Delta II was an expendable launch system, originally designed and built by McDonnell Douglas, and sometimes known as the Thorad Delta 1. Delta II was part of the Delta rocket family, derived directly from the Delta 3000, and entered service in 1989. There were two main variants, the Delta 6000 and Delta 7000, with the latter also having "Light ...

The Delta rocket family was a versatile range of American rocket-powered expendable launch systems that provided space launch capability in the United States from 1960 to 2024. Japan also launched license-built derivatives (N-I, N-II, and H-I) from 1975 to 1992. More than 300 Delta rockets were launched with a 95% success rate.
With the retirement of the Delta II launch system, the GPS IIR-1 mission stands as the only outright failure of a Delta II rocket. The only partial failure of a Delta II was the launch of Koreasat 1, where one of the solid rocket motors failed to separate; the satellite still reached its correct orbit by using onboard propellant, which left it ...
Delta II vehicles included the Delta 6000 and the two later Delta 7000 variants ("Light" and "Heavy"). The rocket flew its final mission ICESat-2 on 15 September 2018.

The launch was delayed several days due to high level winds and an issue with the rocket's propulsion system that was detected while the Delta 2 rocket was drained of fuel. 357 28 October 2011 09:48 Delta II 7920-10C VAFB SLC-2W: Suomi NPP / ELaNa III: 1,400 kg SSO: NASA / NOAA / DoD: Success [14]
The Delta second stage was derived from the Able second stage. Members of the Delta rocket family derived from the Thor-Delta continue to launch satellites and space probes. By 1969, the Thor core was being used regularly both in Delta vehicles and in the USAF Standard Space Launch Vehicle (SLV-2), with thrust augmentation and a variety of ...
