Delta IV Heavy launching. The Delta IV Heavy (Delta 9250H) combines a 5 m (16 ft) diameter DCSS and payload fairing with two additional CBCs. These are strap-on boosters which are separated earlier in the flight than the center CBC. As of 2007, a longer 5 meter diameter composite fairing was standard on the Delta IV Heavy, [26] with an aluminum ...
The Delta IV Heavy (Delta 9250H) was an expendable heavy-lift launch vehicle, the largest type of the Delta IV family. It had the highest capacity of any operational launch vehicle in the world after the retirement of the Space Shuttle in 2011 until the Falcon Heavy debuted in 2018, and it was the world's third highest-capacity launch vehicle in operation at the time of its retirement in 2024.
The launch was conducted by ULA and was the first flight of a Delta IV Heavy from Vandenberg. [35] On 24 September 2022, ULA launched the last Delta IV Heavy from the pad, concluding their use of SLC-6. [36] Vulcan Centaur, Delta IV Heavy's successor, will launch from SLC-3E at Vandenberg, currently used by Atlas V. [37]
[5] [6] The RS-68 was certified in December 2001 for use on Delta IV rockets. [7] An RS-68 was part of each Delta IV Common Booster Core. The largest of the launch vehicles, the Delta IV Heavy, used three CBCs mounted together. [8] The engine produced 758,000 pounds-force (3,370 kN) in a vacuum and 663,000 pounds-force (2,950 kN) at sea level ...
A heavy-lift launch vehicle (HLV) is an orbital launch vehicle capable of lifting payloads between 20,000 to 50,000 kg (44,000 to 110,000 lb) (by NASA classification) or between 20,000 to 100,000 kilograms (44,000 to 220,000 lb) (by Russian classification) [1] into low Earth orbit (LEO). [2]
The Delta IV Heavy rocket has three Delta IV core stages together. According to the ULA website, each rocket engine produces up to 702,000 pounds of thrust. With this performance, one can see why ...
Delta IV Medium was retired in August 2019 and Delta IV Heavy retired in April 2024. After a two-year solicitation and competition process in 2018–2020, in August 2020 the USSF selected SpaceX (F9 and FH) and ULA's yet-to-be-certified Vulcan Centaur to supply US military launch requirements in 2022–2027.
