The Common Core Booster (CCB) is an American rocket stage, which is used as the first stage of the Atlas V rocket as part of its modular design. It was also intended that two additional CCBs would be used as boosters on the Atlas V Heavy, however this configuration has not been developed. Use of a Common Core Booster as the first stage of the Japanese GX was also planned; however, this programme was cancelled in late 2009.
The Common Core Booster is 32.46 metres (106.5 ft) long, has a diameter of 3.81 metres (12.5 ft) and is powered by a single RD-180 engine burning RP-1 and liquid oxygen.[1]
Testing of the CCB and its RD-180 engines was conducted in the United States at the Marshall Space Flight Center, and in Khimki, Russia. The test programme concluded with the final engine test in December 2001.[2] The first launch of a Common Core Booster was the maiden flight of the Atlas V, which was launched from Space Launch Complex 41 at the Cape Canaveral Air Force Station on 21 August 2002.[3] As of January 2015, the Atlas V has made fifty-two flights, all of which have used a single Common Core Booster.[4]
