Common Booster Core

The Common Booster Core (CBC) was an American rocket stage, which was used on the Delta IV rocket as part of a modular rocket system. Delta IV rockets flying in the Medium and Medium+ configurations each used a single Common Booster Core as their first stage, while the Heavy configuration used three; one as the first stage and two as boosters. The Common Booster Core was 40.8 metres (134 ft) long, had a diameter of 5.1 metres (17 ft) and was powered by a single RS-68 engine burning liquid hydrogen and liquid oxygen.
