The Delta IV Heavy rocket is scheduled for its final launch on March 29th from Cape Canaveral Space Force Station after 64 years of service.

The mission will carry a classified payload for the U.S. National Reconnaissance Office, marking the last mission of the Delta rocket family with 388 launches to date.

The Vulcan Centaur rocket is set to replace the Delta rockets, targeting 25-30 launches annually by 2025.

United Launch Alliance (ULA) will broadcast the historic final launch on their website.

The current weather forecast indicates a 30% chance of favorable conditions for the launch.
