The 11th Bombardment Group was activated on Hawaii on 1 February 1940 as a medium bomber group. In November 1940 it was redesignated as a heavy bombardment group, although it would not receive recognisably heavy bombers until the start of 1942. Those B-17s that arrived on Hawaii before the attack on Pearl Harbor went to the 5th Bombardment Group.
In the aftermath of the attack on Pearl Harbor the Hawaiian Air Force was reorganised as the Seventh Air Force. The 11th BG was only part of the Seventh from February-July 1942. During that time it carried out patrol and search missions off Hawaii, guarding against a repeat attack, gaining its B-17s during this period.
In July 1942 the group was transferred to the Thirteenth Air Force, moving to the New Hebrides. From there it took part in the campaign in the South Pacific. On 25 August, towards the end of the Battle of the Eastern Solomons, aircraft from the group sank the Japanese destroyer Muzuki. From November 1942 until March 1943 the group concentrated on targets in the Solomon Islands.
In March 1943 the group was transferred back to the Seventh Air Force and equipped with the B-24 Liberator. The Seventh Air Force was about to go onto the offensive as the Americans advanced across the central Pacific. Soon after joining the Seventh Air Force the group moved to Funafuti in the Ellice Islands, from where in June 1943 they made an unsuccessful attempt to attack the Japanese base on Tarawa. In November 1943 the 11th Bombardment Group resumed combat, taking part in the campaigns in the Gilbert, Marshall and Marianas Islands. This period began with a more productive return to Tarawa, where the group played a part in the pre-invasion bombardment of the island.
As the Americans advanced so did the 11th Bombardment Group. In October 1944 it moved to Guam, attacking targets in the Volcano and Bonin Islands. In July 1945 it moved again, this time to Okinawa, from where it attacked targets on the Japanese Home Islands.
