On 14 December 2006, with the launch of USA-193, was the first launch of the Delta II operated by United Launch Alliance. [15] The last GPS launch aboard a Delta II and the final launch from SLC-17A at Cape Canaveral occurred in 2009. The GRAIL Launch in 2011 marked the last Delta II Heavy launch and the last from Florida.
A Delta 2310 was the vehicle for the first three-satellite launch of NOAA-4, Intasat, and AMSAT-OSCAR 7 on 15 November 1974. [citation needed] Delta 2910 boosters were used to launch both Landsat 2 in 1975 and Landsat 3 in 1978. On 7 April 1978, a Delta 2914 launched "Yuri 1", the first Japanese BSE Broadcasting Satellite.

All launch vehicle propulsion systems employed to date have been chemical rockets falling into one of three main categories: Solid-propellant rockets or solid-fuel rockets have a motor that uses solid propellants , typically a mix of powdered fuel and oxidizer held together by a polymer binder and molded into the shape of a hollow cylinder.
Thor was a US space launch vehicle derived from the PGM-17 Thor intermediate-range ballistic missile. The Thor rocket was the first member of the Delta rocket family of space launch vehicles. The last launch of a direct derivative of the Thor missile occurred in 2018 as the first stage of the final Delta II.
In addition to its main engine, it includes two vernier engines to provide vehicle roll control during flight. [8] When used as the main booster propulsion system for the Delta II family of launch vehicles, has an operational duration of 265 seconds. The last RS-27A engine was used for the ICESat-2 launch on 15 September, 2018.
The Vulcan Centaur re-uses many technologies from ULA's Atlas V and Delta IV launch vehicles, [18] with an aim to achieve better performance and lower production costs. Also, unlike vertically integrated competitors like SpaceX and Blue Origin , ULA (itself a joint venture between Boeing and Lockheed Martin) relies heavily on subcontractors to ...
