When it was in service from 2004 to 2024, it was the largest type in the Delta IV family and was the world's second highest-capacity rocket in operation, behind SpaceX's Falcon Heavy rocket and closely followed by CNSA's Long March 5 rocket.[1][2] It was manufactured by United Launch Alliance and was first launched in December 2004 and was retired after its last flight on April 9, 2024.[3]
