The Delta IV rocket, weighing 1.6 million pounds (725,748 kg) when fully fueled, consists of a triple-booster lower stage that produces 2 million pounds of thrust at launch, and a single-engine Firing up its three core boosters and RS-68A engines, the last 235-foot tall Delta IV Heavy rumbled into the record books Tuesday afternoon on a historic farewell flight from Cape Canaveral Space For additional thrust at liftoff, the Delta IV Medium+ used either two or four Northrop Grumman solid rocket motors (SRMs). The SRMs were strapped to the common booster core and jettisoned in-flight for maximum performance. Peak Vacuum Thrust: 280,000 lbf. Specific Impulse: 275.2 seconds. Length: 636 in. Delta IV was a group of five expendable launch systems in the Delta rocket family. It flew 45 missions from 2002 to 2024. It flew 45 missions from 2002 to 2024. Originally designed by Boeing 's Defense, Space and Security division for the Evolved Expendable Launch Vehicle (EELV) program, the Delta IV became a United Launch Alliance (ULA The Delta IV Heavy (Delta 9250H) was an expendable heavy-lift launch vehicle, the largest type of the Delta IV family. It was the world's third highest-capacity launch vehicle in operation at the time of its retirement in 2024, behind NASA's Space Launch System and SpaceX's Falcon Heavy and closely followed by CASC's Long March 5. It was manufactured by United Launch Alliance (ULA) and was The much-anticipated Delta IV Heavy rocket will potentially launch from Cape Canaveral − for the very last time − on Tuesday, April 9, with the launch at 12:53 p.m. EDT, pending range approval.
