the end of the Delta rocket family's six-decade legacy. The upcoming launch will carry a classified payload for the U.S. National Reconnaissance Office, strengthening the agency's intelligence capabilities.
