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 ...
Delta IV Medium+ (5,2), coded Delta 9250, was similar to the Medium+ (4,2), but had a 5-m–diameter DCSS and payload fairing for larger payloads. Because of the extra weight of the larger payload fairing and second stage, the Medium+ (5,2) could launch 5,072 kg to GTO.
Delta IV was a group of five expendable launch systems in the Delta rocket family introduced in the early 2000s. 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) product in 2006.
Falcon 9 Block 5, the most prolific active orbital launch system in the world.. This comparison of orbital launch systems lists the attributes of all current and future individual rocket configurations designed to reach orbit.
[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 ...
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 Delta IV and the lease on SLC-6 were turned over to United Launch Alliance (ULA) when ULA was formed as a joint venture of Boeing and Lockheed Martin Space in December 2006. On 20 January 2011, at 1:10 p.m. PST, USA-224 (NROL-49) was launched atop a Delta IV Heavy rocket.
The Common Booster Core (CBC) was an American rocket stage, which was used on the Delta IV rocket as part of a modular rocket system. Delta IV rockets flying in the Medium and Medium+ configurations each used a single Common Booster Core as their first stage, while the Heavy configuration used three; one as the first stage and two as boosters.
