The largest of the Delta 4 family, the Heavy version features three Common Booster Cores mounted together to form a triple-body rocket. This is the final flight of a Delta 4 rocket.

Not competitive with the Falcon Heavy. Musk is showing everyone, innovate or die.

Delta IV Heavy was always a cool rocket to watch. Destin had a video years back where Tory Bruno invited him to the pad and they climbed the mobile service tower for an up close look during the rollback.
 Delta IV Heavy Pad Tour, (with CEO Tory Bruno) - Smarter Every Day 199 This launch will also mothball launch complex 37. It was first built for Saturn I tests from 1964-1968  Then reactivated in the late 90's for the DeltaIV rockets.  |

Isn’t it the last because it uses the shuttle boosters and they have run out/past their life? I thought there was some rocket like that.

The Delta 4 uses RS-68A engines, one in each core. All American, but nothing re-usable so it has been priced out of the market by the Falcon Heavy. The Atlas 5 uses the Russian RD-180 which is no longer sold to the USA. There are still some here for launches if one wants to pay the price.

And there are enough Russian RD-180 engines left here to launch about 17 more ULA Atlas V missions over the next few years and they are already sold out for the Atlas V schedule then that rocket is done. |

"The LRR, led by ULA Launch Director Tom Heter III, took place in ULA's Delta Operations Center at the Cape and virtually via teleconferencing to assess the readiness of the rocket and mission assets, the status of pre-flight processing work and previewed the weather forecast that calls for a 30 percent chance of acceptable conditions due to a passing cold front and strong winds behind the passage." Mar 27 09:34 Update
That suggests that a launch delay may happen. |

Quote HistoryOriginally Posted By Pallas: Isn’t it the last because it uses the shuttle boosters and they have run out/past their life? I thought there was some rocket like that. NASA's SLS (Artemis) rocket uses reloaded Space Shuttle Solid Rocket Boosters (There are a few changes since Shuttle and one more booster segment per side vs original config.) and slightly modified Space Shuttle Main Engines (SSME) rocket engines (Rocketdyne RS-25 Rocket engines) (SLS uses 4 vs SS Orbiter use of 3/flight). SLS will be using up the current stock of previously flown booster segments and RS-25's, then they will have new design replacements. |
