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

The first flight of the Delta IV Heavy, featuring three Common
Booster Cores, was conducted on 21 December 2004. On this flight all three CBCs malfunctioned, cutting off prematurely due to cavitation in their oxidizer lines, and resulting in the rocket reaching a lower orbit than that which had been

The Delta IV made 45 flights; 29 in Medium and Medium+ configurations, and 16 in the Heavy configuration, resulting in a total of 77 Common
Booster Cores being launched. Delta IV retired on April 24 2024.
