Drawing of the Delta IV Heavy

Three Delta IV cores side by side, for several years the most powerful rocket in service. From 2004 to 2024 it launches heavy reconnaissance satellites, Orion's first test flight in 2014 and the Parker Solar Probe in 2018, each liftoff wrapped in a fireball of burning hydrogen.
