After the events of the September 11, 2001 attacks, Ellsworth deployed a number of B-1s in support of Operation Enduring Freedom. Aircraft from the 37th BS at Ellsworth AFB joined additional B-1s from the 34th BS at Mountain Home AFB and formed the 34th Expeditionary Bomb Squadron. This squadron, along with other elements from Ellsworth, deployed to Diego Garcia and joined the 28th Air Expeditionary Wing. Their combat mission effectiveness was greater than 95% and they flew 5% of the total strike aircraft missions. They dropped 39% of the total tonnage of bombs, which was more than any other platform. During their deployment the 28th EBS dropped 2,974 JDAMs, 1,471 Mk-82, 135 Mk-84, and 70 CBU-87 bombs. Currently, the 28th Bomb Wing and personnel from Ellsworth Air Force Base continue to be the lead wing for AEF 8, and Ellsworth personnel continue to prepare for ongoing deployments in support of operations around the globe.
