Common Core Booster

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.
