'Common Core Booster' (CCB) is the modular
liquid fuelled first stage of the
Atlas V expendable launch system. In most configurations a single CCB is used with strap-on
solid rocket boosters. For heavier loads three CCBs can be strapped together in the first stage. The Common Core Booster utilizes the Russian designed
RD-180 (rocket engine) burning
RP-1 fuel with
liquid oxygen producing a thrust of 4.15
MN
A similar design is used in the
Delta IV rocket. One or three liquid fuel modules can be used as the first stage. The Delta module is called the 'Common Booster Core' (CBC).
It uses the
Rocketdyne RS-68 engine and burns
liquid hydrogen with liquid oxygen producing a thrust of 2.9 MN.
