The Delta IV Heavy (Delta 9250H) is an expendable heavy-lift launch vehicle, the largest type of the Delta IV family. It is the world's second highest-capacity launch vehicle in operation, behind SpaceX's Falcon Heavy (with its core stage expended), and closely followed by CNSA's Long March 5. It is manufactured by United Launch Alliance and was first launched in 2004. The launch vehicle uses three RS-68 engines, one in the central core and one in each booster.
